摘　　要：介绍了非石油路线合成的乙二醇粗产品提纯工艺的研究进展,主要针对煤路线和生物质路线,对各种工艺技术特点进行了评述。非石油路线具有较好的发展前景,针对其粗产品中难以分离的1,2-丙二醇(1,2-PG)和1,2-丁二醇(1,2-BD),探讨了不同方案的分离效果,并对低能耗的分离工艺应用前景进行了展望。Summarized the separation process research of crude product from the coal and biomass catalyt- ic conversion routes, the technical characteristics of the various processes were reviewed. As the non-oil route has good prospects for development, unlike oil route, the crude product contains closed boiling point impurities propylene glycol and 1,2-butanediol which are hard to separate from ethylene glycol. It also discusses the separation effect of different schemes, and the low energy separation technology application prospect.
