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 y...
Is ethanol really more eco-friendly than gas? By: Julia Layton An Enterprise car rental employee gases up a Chevrolet with E85 flex-fuel in Washington, D.C. More eco-conscious consumers are demanding cars with higher gas mileage from auto rental companies. See more pictures of AFVs. Chip...

In its current status as a low-percentage fuel additive, the benefits of ethanol are obvious. Since ethanol contains a lot of oxygen in its chemical structure, it burns pretty cleanly. Added in small amounts (typically one part ethanol, nine partsgasoline) to the gasoline that fuels ourcars,...

When ethanol reacts with sodium metal ,it forms sodium ethoxide (C(2)H(5)O^(-)Na^(+)) and hydrogen gas is released .The reaction is as follows. 2C(2)H(5)OH+2Nato2C(2)H(2)O^(-)Na^(+)+H(2)uarr So the gas is hydrogen gas that is evolved during the reactio

Assays were carried out at 40 °C and 1200 rpm using 4.0 g/L rBxTW1-E495A, 20 mM vanillin, 40 mM donor, and 10% ethanol as co-solvent. Reaction time was increased in comparison to the former screening assays to assess the formation of product at 4 and 16 h. Product...
It’s the first commercial-scale facility that can make jet fuel with ethanol, and it has a capacity of about 9 million gallons annually. So we would need about 10,000 of those plants to meet global demand—a somewhat intimidating prospect. Read more in my write-up here. From cow burps...
