| titleOfInvention | Catalyst for synthesizing ethylene glycol by dimethyl oxalate gas phase hydrogenation and preparation method thereof |
| abstract | The invention relates to a catalyst for synthesizing ethylene glycol by dimethyl oxalate gas phase hydrogenation and a preparation method thereof, and mainly solves the problems of low ethylene glycol selectivity and low yield in the prior art. The technical scheme is that a unique Cu/modified SiO for synthesizing the ethylene glycol by gas-phase hydrogenation of dimethyl oxalate through doping of transition metal Zr/Ti/Ce, modifying a silicon dioxide-containing compound at high temperature, adjusting the internal pore structure of a silicon dioxide carrier and combining an ammonia evaporation method 2 A catalyst. Cu/modified SiO of the invention 2 The catalyst is applied to the reaction of synthesizing the glycol by gas-phase hydrogenation of the dimethyl oxalate, and shows extremely high hydrogenation activity and glycol selectivity. |
