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 has a "gasoline gallon equivalency" (GGE) value of 1.5, i.e. to replace the energy of 1 volume of gasoline, 1.5 times the volume of ethanol is needed. [4] [5] Ethanol-blended fuel is widely used in Brazil, the United States, and Europe (see also Ethanol fuel by country). [2]
TCX can function as a fuel additive to operate vehicles and in industrial-grade applications to manufacture paints, coatings, inks and pharmaceuticals. [6] It is intended for use in countries or regions wanting to lessen dependence on imported energy and with easy access to plentiful hydrocarbons.
Scientific evidence reveals that water is an inhibitor for corrosion by ethanol. [6] The experiments are done with E50, which is more aggressive and speeds up the corrosion effect. It is very clear that by increasing the amount of water in fuel ethanol one can reduce corrosion. At 2% or 20,000 ppm water in the ethanol fuel the corrosion stopped.
This industrial plant is set up to produce sugar, ethanol fuel (both anhydrous and hydrous), industrial grade ethanol, and alcohol for beverages. The foreground shows the receiving operation of the sugarcane harvest, immediately followed by the mill process, and in the right side of the background is located the distillation facility where ...
Summary of the main ethanol blends used around the world in 2013. Several common ethanol fuel mixtures are in use around the world. The use of pure hydrous or anhydrous ethanol in internal combustion engines (ICEs) is only possible if the engines are designed or modified for that purpose, and used only in automobiles, light-duty trucks and motorcycles.
Overall, 94% of ethanol in the United States is produced from corn. [5] Currently, corn ethanol is mainly used in blends with gasoline to create mixtures such as E10, E15, and E85. Ethanol is mixed into more than 98% of United States gasoline to reduce air pollution. [5] Corn ethanol is used as an oxygenate when mixed with gasoline.
The ethanol-powered "flex" vehicles, as they are popularly known, are manufactured to tolerate hydrated ethanol , an azeotrope composed of 95.6% ethanol and 4.4% water. [ 21 ] The Honda CG 150 Titan Mix was launched in the Brazilian market in 2009 and became the first mass production flex-fuel motorcycle sold in the world.
