Alcohol yield from various feedstocks

Posted by Krzysztof Lis on December 16, 2011

Below you will find a table representing 199+ proof (99,5%+) alcohol yield from various feedstocks. The values are both in US gallons per ton (2,000 lbs) or litres per metric tonne of feedstock. The numbers were obtained from calculation of the amount of fermentable substances contained in the feedstocks. As you can imagine, real values will be noticeably lower.

It doesn’t surprise that the best feedstock for ethanol production is the wheat, along with other grains, like corn and buckwheat. Raisins and prunes work great as they’re dried, and thus contain a lot of sugar per unit mass. WAIT! There is more to read… read on »

Is ethanol really an alternative fuel?

Posted by Krzysztof Lis on November 18, 2011

In the vast amount of information about alternate energy, there a lot of sources of alternate energy that are really not as effective as they are promising to be. Some of these energy sources are much hyped and marketed because the interest in alternate energy is conducive for investor interest in the process. The hype can be a quick source of earning money for alternate energy fraudsters.

Therefore, although it is safe to invest money in established alternate energy solutions, especially solar panels, because the government is spending billions to foster their development, one should be careful before spending money and thought on miraculous alternate energy solutions like ethanol. A common notion that has been slowly gaining ground is that biofuels like ethanol can offer a long term solution to America‚Äôs fuel crisis and provide substantial returns to investors. This notion, although technically true, yet has several real life obstacles facing it before it turns into a successful alternative to gasoline. WAIT! There is more to read… read on »

Ethanol as an engine fuel

Posted by Krzysztof Lis on March 18, 2008

When Otto invented his first internal combustion engine in 1872, people didn’t know how to refine (distillate) crude oil. Because of that, no petroleum-derived fuel were available at that moment. So Otto used spirit (90-95% alcohol, or 180-190 proof) as a fuel for his engine. Ford T’s engine was able to work on gasoline, spirit or any mixture of those two substances. Even now, alcohol is quite a good fuel for spark ignition or even compression ignition (diesel) engines. WAIT! There is more to read… read on »
