MMT as a fuel additive
Description
MMT® Fuel Additive
MMT® (Methylcyclopentadienyl Manganese Tricarbonyl) Fuel Additive is a thermally stable liquid developed by Afton Chemical (formerly Ethyl Petroleum Additives, Inc.) in the 1950s. It is an organic manganese compound that is easy and safe to handle, and compatible with all fuels. MMT® is used at very low treat rates (ppm level); just a few drops added per gallon of gasoline can increase octane by 1 or 2 octane numbers. It has been utilized for over thirty years as an efficient octane improver in unleaded gasoline and in every application has a well-proven record of acceptable performance in consumer use. Commercially, it is available as HiTEC® 3000 Octane Improver.
MMT® helps the refiner keep the cost of petrol (gasoline) low while meeting stringent environmental and fuel quality specifications. Refining and blending economics are greatly improved by allowing more efficient unit operation and blending of lower cost components. Significant savings can be achieved compared to other commonly used octane solutions. The use of MMT® permits refiners to beneficially alter fuel composition, both reducing emissions and energy consumption at the refinery and producing a cleaner burning gasoline. MMT® also helps vehicles maintain their emission performance over their useful life by protecting catalysts and oxygen sensors from degradation caused by poisons such as phosphorus from the lubricating oil.
Much is known about manganese and its potential impact on public health, whether due to use of MMT® or from other industrial uses of manganese. MMT® is one of the most comprehensively tested fuel additives in history. Through repeated evaluation, MMT® has demonstrated no identifiable risk to public health or welfare. The use of MMT® Fuel Additive has been reviewed by government agencies and approved for use around the world. Over 150 refiners in 45 countries in Europe, Africa, Asia, Central and South America, as well as the United States and Canada, currently use MMT® to produce high quality gasoline, providing fuel for millions of cars with over a trillion miles of trouble free operation.
