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/SiO

-based catalysts have achieved industrial application in DMO hydrogenation to EG. However

present technologies are still limited by high energy cost of H

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/SiO

-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/SiO

-based catalysts suitable for low

(DMO) and their supporting processes.
