It is a year ago, fuel alcohol is extremely red still temporarily but second birth the sources of energy.
According to U.N. the sources of energy the organization is evaluated for many times, the large-scale exploitation that tellurian oil reserves experiences 40 years or so again will tend dried up, if be not searched,replace resource newly, can reach relevant industry to produce tremendous effect to traffic carrying trade not only, the petrifaction industry that is raw material with ethylene also will become ” of “ cook a meal without rice. Below this kind of setting, fuel alcohol regards a kind of reproducible as circular resource and be tried to value, think it is a kind of burgeoning the sources of energy not only, still can produce ethylene, the petrifaction industry of ” of times of the oil after the “ that prop up, become this century burgeoning base industry.
Foreground happening changes
However, today, the foreground of fuel alcohol had had delicate change. A lot of people think, producing corn fuel alcohol is one of germ that bring about food to rise in price. In the meantime, return somebody to think, the sources of energy that production fuel alcohol wastes replaces the more that fuel can offer than this kind.
The United States almost all biology fuel alcohol are raw material with corn. Show according to data, producing fuel alcohol for raw material with corn is the production means that a kind of need expends a large number of the sources of energy. Produce the sources of energy of 1 caloric biology, need wastes the energy of about 4 calorie, and these energy come from mineral fuel normally, that is to say, the carbohydrate of every 100 calorie in corn, need uses up about 400 calorie to come from coal, natural gas or petrolic energy, these energy are used up was in manufacturing chemical fertilizer, cultivate, results, treatment and carry wait for many link.
More energy-saving new technology
According to the United States " MIT technology is commented on " the magazine reported recently, to allow the producer style of corn fuel alcohol can more energy-saving, the researcher of American Washington university is exploring a kind of new technology, draw lessons from a kind of production methods that winery and institute of plant of liquid waste processing use namely, fermenting origin nature is with organic waste material in the process obtain the fermenting with oxygen little content boiler.
The main and academic basis of this kind of new technology is, when the bacterium decomposes flotsam, it can release a methane, and methane can be returned centrally again through the system, think the factory provides the sources of energy that production uses. This one craft needs very few energy to be able to keep normal movement only, can produce the sources of energy in producing a course with reducing energy cost further. The research group that with Washington university chemistry Largus Angenent of engineering department professor heads had been in ethanol plant to undertake for heart thing with litter oxygen of be disgusted with ferments experiment, the result makes clear, the natural gas dosage of 50% is saved in should be versed in skill produces a course in alcohol quite. This group has published positive result of this one research in latest issue of United States " environmental science and technology " on the magazine.
