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。

Abstract

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.
