There are three general categories of ethanol-gasoline blends: E10, E15, and E85. E10 is gasoline with 10% ethanol content. Most of finished motor gasoline sold in the United States is E10. E15 is gasoline with 15% ethanol content, and E85 is a fuel that may contain up to 85% fuel ethanol.
6 Αυγ 2016 · Ethanol is a cleaner fuel than gasoline, and it helps reduce emissions when mixed with gasoline. Plus the plant products used to make ethanol absorb some carbon dioxide as they grow.
In the U.S, ethanol fuel is mainly used as an oxygenate in gasoline in the form of low-level blends up to 10 percent, and, increasingly, as E85 fuel for flex-fuel vehicles. [4] The U.S. government subsidizes ethanol production. [5] [6]
Ethanol Fuel Basics. Ethanol is a renewable fuel made from various plant materials collectively known as " biomass." More than 98% of U.S. gasoline contains ethanol to oxygenate the fuel. Typically, gasoline contains E10 (10% ethanol, 90% gasoline), which reduces air pollution.
The general chemical formula for alcohol fuel is CnH2n+1OH. Most methanol is produced from natural gas, although it can be produced from biomass using very similar chemical processes. Ethanol is commonly produced from biological material through fermentation processes.
