Research progress in Cu/SiO2-based catalysts for dimethyl oxalate hydrogenation to ethylene glycol
摘要
Abstract
Coal-to-ethylene glycol(EG)route is a pivotal technology within the strategic framework of coal's clean and efficient utilization in China,and dimethyl oxalate(DMO)hydrogenation to EG is the key step in the route.Due to its outstanding catalytic performance and controllable cost,Cu/SiO2-based catalysts have achieved industrial application in DMO hydrogenation to EG.However,present technologies are still limited by high energy cost of H2 circulation and short catalyst lifespans.Firstly,the reaction pathway of DMO hydrogenation,the active sites of the catalyst and their structure-activity relationships,as well as the deactivation mechanism were introduced.Then,from the perspectives of structure-activity relationship and industrial application,the active center regulation strategies such as the composite preparation process,promoter modification and microscopic-mesoscopic structure design of the catalyst were analyzed.Finally,the future developments of Cu/SiO2-based catalysts for DMO hydrogenation to EG were prospected,such as studying the dynamic evolution and deactivation mechanism of surface species of catalysts,seeking more effective active center regulation indicators and developing Cu/SiO2-based catalysts suitable for low n(H2)/n(DMO)and their supporting processes.关键词
