Ethanol made from corn starch sources requires a sizable amount of farmland resources as close to two-thirds of the total corn cultivated is dedicated to produce ethanol for biofuel and animal distillers grains [refer to National Corn Growers Association].
In other words it requires close to 60 million acres of farmland dedicated mainly for ethanol production in order to manufacture around 15 billion gallons of ethanol per year, which is about the amount needed to fulfill ethanol as a 10 % by volume fuel additive to gasoline. It is claimed that ethanol is needed as an oxygenated fuel additive in order to raise the octane number of the fuel and reduce carbon monoxide emissions.
In addition, world wide organizations have asserted that corn production in the United Stated for the main purpose of providing it as a fuel additive to gasoline has caused world food prices to rise dramatically and has also contributed to world food shortages. It is asserted then that the US should come up with alternative renewable fuel production methods that would not compete with the food supply but also be energy efficient in method too.
This essay is dedicated to show that there are alternative alcohol production methods available not only for ethanol but also for higher molecular weight alcohols.… Read More
