In the next few weeks, the Obama administration is nexpected to approve a request by a coalition of renewable-nfuel companies to allow a higher percentage of ethanol to be nblended into gasoline.Beth EvansPlatts Inside Energy
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 phas...
and the relevant authorities are interested in further increasing the bio-ethanol content in gasoline. Blending bio fuels with a petroleum-based fuel has furthermore the twin advantages that even relatively small percentage additions will result in a substantial total volume of gasoline substitution, an...
Although the emission of aldehyde will increase when we use ethanol as a fuel, the damage to the environment by the emitted aldehyde is far less than that by the poly-nuclear aromatics emitted from burning gasoline. Therefore, higher percentage of alcohol in blended fuel can make the air ...

Bioethanol from sugar cane, produced under the proper conditions, is essentially a clean fuel and has several clear advantages over petroleum-derived gasoline in reducing GHG emissions and improving air quality in metropolitan areas. However, there remains a compromise between GHG emission and saving ...
Nowadays, the gas you pump from almost every gas station contains a blend of gasoline and ethanol. The percentage of ethanol blend is indicated by the E number. For example E10 means the gas mixture contains 90% gas and 10% ethanol. In automobiles, ethanol fuel won’t do much harm to ...
reducing emissions from road traffic is the use of alternative fuels. Alternative fuels are derived from resources other than petroleum. Some are produced domestically, reducing dependence on foreign oil and some are derived from renewable sources. Alternative fuels produce less pollution than gasoline ...

decreases GHG emanations by 12% as compared with gasoline (Hill et al.2006). Therefore, it has been used in the concentration range of 10–85% (v/v) for the gasoline mixture (Vohra et al.2014). Ethanol manufactured by fermentation occupied by over 90% in the ethanol industry (Zi et ...
