What Is Ethanol Biofuel?

Bioethanol refers to the conversion of various biomass into fuel alcohol through the fermentation of microorganisms. It can be used alone or mixed with gasoline to make ethanol gasoline as a car fuel.

Bioethanol

Gasoline doped with ethanol has two functions: one is that the octane number of ethanol is as high as 115, which can replace the pollution

In September 2007, the OECD published a book entitled "Biofuels: Is It Worse Than A Disease? A long report arguing that the development of biofuels has outweighed the benefits, and called on the United States and European countries to cancel their current subsidies for biofuels. OECD "Sustainable Development"

At present, ETBE (Ethyl Tertiary Butyl Ether) is used as a substitute for bioethanol in the world.

Japan has successfully developed a new technology that can use low-cost, high-yield straw to produce bioethanol. ^[2]

Under normal circumstances, the starch in the straw is difficult to dissolve in water. Therefore, the existing technology mainly uses cellulose in the straw to produce ethanol, and the starch has not been effectively used. The technician added a special alkaline solution to the straw material and confirmed that the starch can be fully dissolved in the alkaline solution. Then, the dissolved starch is converted into sugar by using a production process different from cellulose. ^[2]

Japan's experimental production equipment has been able to produce 315 liters of ethanol from 1 ton of dry straw. Compared with the use of original technology and equipment, the output has increased by more than 24%, and the cost has also fallen to 70.7 yen (about 0.7 US dollars) ). ^[2]

Bioethanol has become an important clean fuel in the United States, Brazil and other countries, but currently bioethanol is basically produced by food crops such as corn, which often conflicts with food security and is not sustainable. ^[2]

According to research by the University of Adelaide, the Mexican desert plant agave is expected to become a source of biofuels and other biochemical products. Researchers at the Australian Research Council's Plant Cell Wall Center of Excellence have found that agave plants can produce up to 15,000 liters of biofuel per hectare per year, and that it can grow on barren land under low rainfall.

Researchers are looking for the best cultivation methods for ethanol production, such as using planting density and mechanization to maximize yield and optimize fermentation. Agave plants produce large amounts of sugar and are easily fermented into bioethanol. Researchers have modeled ethanol production, predicting that 4000 to 15,000 liters of ethanol can be produced per hectare of plant per year.
