简单介绍了草酸二甲酯加氢制乙二醇是“煤制乙二醇“技术路线中的一个关键步骤,通过调控催化剂活性,草酸二甲酯经选择性加氢还可得到乙醇酸甲酯和乙醇;概述了国内外草酸二甲酯选择性加氢分别制乙醇酸甲酯、乙二醇和乙醇反应催化剂的最新研究进展;重点探讨了通过改变催化剂组成、促进剂以及反应条件,进而实现草酸二甲酯加氢反应活性和产物选择性调控的研究结果;指出了草酸二甲酯选择性加氢催化剂研发过程中存在的问题和挑战以及未来的发展趋势。

It is introduced that the hydrogenation of dimethyl oxalate(DMO) to ethylene glycolate(EG) is a key step for "syngas to EG" process.Methyl glycolate(MG) or ethanol can also be produced via the selective hydrogenation of DMO over well-designed catalysts with proper activity.The latest progresses in the catalyst research for the hydrogenations of DMO to MG,EG and ethanol are reviewed.The achievements in controlling the reaction activity and product selectivity in the hydrogenation of DMO by adjusting the catalyst composition,additives and the reaction conditions are investigated.In addition,questions in the present research and trends in the future research for the catalysts of the selective hydrogenation are discussed.
