| titleOfInvention | Catalyst composition, synthesis method and application |
| abstract | The invention relates to a catalyst composition, a synthesis method and application, and mainly solves the technical problems of low activity and selectivity and poor stability in the prior art. The catalyst composition has a chemical formula of M-Cu-X/SiO 2 ‑ZrO 2 (ii) a Wherein M is at least one selected from the group consisting of oxides of Mg, Ca, Sr, and Ba; x is at least one selected from the group consisting of oxides of Ti, V, Cr, Zn, Fe, Ni, Co and Mn; the weight portion of M is 2-12 portions, Cu element is 10-40 portions, X is 2-20 portions, SiO 2 ‑ZrO 2 The content of (A) is 28-86 parts; SiO 2 2 ‑ZrO 2 Medium, ZrO 2 Is SiO 2 ‑ZrO 2 The weight ratio of (A) is 1-20%. The catalyst can be used in the industrial production of ethylene glycol by hydrogenation of oxalate. |
