Ethanol is commonly known as alcohol. It is a kind of new and alternative energy source, which is made from the mixture of fuel ethanol and regular gasoline with a certain proportion. According to the national standard of China, ethanol gasoline is made by 90% of regular gasoline and 10% of fuel ethanol.
Ethanol can effectively improve the performance and quality of the oil, as well as reduce the discharge of the major pollutants, such as carbon monoxide, hydrocarbons, and so on. Ethanol not only does not affect the driving performance of the car, but also can reduce the emission of harmful gases. Ethanol gasoline, as a new type of clean fuel, is the focus of the development of renewable energy in the present world. It is in line with the alternative energy strategy and the development direction of renewable energy of China. Being technologically mature and reliable, ethanol gasoline is fully applicable in our country, which has good economic and social benefits.
Ethanol gasoline is very beneficial to our environment, so people think highly of this kind of new, clean and renewable energy source. According to the survey in nine cities, during the period when using ethanol gasoline instead of other traditional petrol, the air pollutants in the city atmosphere have been greatly reduced. For example, during one season, the amount of nitrogen dioxide has been reduced by 8%, and the amount of carbon monoxide has been reduced by 5%.
Early in the 1920s, Brazil first began to use ethanol gasoline. Because Brazil lacks of oil resources, but rich in sugar cane, so it developed a set of technologies of producing sucrose and alcohol from sugar cane. At present, Brazil is the largest country in the world in the utilization of ethanol gasoline, in which the ethanol has reached 20%.
Most provinces and cities in China also begin to use ethanol gasoline, which has accounted for a large proportion in the total sales of gasoline, and the ratio still keeps increase. However, because of materials, cost and technical issues, China has ever encountered some obstacles in the promotion of ethanol gasoline. Later, thanks to policy support and technical advancement, the promotion of ethanol gasoline has been improved a lot. On the whole, the utilization and promotion of ethanol gasoline is an irresistible trend of China. During the period from 2006 to 2010, the vehicle ethanol gasoline will be promoted in much more areas in the domestic country.
