Catalyst for hydrogenation of oxalic ester to ethanol, method of preparing the catalyst, and method of using the same |
摘要 |
A catalyst including: a support, the support including a mixture of SiO2 and ZrO2; an active ingredient including copper; a first additive including a metal, an oxide thereof, or a combination thereof; and a second additive including Li, Na, K, or a combination thereof. The metal is Mg, Ca, Ba, Mn, Fe, Co, Zn, Mo, La, or Ce. Based on the total weight of the catalyst, the weight percentages of the different components are as follows: SiO2=50-90 wt. %; ZrO2=0.1-10 wt. %; copper=10-50 wt. %; the first additive=0.1-10 wt. %; and the second additive=0.1-5 wt. %. |
