Until 2005 Brazil was the world's top producer of ethanol fuel when it was surpassed by the United States. Together both countries were responsible in 2011 for 87.1% of the world's ethanol fuel production. [1] In 2009 Brazil produced 27.5 billion liters (7.26 billion U.S. liquid gallons), [13] representing 35.9% of the world's total ethanol ...
The fraction of water that an ethanol-gasoline fuel can contain without phase separation increases with the percentage of ethanol. [29] For example, E30 can have up to about 2% water. If there is more than about 71% ethanol, the remainder can be any proportion of water or gasoline and phase separation does not occur.
Legislation requires retailers to label fuels containing ethanol on the dispenser, and limits ethanol use to 10 percent of gasoline in Australia. Such gasoline is commonly called E10 by major brands, and it is cheaper than regular unleaded gasoline.
World production of ethanol in 2006 was 51 gigalitres (1.3 × 10 10 US gal), with 69% of the world supply coming from Brazil and the U.S. [18] Brazilian ethanol is produced from sugarcane, which has relatively high yields (830% more fuel than the fossil fuels used to produce it) compared to some other energy crops. [101]
The 15% ethanol fuel is cheaper at the pump, but could lead to expensive car repairs and void your warranty. ... E15 is a dime or so cheaper than ordinary fuel at the pump, stretches gasoline ...
Alternative fuel including gaseous fuels such as hydrogen, natural gas, and propane; alcohols such as ethanol, methanol, and butanol; vegetable and waste-derived oils; and electricity. These fuels may be used in a dedicated system that burns a single fuel, or in a mixed system with other fuels including traditional gasoline or diesel, such as ...
A dish of ethanol aflame. Various alcohols are used as fuel for internal combustion engines.The first four aliphatic alcohols (methanol, ethanol, propanol, and butanol) are of interest as fuels because they can be synthesized chemically or biologically, and they have characteristics which allow them to be used in internal combustion engines.
In 2006 the U.S. produced 18.4 billion liters (4.86 billion gallons), closely followed by Brazil with 16.3 billion liters (4.3 billion gallons), [17] producing together 70% of the world's ethanol market and nearly 90% of ethanol used as fuel. [125] These countries are followed by China with 7.5%, and India with 3.7% of the global market share ...
