摘　　要：介绍了EUO、SM - 3和MgAPSO - 31等分子筛应用于二甲苯异构化催化剂的研究成果 ;总结和讨论了改性丝光沸石和ZSM - 5分子筛对二甲苯异构化催化剂反应性能的影响 ;并对二甲苯异构化催化剂的发展前景进行了展望 。In this paper, the latest advance in the research on xylene isomerization catalyst is reviewed. The research results of using new types of zeolite,such as EUO, SM-3 and MgAPSO-31 are especially introduced.The effects of modified ZSM-5 and mordenite on the reaction performance of xylene isomerization catalyst are discussed.In the future,the research on xylene isomerization catalyst should be focused on improving its activity and stability as well as selectivity.
