REC-90 is an ethanol-free, 90 octane unleaded gasoline blend designed for use in recreational/marine engines which can be damaged by the ethanol found in other gasoline blends. It is also usable in some aviation engines [ 1 ] and automotive engines, though it has not been thoroughly tested for cars and trucks.
Ethanol fuel specifications worldwide traditionally dictate use of anhydrous ethanol (less than 1% water) for gasoline blending. This results in additional costs, energy usage and environmental impacts associated with the extra processing step required to dehydrate the hydrous ethanol produced via distillation (3.5-4.9 vol.% water) to meet the ...
However, the fuel systems of cars, trucks, and motorcycles sold before the ethanol mandate may suffer substantial damage from the use of 10% ethanol blends. Flexible-fuel cars, trucks, and minivans use gasoline/ethanol blends ranging from pure gasoline up to 85% ethanol . By early 2013 there were around 11 million E85-capable vehicles on U.S ...
The EPA has approved sales of E15 for cars and trucks manufactured after 2000. The RFA estimates that the higher blend will cost consumers more than 25 cents a gallon less than 10% ethanol.
Butanol better tolerates water contamination and is less corrosive than ethanol and more suitable for distribution through existing pipelines for gasoline. [15] In blends with diesel or gasoline, butanol is less likely to separate from this fuel than ethanol if the fuel is contaminated with water. [15]
Typical Brazilian filling station with four alternative fuels for sale: biodiesel (B3), gasohol (E25), neat ethanol , and compressed natural gas (CNG). Piracicaba, São Paulo, Brazil. Alternative fuels, also known as non-conventional and advanced fuels, [1] are fuels derived from sources other than petroleum. [2]
The issue could hurt the biofuel industry, which sees SAF as ethanol’s best chance at growth since electric cars have cut into its market as a gasoline additive. Little to no ethanol will ...
This shift also contributed to a sharp increase in the production and sale of E85 flex vehicles since 2002. [19] Ethanol also replaces toxic, air-polluting substances such as benzene, toluene, and xylene. Numerous states require certain ethanol blends to reduce air pollution. Ethanol produces about 34% less air pollution than gasoline on ...
