Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process.
Brazil's sugar cane-based industry is more efficient than the U.S. corn-based industry. Sugar cane ethanol has an energy balance seven times greater than ethanol produced from corn. [2] Brazilian distillers are able to produce ethanol for 22 cents per liter, compared with the 30 cents per liter for corn-based ethanol. [151]
The production of ethanol from sugarcane is more energy efficient than from corn or sugar beets or palm/vegetable oils, particularly if cane bagasse is used to produce heat and power for the process. Furthermore, if biofuels are used for crop production and transport, the fossil energy input needed for each ethanol energy unit can be very low.
These raw materials for ethanol production have the advantage of being abundant and diverse and would not compete with food production, unlike the more commonly used corn and cane sugars. [2] However, they also require more processing to make the sugar monomers available to the microorganisms typically used to produce ethanol by fermentation ...
The Saab 9-3 SportCombi BioPower was the second E85 flexifuel model introduced by Saab in the Swedish market. Ethanol fuel is fuel containing ethyl alcohol, the same type of alcohol as found in alcoholic beverages. It is most often used as a motor fuel, mainly as a biofuel additive for gasoline. Several common ethanol fuel mixtures are in use ...
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...
Ethanol fuel production by state. The United States became the world's largest producer of ethanol fuel in 2005. The U.S. produced 15.8 billion U.S. liquid gallons of ethanol fuel in 2019, and 13.9 billion U.S. liquid gallons (52.6 billion liters) in 2011, [1][2] an increase from 13.2 billion U.S. liquid gallons (49.2 billion liters) in 2010 ...
The history of ethanol fuel in Brazil dates from the 1970s and relates to Brazil 's sugarcane -based ethanol fuel program, which allowed the country to become the world's second largest producer of ethanol, and the world's largest exporter. [1] Several important political and technological developments led Brazil to become the world leader in ...
