【Abstract】 Results of simulation text for catalytic hydrogenation of diethyl oxalate to ethylene glycol are reported in this article. Under 0. 6-3. 0 MPa and at 200-240 C, a diethyl oxalate conversion of over 99% and selectivity of 95. 3% to ethylene glycol was achieved on Ec-13 catalyst. No decrease in catalytic activity and selectivity was observed in 1134 hours of hydrogenation reaction.更多还原
