摘　　要：为解决目前催化剂存在的易烧结、稳定性差等缺点,自主研发了新型催化剂。通过20万t/a乙二醇装置侧线试验对比表明,与市场主流催化剂相比,自主研发的新型催化剂反应温度较低,长期运行压降小,整体指标均优于市面主流催化剂。In order to solve the problems of easy sintering and poor stability of existing catalyst,a new type of catalyst is developed independently. Through evaluating on a 200 000 ton/year ethylene glycol unit,the new catalyst exhibits lower reaction temperature,lower pressure drop in long-term operation,and better overall indexes than mainstream catalysts in the market.
