Ethanol gasoline will be promoted in an orderly manner to reduce pollution and improve energy security

The State Council executive meeting held on August 22 this year decided to expand the promotion and use of ethanol gasoline for vehicles in an orderly manner. In addition to 11 pilot provinces such as Heilongjiang, Jilin, and Liaoning, this year, my country will further promote ethanol gasoline in 15 provinces including Beijing, Tianjin, and Hebei.

Currently, 20%-30% of my country's fuel ethanol raw materials come from cassava, and the remaining 70% comes from corn. In 2020, China's gasoline consumption is expected to reach 130 million tons, requiring 13 million tons of fuel ethanol.

Now, the process of producing ethanol has changed from stale grain to corn stalks. There are many suppliers from abroad, including domestic sweet potatoes and imported cassava to produce ethanol. After this kind of ethanol is produced, it will not compete with the people for food like the original stale grain.

Among the new batch of regions in the country that are promoting ethanol gasoline, Tianjin has already started promoting the use of ethanol gasoline for vehicles at the end of August, and will achieve closed operation throughout the city by the end of September.

Ethanol gasoline is a relatively environmentally friendly product. Compared with ordinary gasoline, ethanol gasoline can reduce nitrogen oxide emissions by about 13%.

At present, the proportion of ethanol gasoline in the world has reached 60%, and in some countries, the proportion of ethanol added to each liter of gasoline has even reached 27%. After China promotes ethanol gasoline, it can not only reduce the emission of pollutants such as PM2.5, but also reduce my country's dependence on imported crude oil.

Currently, imported crude oil accounts for more than 70% of annual consumption. If we use alcohol to replace part of the gasoline, we can improve our energy independence.

The calorific value of ethanol is indeed lower than that of gasoline. The calorific value of ethanol mixed with 10% is about 3.8% lower than that of pure gasoline. However, due to the increase in oxygen content in the mixed fuel, the combustion will be more complete and the heat can be increased by 2.3%. Overall, the use of ethanol gasoline only brings a small loss of power, which is basically not noticeable to car owners.

The long-term promotion and use experience at home and abroad has proved that it is not necessary to modify the vehicle when filling and using ethanol gasoline according to the specified brand. When using ethanol gasoline for vehicles for the first time, most vehicles can be used normally without cleaning the oil circuit.
