Detailed explanation-1: -Denaturants are added to ethanol to make fuel ethanol undrinkable. In the United States, nearly all fuel ethanol is produced from corn kernel starch, which is considered a conventional biofuel under the U.S. Renewable Fuel Standard Program (RFS).
Detailed explanation-2: -Corn stover refers to stalks, leaves and cobs that remain in fields after the corn harvest. This biomass can be used in producing ethanol. Corn stover is the primary biomass source being used for producing cellulosic ethanol in the United States (Wilhelm et al. 2007).
Detailed explanation-3: -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.
Detailed explanation-4: -Ethanol is a high-octane, clean-burning renewable fuel that’s added to gasoline to improve air quality, engine performance and environmental impact. It’s primarily made from field corn, much of which is grown in Nebraska.
