摘要
Abstract
The Cu/SiO2 catalyst prepared by coprecipitation method with urea as precipitator were treated by hydrothermal aging. Effects of hydrothermal treatment temperature and time on the performance of the catalysts for hydrogenation of dimethyl oxalate (DMO) to ethylene glycol (EG) were investigated. The results showed that the catalyst treated at 120℃ for 36h exhibited optimal catalytic activity and selectivity, obtaining a DMO conversion of 100% and a EG selectivity of 96.2% under the reaction conditions of 473K, 2MPa, H2/DMO mole ratio of 80 and LHSV of 1.0 h-1. BET and SEM characterization results indicated that both of hydrothermal temperature and time affected the structure and reducibility of the Cu/SiO2 catalysts, thereby affecting their catalytic performances.关键词
