Cut Costs, Cut Emissions

That was the result for Mississippi-based Blessey Marine when they used AXI Internation’s fuel conditioning systems

Blessey operates 80 tank barges and 40 tow boats, ranging from 700hp to 3,200hp, and port engineer Mark Dufriend turned to AXI after having major problems with on of his barges.

"I was changing fuel filters every 17 hours and was ready to send the barge to the shipyard and have the fuel tanks pumped out and cleaned," he said.

He first tried treating the fuel with AXI’s AFC-705 fuel catalyst ... which solved the problem. After several months and 200 hours without a fuel filter change, Mark estimates that the savings on tank cleaning alone exceeded US$5,000 -- and he now treats fuel tanks on all Blessey’s boats and barges.

Based on the success of the fuel catalyst, Mark went on to install the firm’s LG-X 3000 fuel conditioners on 95ft workboat Dreamer Klaiber, fitted with 3,200hp Cummins KAT50-M2 engines.

Dreamer Klaiber Workboat

"Before installing the fuel conditioners on the main engines and generators, the fuel filters needed replacement at every oil change," Mark continued. "Afterwards, the captain finally replaced the fuel filters at the third oil change -- he just felt guilty, the filters really didn't need changing!"

That convinced Mark to institute a total fuel systems management program that will see LG-X series conditioners installed on all Blessey’s boats and barges.

"Our technology is about optimizing the fuel quality to perform better," AXI’s Bill O’Connell told DPC. The firm also worked with dredging contractors Manson Construction to help cure their fuel and emission problems and, Bill continued: "Our systems aid filtration, but that same benefit results in better fuel combustion -- Manson saw less particulate emissions as well as better fuel consumption."

Excerpt from the November, 2004 issue of Dredging and Port Construction magazine article entitled A Breath Of Fresh Air?

The AXI Fuel Catalyst (AFC) line of fuel additives are High Performance, Full Spectrum Additives in a Concentrate that removes and prevents carbon-based deposits in the combustion chamber, eliminates microbial contamination, clogged filters and the build up of sludge in fuel storage and delivery systems. These industrial quality additives incorporate fuel stabilizers and intense cleaning agents that prevent sludge build-up in tanks, improves combustion, reduces harmful emissions, and eliminate the need for expensive and toxic biocides. The AFC family of additives are formulated for use in diesel, gasoline, bio-fuels, kerosene and HFO (also known as heavy fuel oil or residential fuel oil).

AXI Fuel Catalyst is not like other additives readily available at truck stops, auto and truck parts retailers, marine supply stores, or sold by numerous on-line suppliers.

AFC is formulated and blended for the focused dual-purpose of: First - working hand-in-hand with AXI Fuel Conditioning and Tank Cleaning Systems, either the Mobile Systems or the Automated Systems, cleaning fuel tanks in preparation for periodic circulation and treatment of the fuel; and Second - as a continuing part of a Fuel Management Plan to maintain the cleanliness of storage tanks and fuel systems and assuring that your fuel maintains Optimal Fuel Quality, that we define as

, for as long as you depend on the fuel to efficiently operate your equipment.

The AXI Fuel Catalyst Family of Products

The AXI Fuel Catalyst Family of Products consist of three products that address three very specific uses.

AFC-710 Diesel Fuel Catalyst -- The AFC-710 Diesel Fuel Catalyst is available in both a liquid and a powder form, providing great flexibility in how you treat your diesel fuel, and is Tier 4 Compliant. AFC-710 has a chemical affinity to the hydrocarbons in your diesel fuel, helping your engine tap into your fuel’s full potential by burning it more completely. While it is doing so, it’s also cleaning your fuel system, from the fuel tank to your injectors, to your combustion chamber, and through to your exhaust. You can expect AXI’s Fuel Catalysts to improve your fuel economy, increase your horsepower, add engine lubricity, and extend DEF and UREA lifespan, especially if you have not regularly used a fuel additive in the past. AXI’s AFC-710 Fuel Catalyst meets EPA standards and will work with other additives – but you won’t likely need them anymore.

AFC-805 Diesel Fuel Catalyst - Cold Weather

AFC-805 Catalyst &

Cold Weather Use

Click on Graphic

AFC-805 Anti-Gelling Broad Spectrum Fuel Additive -- AFC-805 is a unique and powerful fuel additive specifically formulated as part of a preventative fuel maintenance program, and is ideal for use in bulk storage fuel tanks in cold weather environments. AFC-805 effectively decontaminates and cleans an engine’s entire fuel and injection system. It continues to work in storage tanks cleaning and stabilizing fuel for up to 12 months with a single dose. AFC-805 is ideally used for cold weather applications where there is long term fuel storage, such as bulk fuel farms, winterized recreational and work boats, and smaller engines.

How the AXI Fuel Catalyst Products are Different

The formulation of AFC-705 Diesel Fuel Catalyst includes surfactant and dispersant components that break down and dissolve sludge and organic debris. Prior to adding AFC-705 to your tank as part of a fuel conditioning and tank cleaning undertaking, it is recommended that a circulation system or other means be used to remove free water from the tank bottom for proper disposal. However, it is difficult to be assured that all water is removed during this initial phase of the tank cleaning process regardless of the means used. The surfactant that is a component in the AFC-705 will emulsify this residual water that remains in the tank bottom after an active water removal process up into the fuel for removal in the subsequent circulation process with the use of water block coalescing filters, returning the fuel to a "clear and bright" state from the cloudy, foggy looking fuel that has water mixed with the fuel (for more information on the circulation process, see the "Cleaning a Fuel Tank" Guide. However, the surfactant components of the formulation are not in compliance with the requirements of Tier 4 additives.

AFC-805 enhances the breakdown and removal of sludge, slime, and bio-fouling from tank walls and baffles in fuel tanks, and has components that make it ideal for use in bulk storage fuel tanks in cold weather environments. AFC-805 is likewise not compliant with Tier 4.

The formulation of AFC-710 is a unique and powerful Tier 4 compliant broad-spectrum additive concentrate that, in combination with good housekeeping, will stabilize your fuel, prevent sludge build-up, and eliminate the need for expensive and toxic biocides. It includes in its formulation combustion catalysts, dispersants, corrosion inhibitors and lubricity enhancers.

All AFC Catalyst additives will accelerate the tank cleaning and fuel conditioning process when used with an AXI Mobile or Automated Fuel Conditioning and Tank Cleaning System. It will effectively decontaminate and clean the entire fuel and injection system and continues to work in storage tanks cleaning and stabilizing fuel for six months or longer.

AFC Benefits Explained

The benefits of using AXI Fuel Catalyst are derived from its unique formulation of dispersants, surfactants, combustion enhancers and deposit surface modifiers, targeting problems of contaminated fuel systems in storage tanks and deposits in engines, turbines and burners.

  • Remove Engine Deposits -- AFC combustion catalyst removes deposits by interacting with the surface of the deposit, lowering the energy of activation of its chemical bonds. This allows the release of carbon in the form of C02 at the lower temperatures.

  • Prevent Deposit Formation -- The AFC catalytic components inhibit the agglomeration process from forming heavy deposits. The agglomeration process is stopped at the primary and secondary particle formation phase, which results in smaller, lighter particles.

  • Reduce Fuel Consumption -- Deposits in the combustion chamber absorb and protect the fuel from complete combustion. AFC catalyzes the combustion process. It destroys and removes deposits, which leads to the more efficient conversion of the fuel to C02. The surfactant component in AFC reduces the fuel droplet size, which enhances the combustion process, burning a higher percentage of the fuel before the exhaust valve opens. AFC treated fuel immediately reduces fuel consumption by 5 to 10% in comparison to fuel used in high mileage engines that have not been treated with combustion chamber cleaners or additives with similar components.

  • Reduce Emissions. -- As deposits are removed, the emissions of CO, NOx, SOx, HC and particulates are drastically reduced.

  • Reduce Carbon Content of Ash. -- The catalyst interferes with the agglomeration of combustion by-products by enhancing C02 production. With less carbon available to end up in the ash complex, the amounts of ash or soot will be significantly reduced.

  • Cooler Exhaust, Lower NOx. -- Fuel has a limited amount of energy that becomes available during combustion through the production of C02. The catalytic components in AFC enhance the combustion process. When more of the fuels’ energy is released during the combustion phase, less energy will be available to be released during the exhaust phase. The difference in energy release correlates to a temperature difference. Higher energy release in the combustion chamber means lower energy release during the exhaust phase, which results in cooler exhaust, lowering the production of NOx.

  • Extend lube-oil life. -- AFC treated fuel produces smaller and less abrasive particles, which in connection with the removal of deposits, result in cleaner, longer lasting lubrication oil, and leads to reduced engine wear, less maintenance and down time, lowering operating cost.

  • Extend Equipment life. -- Engine life can be more than doubled as the result of complete deposit removal, cleaner oil and reduced friction. Injectors, valves, rings and other associated parts show little sign of wear, even after extended use.

  • Enhance Fuel Lubricity -- With the AFC’s Lubricity Enhancers, engine components that depend on the lubricity of diesel fuel during operations will last longer.

  • Inhibiting Corrosion -- With the AFC Corrosion Inhibitor, injectors and other components in the fuel system will last longer and maintain optimal performance.

Use of AXI Fuel Catalyst in the Tank Cleaning Process

One gallon of AFC-705 or AFC-710 cleans a full 5,000-gallon fuel tank for a regular preventative maintenance treatment. If you are treating a tank that is more than five years old for the first time, or you are treating a tank that you know is contaminated, it is recommended that you use a double dose, using one gallon of fuel to 2,500-gallons (see other treatment ratios below). This full spectrum additive package cleans the entire diesel fuel system, restores diesel fuel quality and provides Optimal Diesel Fuel Quality for engines and storage tanks, improving fuel economy, reducing emissions and lowering operating cost, maintenance and down time.

It is generally agreed that most engine failures originate in the fuel tank. Frequent fuel filter changes, fuel dialysis and tank cleaning are generally viewed as good house keeping, and have become accepted as standard periodic maintenance.

The normal aging process of the fuel is often accelerated by microbial contamination, chemical incompatibility and condensation of water in the system. Oxidation, polymerization and stratification will lead to darkening of the fuel, the build up of tank sludge, filter plugging, corrosion, and fuel breakdown. We will see a slimy, jelly like layer develop in the water-fuel interface, while a bio-film is growing on the bottom, walls and baffles of service and storage tanks, inside fuel lines and delivery systems.

The process of fuel breakdown is most severe in the bottom of our tanks. Every time we fill our tanks, we mix and contaminate the fresh fuel with our residual fuel, and add new oxygen, which accelerates the problem. Because we primarily use the higher and therefore dryer layers of the diesel fuel, it is easy to overlook the symptoms of this continuous process of fuel breakdown.

Suddenly we get a wake up call, and experience some or all of these symptoms:

  • Clogged filters

  • Fouled and Corroded Injectors

  • Smoking Engines

  • Loss of Power and RPMs

  • Fuel Pump Problems

  • COMPLETE ENGINE FAILURE

All of this can be prevented by simply monitoring fuel quality, and using the available AXI technology.

The surfactants and dispersants in AXI Fuel Catalyst completely break down and dissolve the tank sludge and bio-film. It eliminates clogged filter elements and recovers the BTU value that would otherwise be lost.

Traditionally tank cleaning meant filtering the fuel in the tank, or removing the fuel for filtration, or complete fuel disposal often in conjunction with opening the tank and physically removing tank sludge and bio-film. All these techniques are time consuming, costly and only partially effective, in particular when we realize that filtration will only remove the suspended debris and has no effect on the bio-film growing on tank walls, bottom and baffles, or on the process of fuel break down. At best we can expect only temporary relief at an extremely high price.

We recommend the use of AXI Fuel Catalyst to completely decontaminate and clean the entire fuel system, with the simultaneous installation of an In-line AXI Fuel Conditioner to insure continuous Optimal Fuel Quality, enhanced combustion, and reduced emissions.

The Loss of the Natural Microbial & Fungal Biocide with the Mandate for Ultra Low Sulfur Fuel (ULSF)

When the EPA mandated the switch to 15 ppm of sulfur content in diesel fuel in 2007, introducing the era of Ultra Low Sulfur Diesel (ULSD), the agency allowed for a phase-in period, but by 2015, all diesel fuel both on-road and off sold in the U.S. had transitioned to ULSD. This sulfur removal has caused a major problem with microbial growth in diesel tanks, both storage tanks and operating equipment tanks, because the natural biocide provided by the sulfur in the fuel has been substantially eliminated.

Sulfur acts as a natural biocide that had helped prevent microbial growth in diesel fuel tanks. This microbial growth is not algae, although many people think it is. The slimy debris that clogs fuel filters and is visible floating around in fuel is actually a bio-mass that is a byproduct of the reproduction of the microbes that utilize the water in the tank bottom as a habitat, feeding off the additives in the diesel fuel at the fuel-water interface in the tank bottom. Removing the sulfur made the fuel much less resistant to fuel microbes, including fungus, mold, and bacteria.

Microbes, mold and bacteria may be introduced into a fuel tank with a fuel fill-up, but it is more common for this contamination to come in through the air vent. As fuel is used, it is replaced with air drawn into the tank through a vent, and this air contains moisture and the microbes and fungi that develops into a real problem. Storage tanks, especially above ground tanks, "breath" as the tank warms during the day and the heated fuel expands, pushing air out of the tank, and then contracts as the fuel cools at night, drawing moisture and contaminants in through the vent.

Desiccant Fuel Tank Breathers

It may take up to nine months for the microbial growth to develop before the fuel starts showing the symptoms of microbial growth. Clogged and slimy filters, dark hazy fuel, floating debris in the tank, sludge build-up, loss of power and RPM, excessive exhaust smoke, corroded, pitted fuel injectors and a foul odor emitting from the fuel tank. Any of these symptoms indicate a serious fuel problem.

Preventing this situation is critical. The use of an air vent that prevents the drawing in of moisture and microbes in through the vent is an absolute must. Desiccant Fuel Tank Breathers contain material that absorbs moisture as the air is drawn into the tank, and filters dust, pollen and other organic components, as well as dirt, grit, and other particulates that carry the micro-organisms, bacterial growth, fungal growth, enzyme activity, yeast, mold, and pollen into your fuel tank. Stopping this flow should be the first step to stopping the problem.

The most critical steps you can take in controlling microbial growth is in robbing the microbes of their habitat. Checking for water on a regular basis (every 30 to 60 days) using Kolor Kut Water Finding Paste and removing any water that is detected will reduce the likelihood of an infestation in your tank, but will not absolutely prevent it as even residual water left behind when a tank bottom is pumped to remove water can harbor an infestation.

Water Eliminator

Using a device known as a Water Eliminator, available for smaller tanks in a 12" size and a 31" version for use in storage tanks, crystals in the Water Eliminator absorbs the water but will not absorb diesel fuel. The water in the bottom of the tank will be held in the device and not spread over the bottom of the tank. At periodic inspections at fuel fills, when the device has absorbed its full capacity of water remove it and replace with another for ongoing protection.

Periodic treatment of fuel with AFC dissolves the bio-mass, and periodic circulation of the fuel is necessary to assure the tanks are clean, free of water, and any microbes left behind is not reproducing. The AXI In-line Fuel Conditioner sees to that.

Biocides are Not the Answer, They Are Part of the Problem

Unfortunately, by the time you realize you have a problem, the effectiveness of biocides are limited. If a heavy bio-film has accumulated on the inside surface of the tank or other fuel system components, the biocide may not be able to penetrate this film to reach the organisms living deep within the film. You may see short term relief, but the problem quickly returns as the remaining organisms further reproduce.

Frequently, the application of a biocide aggravates the situation and converts what bio-film that is treated into solids, creating a real fuel filter nightmare. The introduction of a biocide into a fuel tank results in the organic materials turning into a grit that settles to the tank bottom. Then, each time you re-fuel, these materials are stirred up and find their way into your fuel line. As a further complication in the use of biocides, the removal of water from a tank bottom that was treated with biocides must be disposed of appropriately because biocides are toxic.

As Diesel Fuel Ages, Heavy End Asphaltenes Rob Engine Performance

As diesel fuel ages and it is exposed to air, water, and other factors, its heavy-end asphaltene content will become unstable and start to drop out of suspension in the fuel. When old fuel appears dark or even black, this is caused by the agglomeration of the asphaltene component. As these solids grow in size, they drop to the tank bottom and add to the sludge and debris. They clog your fuel filters and the filters turn black. If you have ever looked inside a fuel tank, and the tank bottom appears to be painted with roofing tar, this is what the accumulation of the asphaltene debris looks like. The AFC will, over a period of time with regular use, clean this accumulation in your tank, and with ongoing circulation through the AXI In-line Fuel Conditioner, either mounted on your fuel line or, with periodic treatments utilizing a Mobile or Automated Fuel Conditioning and Tank Cleaning Systems, will go back into solution, allowing the fuel to regain its "clear and bright" appearance. This returning dark fuel to bright fuel is where the term "Fuel Polishing" originated.

The Shelf Life of Diesel Fuel is Getting Shorter

According to Caterpillar, ULSD has a shelf life, even when all basic fuel storage maintenance practices are followed by the distributor, of one year beginning when the diesel fuel leaves the producer, and six months for bio-diesel and blended bio-diesel. At temperatures above 86 deg. F (30 deg. C), diesel and bio-diesel fuel storage life is cut in half.

However, Cat contends that diesel fuels can deteriorate rapidly when fuel is "stressed". The high pressure (in excess of 30,000 psi) and high temperatures (fuel is used as a coolant for high-pressure fuel injection systems) that the fuel endures as it is repeatedly recirculated back to the fuel tank is responsible for much of fuel degradation. Gums and resins that occur in diesel fuel under these stressful conditions are the result of dissolved oxidation products in the fuel that do not evaporate easily and do not burn cleanly. Excessive gum in the fuel will coat the inside of fuel lines, pumps and injectors and interferes with the close tolerances of the moving parts of fuel systems (Caterpillar’s publication SEBU6251-17 "Cat Commercial Diesel Engine Fluids Recommendations", Page 45).

Lubricity Enhancer & Corrosion Inhibitor Needed in ULSF

In today’s low sulfur fuel, many of the fuel components that contribute to the lubricating properties of the fuel have been removed. The components used to formulate the lubricity enhancers in AXI Fuel Catalyst work to offset the lower lubricating properties in two different ways, and over two different temperature ranges.

  • The first component works by coating the surfaces with a protective lubricating film. This film also acts as a corrosion inhibitor, which keeps the parts clean and free of pits. The film works best at lower temperature up to about 300 deg. C , and is constantly being replenished as it is broken down by friction and heat.

  • The second component breaks down large abrasive particles into smaller smoother particles. This component works at temperatures higher than 200 deg C, and continues to work in conjunction with the combustion catalysts once it enters the combustion chamber.

The two components together address corrosion, lubrication and friction problems over the entire engine operating temperature range, and inhibit the formation of acids. AFC lubricity enhancers will not change the fuel specifications in any way. The sulfur content, BTU value and other specifications will remain unchanged.

The principle benefit of AFC lubricity enhancers is the extended life of engine parts that rely on the fuel for lubrication. Keeping these parts operating normally solves many of the problems related to switching from a regular to a low sulfur diesel fuel. A small increase in available power will be noticeable due to lower friction.

Engine parts will be more resistant to acid corrosion and will show less wear due to carbon grit. As a result, engine lubricating oil will stay cleaner much longer. The mineral content, carbon grit, and acid forming compounds in the oil will be much lower. AFC lubricity enhancers will not interfere with crankcase oil additives. Instead, they may actually help them to do a better job.

As in any maintenance situation, the effectiveness of AFC lubricity enhancers does not replace good maintenance practices. However, its use will significantly reduce maintenance requirement and down time, while extending equipment life.

The use of AFC is highly recommended, in particular in situations with low sulfur, or low lubricity fuel. The lubricity enhancer and corrosion inhibitor package in the catalyst are designed to improve engine performance and increase the life of key engine parts while saving in fuel and reducing harmful emissions.

Combustion Catalyst Treatment Ratios

The AFC combustion catalyst compound is the deposit control and combustion surface modifier, which acts as a catalyst breaking down carbon deposits. The deposits are reduced through a process called de-carboxylation, the release of a carbon atom in the form of C02.

The relatively cool surface temperature of the deposit layer restricts de-carboxylation from happening naturally in an internal combustion engine. The catalyst reduces the temperature needed for de-carboxylation from about 600o C to about 200o C. It enables the chemical reaction to occur on the cooler surface of the deposits.

The interaction of the catalyst with the exposed surface of the deposits causes the release of a water molecule and a carbon molecule in the form of CO2. The deposit surface re-oxidizes to a carboxyl state and continues interacting with the catalyst molecules.

The effectiveness of AFC in removing carbon deposits is related to the surface area and mass of the deposits, the amount of new deposit material being formed during combustion and the amount of catalyst present. Results will be different for each combustion chamber because of its unique history of deposit buildup. However, due to the similarity in basic chemical reactions the end result will be the same in spite of all the differences.

Once an old engine is clean, the minimum amount of catalyst needed is the amount required to inhibit new deposit formation. A new engine needs only this minimum amount to remain clean, and a dirty engine will not get any worse. The exact amount in each case depends on the size of the combustion chamber and the fuel being used. The concentration of AFC catalyst in treated fuel is higher than the necessary minimum requirement. It ensures zero new deposit formation, and the complete removal of all old deposits.

The optimum amount to use in a dirty engine is the amount necessary to inhibit new deposit formation plus completely saturate all exposed surfaces of existing deposits. Excess amounts of catalyst beyond the surface saturation point, will not speed up the deposit removal process.

The concentration of the active ingredient has been calculated such that the majority of the dirty engines in operation will receive a sufficient amount of combustion catalyst required for total deposit surface saturation.

NOTICE: The following begins a somewhat more technical discussion on the benefits of, and how AXI Fuel Catalyst, Fuel Stabilizer and Tank Cleaning Additive impacts the diesel engine Combustion Process, handles Combustion Byproducts, Removes and Eliminates Combustion Deposits, Effects SOx, NOx, Low Sulfur Fuels, Fuels that contain Vanadium and Sulfur, and Pour Point & Cloud Point. You may wish to consider this optional information, but it does provide a more in-depth view of the benefits of AFC.

How AXI Fuel Catalyst helps the Combustion Process

The AXI Fuel Catalyst interacts with the heavier, long chain, combustion resistant elements of the fuel, and existing carbon deposits. This interaction allows these deposits to break down and burn. The "molecular atomization" of the fuel, and the destruction and burning of the surface deposits produce the following positive effects on the combustion process:

  • Quicker, more complete combustion

  • Optimal use of available oxygen

  • Lower excess air requirements

  • Removal of existing deposits

  • Better heat transfer

  • Lower fuel consumption

  • Increased overall efficiency

How AXI Fuel Catalyst Effects Combustion Byproducts

AFC-705 enhances the combustion process, which leads to the following positive effects on combustion byproducts:

  • Inhibition of new deposit formation

  • Removal of old carbon deposits

  • Prevention of new deposit formation

  • Decreased fuel consumption

  • Decreased particulate, smoke and soot

  • Decreased NOx, SOx, CO, and VOC emissions

  • Decreased carbon content in the ash

  • Decreased fouling and corrosion due to decrease in V205 activity

  • Decreased cold-end corrosion due to decreased SO3 formation

These effects lead to a significant increase in energy output by burning a larger portion of the Carbon available in fuel, and an important reduction in corrosion due to much lower formation of SO3, which increases the amount of SO2, harmlessly captured in ash.

The Deposit Removal Mechanism

Combustion Deposits are mostly carbon and aromatic compounds in a highly combustion resistant state. These deposits are the source of many engine problems, such as higher than normal fuel consumption, excessive harmful exhaust, and costly maintenance. Fuel problems and incomplete combustion ultimately cause complete engine failure.

Deposit formation begins with spherical molecules called primary particles and branched aromatic chains, both of which are produced in the early stages of combustion. The chain branches consist of alkyl, alcohol, carbonyl and carboxyl compounds. The alkyls oxidize to alcohol, oxidizing to carbonyl, oxidizing to carboxyl. The oxidation process stops with the carboxyl compounds, which are acidic and highly combustion resistant with a high energy of activation.

The various branch compounds are attracted to the primary particles, which spin at extremely high velocities. When a branch becomes attached to a primary particle, the entire chain structure is quickly wrapped around the primary particle forming a secondary particle. These secondary particles agglomerate and form a tertiary particles. This can happen when several primary particles become attached to the same chain on different branches, and then simultaneously become secondary and tertiary particle, as they wrap up the chain.

Tertiary particles agglomerating on a surface will become further coated to form quaternary particle. The coated quaternary particles make up deposits. The chain structures coating the surface of deposits leave exposed branches. It is at these branches where AFC catalyst begins to break down and destroy the deposits as it modifies the surfaces.

The carboxyl branches are acidic, and attract the AFC catalyst oxide which is basic. When the two combine a process called dehydration occurs and a water molecule is produced. What remains is a compound with a low energy of activation, which readily breaks down at high temperatures, releasing a CO2 molecule and the catalyst oxide.

Upon releasing the CO2 and the catalyst oxide, the end of the chain re-oxidizes to an alkyl, alcohol or carbonyl compound and finally to a carboxyl compound. When the end of the chain reaches this state, the catalyst oxide once again combines with the carboxyl, and starts the break down cycle again. Over time, the deposits are removed by being converted to CO2 and water.

AFC inhibits the formation of new deposits in much the same way as it destroys existing deposits. It interacts with the ends of the aromatic chains and the attachment sites on the primary particles. This interaction keeps the primary particles from wrapping up full chains, by blocking or destroying the attachment sites, and/or breaking the chains.

This interference stops the deposit agglomeration process at the primary and/or secondary particle agglomeration state. This results in much lighter and smaller particles that don’t stick together and are more easily oxidized. The result of this interference is a lower mass of particulate emissions, and instead an increased energy output, and increased production of CO2 and water, which are the desirable end products of the combustion cycle.

Deposits are the major source of emissions. Eliminating deposits lowers the production of soot and smoke. The use of AFC enhances energy output and optimizes the production of CO2 and water during the entire combustion process, which significantly lowers the output of both regulated and unregulated emissions.

Eliminating Combustion Deposits

AFC technology is based on the catalytic effects of organo-metalics. The main active ingredients are synergistic, multi-functional combustion catalysts containing combustion surface modifiers and deposit surface modifiers. AFC can be used with any liquid hydrocarbon fuel such as gasoline, diesel, residual fuel and HFO.

In an AFC treated environment, the surfaces of the fuel particles and deposits are modified such that the catalyst lowers the energy of activation of the deposit surfaces. The modified surface deposits can then burn up at a much lower temperature.

A typical engine develops a temperature gradient ranging from 200 deg. C at the combustion chamber wall, to 1200 deg. C in the combustion center. Many of the fuel components require a higher temperature than 600 deg. C to combust. It is not possible to completely burn heavy fuel components in temperatures ranging from 200 deg. to 600 deg. C. Incomplete combustion forms the deposits, harmful emissions, and the consequential mechanical problems.

Combustion chamber deposit surfaces and fuel particles treated with AFC begin to combust at temperatures as low as 200 deg. C and then burn over the entire temperature range. This results in complete combustion and eventually in the total removal of all engine deposits, while at the same time preventing new deposit buildup. Complete combustion leads to better performance, lower fuel consumption, lower emissions (CO, SOx, NOx, HC's and PM-10), lowering operating cost, maintenance and downtime.

The process of deposit removal begins immediately, and can take up to 600 hours or 4,000 miles. The actual time needed depends on operation, history, and age of the equipment. AFC treated fuel completely removes the deposits from fuel injectors, intake and exhaust valves, and other exposed combustion chamber parts of dirty engines, while preventing deposits in new engines.

In older engines the use of AFC treated fuel is even more pronounced than the new ones. The performance of new engines will not degrade and maintenance will remain at a minimum. A gasoline engine will not experience an octane requirement increase.

Fuel treated with AFC Combustion Catalyst burns completely so that new engines stay clean, and older, dirty engines become clean. AFC is the most cost effective way to conserve energy and protect the environment while enhancing performance and engine life.

The Effects of AFC-705 on SOx

The treatment of carbon based fuels with AFC has a significant effect on trace sulfur combustion chemistry. In diesel engines, gasoline engines and open flame applications (boilers) the use of AFC treated fuel will significantly reduce sulfur oxide (SOx) emissions, and related sulfur acid corrosion problems.

AFC does not react with the sulfur in the fuel nor does AFC have any effect on the sulfur content of the fuel. AFC does not effect fuel specifications at recommended treatment levels. Fuel containing one percent sulfur prior to AFC treatment will still contain one percent sulfur after AFC treatment. However, the use of AFC will determine where the sulfur ends up and what its chemical state will be after combustion.

The combustion of sulfur in fuels invariably leads to the formation of sulfur dioxide S + O2 -->SO2 (1) and sometimes sulfur trioxide 2SO2 + O2 -->2SO3 (2). Sulfur trioxide formation is catalyzed by vanadium pentoxide (V5+ ). This is the most stable oxidation product of vanadium, when vanadium containing fuels are burned in air 4V + 5O2 -->2V2O5 (3). The catalytic effect is thought to relate to the reversible dissociation 2V2O5 -->2V2O4 + O2 (4) at temperatures between 700o -1125o C. The sulfur trioxide reacts with water vapor to form sulfuric acid SO3 + H2O -->H2SO4 (5) which is primarily responsible for acid corrosion problems in combustion equipment.

AFC affects the production of gaseous SOx emissions. It enhances the formation of CO2 during the combustion phase thus limiting the amount of SOx produced during the exhaust phase. The increased production of CO2 reduces the amount of excess O2 available for other reactions. The difference in the amount of CO2 produced during the combustion and the exhaust phases correlates to a temperature differential. This temperature differential results in lower exhaust temperatures and shorter heat transfer times.

Minerals contained in fuel are generally oxidized to metal oxides during the combustion process. When vanadium is oxidized to V5+ the production of sulfur trioxide increases due to reversible dissociation, and sulfuric acid is ultimately formed. The use of AFC inhibits the formation and reversible dissociation of V5+ during the exhaust phase by limiting the available O2, high temperatures, and time periods needed for these reactions to occur.

This greatly reduces the catalytic effect V5+ has on the formation of Sulfur trioxide and thus the formation of sulfuric acid. By reducing the catalytic effect of vanadium, AFC promotes the combination of SOx compounds with other minerals in the fuel such as Na and Ni. This leads to the formation of stable mineral salts and mixed mineral sulfates found in the clinker or fly ash.

In this manner, AFC decreases the gaseous sulfur emissions by increasing the particulate portion of the combustion residue products. AFC treated fuels will therefore show slightly higher sulfate content in the ash than untreated fuel.

The Effects of AFC on NOx

The formation of NOx takes when combustion temperatures reach above 2500 deg. F and pressures are the highest. This especially occurs when the engine is under high load or wide open throttle. NOx formation is influenced by available excess oxygen, time, and deposit buildup.

AFC significantly lowers the amount of NOx production in internal combustion engines and open flame boilers.

This reduction correlates with combustion deposit removal. Carbon deposit build up in the combustion chamber causes higher compression. This directly affects the factors responsible for the formation of NOx and supports a direct connection between NOx emissions and deposits. This connection is supported by the fact that clean engines using AFC treated fuel produce very low amounts of NOx. The process by which AFC inhibits the formation of NOx is a direct result of the process by which it removes existing and prevents the formation of new deposits, namely through the promotion of CO2 production.

AFC affects the three main factors enhancing the formation of NOx. Fuel has a finite amount of energy, which is released through the production of CO2. AFC promotes the formation of CO2 during the combustion phase. If more CO2 or energy is produced during the combustion phase then less is available to be released during the exhaust phase. The difference in the amount of energy released during the two phases correlates to a temperature differential. This temperature differential, its magnitude and cause are important for three reasons.

Lower exhaust temperature. If the temperature of the combustion phase rises due to increased CO2 production then the temperature of the exhaust phase will go down. This denies the nitrogen molecules the high temperatures needed to form NOx compounds. Lower temperatures slow down the production of NOx by requiring more time for the reactions to take place. The greater the amount energy released during the combustion phase and the associated lower exhaust gas temperature the lower the rate of NOx production will be.

Shorter heat transfer time. The greater the magnitude of the temperature difference, the shorter the heat transfer time becomes. Increase in heat transfer to the surrounding engine components during combustion will decrease exhaust temperature and time for the conversion of nitrogen to NOx compounds. The shorter the heat transfer time the lower the NOx emissions.

Oxygen depletion. Increasing the production of CO2 uses up more of the available oxygen. AFC promotes the production of CO2 during the combustion phase, lowering oxygen availability for NOx reactions during the exhaust phase. Less available oxygen results in lower NOX emissions.

The combination of lower exhaust temperatures, shorter heat transfer time, less available oxygen, and the complete removal of carbon deposits cause a very significant reduction of NOx emissions.

The Effects of AFC on Low Sulfur Fuels

The sulfur content of diesel fuel became a major concern due to its contribution to SOx emissions, especially SO3, which combined with water forms acid. This led to legislation requiring the removal of all but .05% of the sulfur in all diesel fuel used in over the road applications as of October 1, 1993. Regulations will lower allowable sulfur content even more.

Although sulfur itself does not contribute to the performance of a fuel, the fuel components removed together with the sulfur to produce a low sulfur fuel did. These other fuel components have a BTU value, and give the fuel its lubricating properties. The latter was important since many engine manufacturers used the fuel itself to lubricate the fuel pump and other engine parts that come in contact with the fuel. These same components also provide an important portion of the total energy content of the fuel.

Low sulfur fuels have a lower BTU value, a lower lubricity factor and present significant problems for fuel producers and users alike. In the refining process, considerable amounts of extra work are required to remove the sulfur. The process has resulted in extensive re-tooling of the refinery, which has translated into a significant cost increase for the end user. The result is a lower energy yielding fuel at a higher cost.

Cost increase is not the only problem the end user experiences. There was an immediate drop in fuel economy of about 3 to 7%, and a considerable loss of power resulting from the lower BTU value. Because of the reduced lubricating properties of the fuel vital engine parts would wear out more quickly. This could be noticeable in as little as one or two months. The reduction in lubricity has also contributed to a loss in usable power due to the increased friction the engine must overcome. Even a perfectly tuned engine would experience a noticeable drop in efficiency.

The traditional solution had been to add lubricity and anti-wear additive packages to the fuel. AFC contains a premium lubricity and anti-wear additive package correcting the friction and wear problems.

AFC increases fuel economy of engines, turbines and burners. Lower fuel consumption to obtain the same energy output, immediately translates into lower overall emissions.

AFC keeps the engine clean and free of deposits, which lowers maintenance and operating cost. The lubrication oil of engines using AFC stays significantly cleaner and last much longer. Regardless of the type of fuel used, AFC treated fuel will perform better than non-treated fuel. The results will always be immediately evident.

In all applications, AFC more than pays for itself. It saves money, and enhances your bottom line.

AFC in Fuels Containing Vanadium and Sulfur

Crude oils from Alberta, Canada and from Venezuela contain considerable amounts of dissolved vanadium oxides. Normal refinery practice does not provide for the removal of these vanadium oxides. In fact, a major source of commercial vanadium is derived from the fly ash from burning Canadian crude.

In an engine where there is no catalysis for the fuel combustion, unused oxygen can cause the vanadium (oxidation state of three) to be oxidized to vanadium pentoxide, V2O5. This V2O5 can be a problem in itself because it deposits as a hard coating on the surface on the combustion chamber walls. Under many circumstances it has to be manually chiseled off.

If an engine is already damaged by vanadium deposits (V2O5) it is unlikely that AFC can burn off these deposits. Whereas, if the deposits were carbon, adding AFC to the fuel will definitely burn off these carbon deposits.

In addition, the presence of V2O5 can catalyze the transformation of sulfur dioxide, SO2, to form sulfur trioxide, SO3. This is important because sulfur trioxide (SO3) and water gives the highly corrosive sulfuric acid.

Since water is one of the products of hydrocarbon combustion, much damage occurs to all metal parts of the combustion chamber and the exhaust system, resulting from the acid that is produced when vanadium is in the fuel.

The use of AFC results in the complete use of the oxygen present in combustion, leaving little or no oxygen to oxidize the mixed vanadium oxides to the V2O5. By using up all the available oxygen to burn the fuel completely, there is little or no oxygen left over to oxidize the SO2 to SO3 whether V2O5 is present or not.

In new engines and boilers, the use of AFC, will significantly diminish the formation and deposits of V2O5, and therefore prevent production of SO3 and the resultant acids. This clearly and significantly diminishes engine damage caused by acidic corrosion.

As a result, engine life and overhaul cycles will be dramatically extended, while engine maintenance, down time, and overall cost of operations will be significantly reduced. The cost of AFC is more than justified on the basis of its effect on preventing the oxidation of the vanadium oxides and sulfur which are very difficult to remove from fuels.

Pour Point and Cloud Point

The pour point is the lowest temperature at which a petroleum product will begin to flow. Pour point is measured at intervals of 5o F. This interval gives a range in which to account for error inherent in the measuring procedure. A sample with a pour point of 10.5o F and a sample with a pour point of 14.5o F would be labeled as having a pour point of 15o F. Even with the 4o difference they would be considered the same. However, a sample with a pour point of 15.5o F would be labeled as having a pour point of 20o F even though it is only 1o higher than the 14.5o F sample mentioned before. Due to experimental and operator error, sample variations of one interval are not considered significant. Since the measured values for the two samples are only one interval apart the difference is not significant.

The cloud point is the temperature at which wax crystals begin to form in a petroleum product as it is cooled. Cloud point is measured at intervals of 2o F. An example similar to the one used illustrating the pour point procedure applies here. Differences of one interval are not considered significant. Wax crystals depend on nucleation sites to initiate growth. The difference in the cloud points of the two samples is explained by the fact that any fuel additive will increase the number of nucleation sites, which initiate clouding. A change in temperature at which clouding starts to occur is therefore expected upon addition of any additive. The difference between the cloud point values for the two samples is not abnormal and is not significant.

AXI Fuel Catalyst -- An Alternative Technology

An average reduction of five (5) to ten (10) percent in the consumption of petroleum based fuels by engines that have not historically and periodically been treated with a fuel system cleaner is realistic and a very significant reduction of emissions is possible. All we need to do is treat our fuel with AXI Fuel Catalyst 705 or 710.

AFC contains a multi component combustion catalyst, which promotes the removal of engine deposits especially those in the combustion chamber. While removing deposits, AFC treated fuel burns cleaner and more completely, thus eliminating the formation of new deposits. New engines stay clean and older engines become clean. Initially the use AFC treated fuel will often show reductions in fuel consumption far greater than the average five (5) to ten (10) percent. The reduction of emission will increase with the removal of the existing deposits.

In addition, the use of AFC treated fuel will significantly lower equipment operating and maintenance costs, while engine life can be more than doubled. There is less wear on the engine parts and engine oil stays cleaner much longer. When disassembling an engine, a simple wipe down with a shop cloth will show that the parts look as good as new, often with all the serial numbers clearly readable and machining marks still clearly visible.

AFC is extremely cost effective technology. This complete additive package improves fuel consumption and reduces emissions. It extends engine life, decontaminates and cleans the total fuel system, dissolves tank sludge, lowers operating and maintenance cost, while enhancing your bottom line. The AFC additive package perfectly complements magnetic fuel conditioning.
