现代煤化工产业的精细化发展

Current situation and prospects regarding development of modern coal chemical industry and its fine chemical production

随着中国煤化工工艺技术和示范工程建设不断取得重大进展,煤化工产业开始从传统煤化工向现代煤化工转型升级。"十二五"以来,中国现代煤化工在新技术开发、核心装备突破、产业规划和布局、示范工程建设和运行等方面都取得了重要进展,为实施能源替代和保障国家能源安全做出了积极贡献。精细化是煤化工产业未来的发展趋势,它既能解决传统煤化工产品雷同、竞争力差,产能过剩等问题,又能改善煤化工产业能源转换效率和资源综合利用水平偏低的现状。本文综述近年来中国在煤制烯烃、煤制油、煤制乙二醇、煤制天然气等重点领域的技术进展,提出了未来加强精细化、高端化发展方向的建议。

With a great progress of China＇s coal chemical technology and demonstration projects, coal chemical industry is stepping in an upgrading way instead of the traditional way. During the period of ＂12th Five Year Plan＂, China has made great achievements in the development of new technology, new breakthroughs in core equipment, industrial planning and layout, demonstration project construction and operation of modern coal chemical industry, which contribute to the implementation of altenlative feedstock and the protection of national energy security. In this process, fine chemical production of modern coal chemical downstream chain is to be the trend to solve the problems like similar products, less competitiveness, overcapacity brought by traditional ways. It can also improve the coal chemical industry energy conversion efficiency and resource comprehensive utilization. In this paper, we introduced and discussed the progress about coal to oil, coal to ethylene glycol, coal to natural gas and other key areas of technology in recent years. Also, we give some suggestions and thoughts about the development direction of high-end fine chemical in future.
