China becomes the third largest producer of fuel ethanol

The Chinese biomass energy industry is developing rapidly. Up to now, China has become the world's third largest producer of fuel ethanol, and the biodiesel industry, which uses waste oil as raw material, has also achieved large-scale industrial production. This is the information that the reporter learned from the 2nd International Conference on Biomass Energy Technology held in Beijing on August 20-23.

Ouyang Pingkai, academician of the Chinese Academy of Engineering and president of Nanjing University of Technology, pointed out that fuel ethanol and biodiesel are the two most widely used biofuels in the world. Following the United States and Brazil, China has become the third largest fuel ethanol producer in the world. However, the issue of food security limits the increase in the production of fuel ethanol in China. Therefore, the Chinese government and enterprises are fully developing non-grain ethanol fuels such as corn straw, cassava and sugarcane bagasse, and an annual output of 200,000 tons of cassava fuel ethanol plant has been completed and put into operation in Guangxi. The annual output of 10,000 tons of corn straw fuel ethanol plant is also It will be established next year.

Academician Yan Enze, an academician of the Chinese Academy of Sciences and the Chinese Academy of Engineering and a member of both the Chinese Academy of Engineering and the Petrochemical Research Institute of Sinopec, pointed out that the key to the development of the biodiesel industry lies in the selection of raw materials. Different from the European Union's choice of rapeseed oil and the United States' choice of soybean oil, China chose to use waste waste oil as raw material to produce biodiesel, and has developed three process routes of conventional acid-base catalysis, subcritical state catalysis and enzyme catalysis. All achieved industrial production. Ouyang Pingkai also said that about 20 million tons of waste oil in China each year promotes the rapid development of biodiesel.

In addition, according to Prince Wang of Beijing University of Chemical Technology, apart from fuel ethanol and biodiesel, China has also made significant progress in biogas, biomass power generation, biomass gasification, biomass particles and other fields. China's biomass energy industry is beginning to take shape. .
