摘要
作为合成气制乙二醇关键步骤之一,CO与亚硝酸甲酯合成草酸二甲酯备受关注。综述了近年来CO气相偶联合成草酸二甲酯Pd/α-Al_2O_3催化剂失活与再利用研究进展,探讨催化剂再利用工艺存在的问题,指出应根据在工业应用中出现的问题对Pd/α-Al_2O_3催化剂进行失活研究,在此基础上开发针对性的再生工艺;钯催化剂回收方面萃取法和吸附法逐渐成为研究重点,高效、低耗、短流程绿色工艺的开发是失活钯催化剂再利用的发展方向。
As one of the key steps in syngas to ethylene glycol,synthesis of dimethyloxalate(DMO)from CO and methyl nitrite has attracted much attention.Recent progress in deactivation and reuse of Pd/α-Al2O3 catalyst for DMO synthesis was reviewed.Problems existing in the reutilization process of Pd/α-Al2O3 catalyst were analyzed,and future development direction was discussed.It was pointed out that research on deactivation of Pd/α-Al2O3 catalyst should based on problems in industrial application to develop target regeneration process.Extraction and adsorption process of Pd/α-Al2O3 catalyst recovery gradually became focus of this area.Development of high efficiency,low cost and green process was reutilization direction of deactivated Pd/α-Al2O3 catalyst.
