摘要/Abstract

摘要： 草酸二甲酯催化加氢生产乙二醇是煤化工产业的重要组成部分。目前以Cu/SiO₂为催化剂的研究工作得到广泛关注，但铜催化剂的失活问题是目前面临的最关键问题，阻碍了其进一步工业规模的发展。本文综述了最近国内外对于草酸二甲酯加氢反应中铜催化剂稳定性的研究进展，分析了铜催化剂的失活机理，讨论提高铜催化剂稳定性的合理有效的方法。文章指出从增强铜-其他物种相互作用而限制铜物种移动、提高载体的传热能力以消除反应过程中的局部过热点、制备特殊结构载体隔离铜颗粒以阻止其迁移团聚等方面，积极探索新的催化剂合成方法和新材料的制备，解决铜催化剂的失活问题，对于合成气经草酸二甲酯加氢制备乙二醇及乙醇酸甲酯等化工产品具有重要的学术价值和实用意义。

Abstract: The hydrogenation of dimethyl oxalate(DMO) to ethylene glycol(EG) is an important component of the coal chemical industry. Cu-SiO₂ catalysts for the hydrogenation of DMO have attracted great attention, but the poor stability and short lifespan of the copper catalysts severely restrict their large-scale industrial applications. This review mainly focused on the latest progress on the stability of the Cu-based catalysts for the hydrogenation of DMO. Deactivation mechanisms and some reasonable methods to improve the stability of the copper catalysts were discussed in detail. It is of great academic and industrial significance to pursue new methods for the preparation of efficient and long lifespan catalysts for the hydrogenation of DMO to EG and methyl glycolate(MG) through enhancing the interaction between the copper species and the support or the second metal, improving the heat transfer efficency of the carrier and using the supports with special structure to isolate copper particles, etc.
