reporter learned from East China University of science and technology on April 6 that the technical achievements of coal to ethylene glycol developed by Professor Li Wei of the University have "come to fruition" in Inner Mongolia Yili resources group and Anhui Huaihua group. The two large-scale units officially put into operation can produce 300000 tons and 100000 tons of high-grade ethylene glycol each year.


according to experts, the catalyst index of this technology is advanced, and the scale of a single set reaches 100000 tons / year, which is a leap forward in China's coal to ethylene glycol industrial technology.


ethylene glycol are the main raw materials often used in polyester fiber and mineral water bottle in daily life. They are mainly processed by petroleum for a long time, but the self-sufficiency rate of China has been less than 30%. However, the production of ethylene glycol from coal-based syngas can partly replace petroleum. "China is a country with poor coal and little oil. The production of ethylene glycol from coal-based syngas is of strategic significance to the national economic development, and compared with the petrochemical route, the economic benefits are also better." Li Wei told China Science Daily. It is reported that in 1998, the United Institute of chemical reaction engineering of East China University of science and technology started the research on the technology of producing ethylene glycol from coal-based syngas. In 2009, the University reached a cooperation agreement with Shanghai Pujing Chemical Technology Co., Ltd. and Anhui Huaihua group to build a 1000 t / a pilot plant of coal-based syngas to ethylene glycol in Anhui Huaihua group. In August 2011, the pilot plant successfully produced high-grade ethylene glycol products, which verified the rationality of the technology and obtained further enlarged data, which laid a solid foundation for the industrialization of the technology. Up to now, Huali has authorized 6 customers for its technological achievements, reaching a scale of 1.6 million tons / year for 7 sets of units, and each unit is in the process of industrialization.
