Study on the Catalysts for Hydrogenation of Dimethyl Oxalate to Ethylene Glycol

Amorphous alloy catalysts of Cu-B/γ-Al2O3 and Cu-B/SiO2 were prepared by means of chemical reduce deposition method and characterized by XRD and TDA in order to improve the catalytic performance and selectivity of the catalyst used for the hydrogenation of dimethyl oxalate to ethylene glycol developed by the usual method.The catalysts were evaluated under the following condition:2.0 MPa,n(H2)∶n(DMO)=50∶1,200℃ and LHSV=2h-1.The catalytic performance and selectivity of the amorphous alloy catalysts of Cu-B/γ-Al2O3 and Cu-B/SiO2 is better,and they have good application prospect.
