Abstract:

The present status and development trends of ethylene glycol（EG）production technology are summarized. The oil ethylene route is currently the main process for producing EG in chemical industry. While，the technology of EG from coal meets the energy character of China with high economic efficiency，which would take the advantage of coal resource that is relatively rich in China. After nearly 30 years of research，with the cooperation of enterprises，Fujian Institute of Research on the Structure of Matter，CAS，have completed the first industrialization set of EG from coal in the world.

摘要：

综述了目前乙二醇生产工艺技术的现状和发展动向，指出了石油乙烯路线是目前乙二醇工业生产的主要工艺。同时，着重介绍了中国科学院福建物质结构研究所与企业合作，率先在国内外实现工业化的煤制乙二醇的成套技术。该技术符合我国缺油、少气、煤炭资源相对丰富的资源特点，可利用煤炭资源生产乙二醇，代替目前的石油乙烯路线，将有效缓解我国乙二醇产品供需矛盾，逐步实现我国以煤代油生产乙二醇的战略目标，节省大量石油资源，对国家的能源和化工产业产生重要积极影响，代表了当今煤化工领域的前沿发展方向之一。
