Green Fuel Catalyst is based on a patented Fitch® catalyst technology and is used in various industries, such as Marine, Power & Heat Generation, Mining & Construction, Automotive and Military for treating hydrocarbon liquid fuels or natural gas. Catalyst has several types of certificates, tests and approved inspection reports from various entities, such as ABS, UL, Lloyd’s, Det Norske Veritas to name a few.

Industries we serve


Catalyst contains no fuel additives, no moving parts, no magnets, no electrical hook-ups, and requires no extra maintenance. Because Catalyst does not participate in the reaction it is not consumed.

When installed in the fuel line after the fuel filter before the engine or combustion chamber, Green Fuel Catalyst immediately reduces both, fuel consumption, carbon footprint, and emissions by reversing naturally occurring fuel degradation improving fuel quality and combustion.

Catalyst is for a permanent hydrocarbon fuel treatment and is manufactured, designed and produced by Advanced Power Systems International (APSI Inc.) in the United States. Catalyst transforms hydrocarbon fuel molecular structure back to its refinery state quality (highest energy density) just before combustion reaction takes place, allowing to extract maximum energy from the fuel while simultaneously minimizing greenhouse emissions and carbon footprint.

Catalyst on average reduces fuel consumption by over 2% and has a robust Return on Investment (ROI) averaging within a 4-6 month range.

Catalyst reverses the unwanted fuel bio-degradation while enhancing olefin formation and selective oxidation of all fuel oils and propane.

Unwanted fuel Oxidization (degradation) begins the day fuel leaves refinery and continues until the time it is combusted. Oxidization causes fuel quality to deteriorate, reducing the amount of useful energy that can be extracted from the fuel. At the same time, the oxidized fuel also increases pollution and residue due to incomplete combustion.
Oxygenation takes place at combustion, and by adding oxygen to the combustion process more useful energy is created meaning less fuel is needed to do the same work.
The presence of the Green Fuel Catalyst enhances the Oxygenation and stabilizes hydrocarbon fuels.

Catalyst is approved by Lloyd's Register, Det Norske Veritas, American Bureau of Shipping (ABS), Underwriters Laboratories (UL) and has various other inspection certificates. Catalyst has also been featured in various scientific journals and magazines and has undergone extensive research tests performed by the University of Connecticut (UCONN), CT, USA scientists while partly funded by the US Department of Energy (DOE) and Defense. 

The manufacturer of the Catalyst entered into a Research Agreement with the U.S. Department of Defense (DOD) to extend the capabilities of the Catalyst to fuels used by DOD, namely diesel and JP fuels. In this program, Catalyst successfully improved diesel fuel fulfilling the technical requirements outlined in the DOD Policy Guidelines. This rigorous program evaluated the impact of the technology on fuel as well as the impact on engines and burners while using fuel treated by the Catalyst. Catalyst also was Shock tested by the Military, pressure tested to 600 PSI (40 bar) according to the US Coast Guard Specifications and as such is US Coast Guard accepted.
