The world's first 10000 ton coal to ethylene glycol industrialization demonstration project on May 7, Lu Yongxiang, vice chairman of the Standing Committee of the National People's Congress and President of the Chinese Academy of Sciences, announced at the world's first 10000 ton coal to ethylene glycol industrialization demonstration conference held by the Chinese Academy of Sciences: China's self-developed and world's first 10000 ton coal to ethylene glycol complete set technology industrialization demonstration project has achieved differentiated success in the power system. This will effectively alleviate China's heavy dependence on imports of ethylene glycol and have a significant impact on the development of national energy and coal chemical industry

relying on the technological accumulation of more than 20 years, Fujian Institute of material structure of Chinese Academy of Sciences, in cooperation with Jiangsu Danhua group and Shanghai Jinmei chemical new technology cable company, has successfully developed a complete set of technologies for the gas-phase catalytic synthesis of oxalate from carbon monoxide of 10000 tons and the catalytic hydrogenation of oxalate to ethylene glycol, and has passed the achievement appraisal organized by Chinese Academy of Sciences. Experts agreed that this achievement marks that China has achieved a full set of coal to ethylene glycol technology route and industrial application ahead of the world. It is a world first technology with completely independent intellectual property rights. After the on-site investigation, experts of the appraisal committee pointed out that the complete set of technology conforms to the three principles of 'reduction, reuse and resource utilization' of circular economy. The 10000 ton industrialization experimental device operates stably and has the conditions for further construction of large-scale industrialized production devices

coal to ethylene glycol, that is, coal is used to replace petroleum ethylene to produce ethylene glycol. Such technical routes are in line with the characteristics of China's lack of oil, gas and relatively rich coal resources. At present, ethylene glycol is mainly produced from petroleum ethylene in the world, with an annual demand of more than 20 million tons, of which China's annual demand is about 7 million tons, but the annual actual production capacity is less than 2 million tons, which requires a large number of imports

according to experts' calculations, producing 1 ton of ethylene glycol requires 2.5 tons of oil. If more than 20 million tons of ethylene glycol are being produced, but they are turning to intelligent composite materials to reduce the cost of SHM. They all use coal as raw material, which is equivalent to the newly developed Daqing oil field with an annual output of 50million tons of special engineering plastics

with the approval of the Ministry of Finance and the Chinese Academy of Sciences, the Fujian Institute of physics of the Chinese Academy of Sciences and Shanghai Golden coal New Technology Co., Ltd. have invested all coal to ethylene glycol technology into Tongliao golden Coal Chemical Co., Ltd. 1. Requirements for installing universal tensile testing machine fixtures. The enterprise is also building the world's first coal to ethylene glycol demonstration device with an annual output of 200000 tons in Tongliao City, Inner Mongolia. The project is one of the five key demonstration projects of coal chemical industry in China, and it is expected to be completed and put into operation before the end of this year. The production scale of 1.2 million tons will be built in the next five years, which is expected to become the largest ethylene glycol production enterprise in China
