Glycol catalyst prepared by dimethyl oxalate hydrogenation and preparation method thereof

The invention discloses a glycol catalyst prepared by dimethyl oxalate hydrogenation and a preparation method thereof, which is characterized in that the catalyst takes copper nitrate or copper acetate as copper source, ludox as silicon source, ammonia, ammonium bicarbonate or urea as precipitant which are coprecipitated to prepare CuSi catalyst forerunner; one or two of Zn, Fe, Ag, and Pd is soaked in the catalyst forerunner and used as additive agent, and then mixture is baked in the temperature of 200 to 500 DEG C, and finally is beaten into pieces and formed to obtain the catalyst. The catalyst comprises 20-50% of Cuo, 0.005%-3% of additive agent and the rest of SiO2 according to mass percent of oxygen compound, wherein additive agent is oxidate of one or two of Zn, Fe, Ag, and Pd. Before using, the catalyst is reduced by hydrogen and nitrogen combination gas containing 1% to 90% of hydrogen; and the reduction temperature is 150 to 500 DEG C.
