China's fuel ethanol production started in 2002. After just a few years of growth, it has developed into a large-scale, long-term industry. In 2007, China's four large-scale fuel ethanol production companies sold 1.333 million tons of fuel ethanol, including 419,000 tons of Jilin fuel ethanol, 402,000 tons of Henan Tianguan, 349,000 tons of Anhui Fengyuan, and 162,000 tons of COFCO. With the exception of Tianguan, which uses wheat as a raw material, the other three use corn as a raw material. China's first approved non-grain fuel ethanol company Guangxi Zhongliang Biomass Energy Co., Ltd. has started production at the beginning of this year. With cassava as the main raw material, it has produced more than 20,000 tons of fuel ethanol in the first half of the year.
It is understood that China's ethanol gasoline is currently being promoted in 10 provinces, of which 6 provinces are closed to operation, and another 4 provinces are using 27 cities. One of the reasons why there is no large-scale use in China is that the standards are not complete. So far, the country has only introduced two product standards related to fuel ethanol products, namely the modified fuel ethanol standard GB18350 and the vehicle ethanol standard GB18351; from the implementation point of view, these two standards still need to be improved.
Ethanol production is a traditional industry, but fuel ethanol production is a new industry. Due to the scarcity of petroleum resources, China has vigorously developed biomass energy. The consumption of fuel ethanol appears to be increasing wheat, corn, and other foodstuffs. The high cost of raw materials has resulted in losses for the company. Last year, the Ministry of Finance formulated the "Financial Financial Management Measures for Flexible Rejection of Biofuels with Ethanol for Alcohol" in accordance with the relevant provisions of the "Opinions on the Implementation of the Financial and Taxation Support Policies for Bioenergy and Biochemical Industries", and provided flexible subsidies to the state's key biofuel ethanol production enterprises. At present, the profit of these key enterprises mainly comes from state financial subsidies. Experts at the meeting proposed that lowering costs and reducing subsidies will be the focus of future industrial development. To this end, formulate consumption control standards for biofuel ethanol production processes, and technical standards for product quality, and harmonize fuel ethanol consumption quota standards, including material consumption and water consumption. Energy consumption is a powerful means of reducing costs and increasing efficiency.
Considering national food security, the National Development and Reform Commission recently made it clear that it will no longer approve fuel ethanol projects that use grain as raw materials, and new fuel ethanol projects must use non-food materials; according to the National Eleventh Five-Year Plan for renewable energy development, the The annual increase will be 2 million tons of non-grain raw material fuel ethanol. It is reported that Shanghai Jiaotong University, Henan Tianguan Company, etc. have made progress in the development of an antagonistic rod system for ethanol and butanol. Facing the advent of the "non-food second-generation biofuel era," it is also imperative to step up efforts to establish standards for non-food fuel ethanol.
With the support of the National Standards Committee, the National Standardization Technical Committee for Denatured Fuel Ethanol and Fuel Ethanol was recently established. Its secretariat is located in Henan Tianguan Company. Tianguan has established Tianzhiguan Renewable Energy Co., Ltd., which is fuel in Zhangjiang, Shanghai. Ethanol standardization research platform. According to the plan, within the next two to three years, the ethanol consumption standards for corn dry/wet process fuel, the ethanol consumption standard for wheat raw materials, the ethanol consumption standard for potato raw materials, and the ethanol consumption level for molasses raw materials will be formulated separately. Standards; at the same time carry out the revision of existing standards, including the modified fuel ethanol standard GB18350, the vehicle ethanol fuel standard GB18351; will also formulate the E85 ethanol gasoline standard and flexible fuel vehicle standard in the national standardization public welfare industry.
A leader of the Tianguan Group stated that the construction of the fuel ethanol standard system is a complex and arduous systematic project. It is hoped that the well-known universities, research institutes and enterprises in China will actively participate in the work of the Standardization Technical Committee, carry out close cooperation and jointly promote the development of the standard system.
Faced with the new situation of high food consumption, high cost, and high financial subsidies for food fuel ethanol, in response to the new requirements of the state to encourage the development of non-food fuel ethanol, and the new problems of unsatisfactory domestic promotion of ethanol gasoline, the 2008 China Biomass held recently At the Forum on the Construction of Energy Technology and Standards System, people in the industry pointed out that the infrastructure and standardization construction of the industry are backward and far from meeting the needs of development. They appealed that with the active participation of government departments, relevant research institutes and enterprises should cooperate. To jointly build a unified and efficient production, research and research platform, formulate fuel ethanol series standards as soon as possible, and promote the healthy and rapid development of the fuel ethanol industry.
