| 摘 要： | 歧化与烷基转移反应是芳烃生产的重要环节。综述了歧化与烷基转移反应目前主要应用的丝光(MOR)沸石、β沸石、ZSM-5沸石催化剂。MOR和β沸石主要用于甲苯歧化和C9的烷基转移反应,ZSM-5沸石主要用于甲苯的择形歧化反应。沸石催化剂适用的原料及反应由其结构、酸性等因素决定。优化分子筛的结构和酸性是歧化与烷基转移反应催化剂发展的方向。

| Abstract: | Disproportionation and transalkylation reactions are key links in aromatics production. Mor denite （MOR） , β- zeolite, ZSM 5 catalysts used for the above mentioned reactions currently were reviewed with 24 references. MOR and β - zeolite were used mainly for toluene disproportionation and C9 transalkylation, and ZSM 5 was used for shape selective toluene disproportionation. To what materials and reactions did the zeolite catalysts adapted depended on the catalyst＇s structure and acidity. It was pointed out that optimizing the zeolite＇s struc tures and acidity was the development direction of disproportionation and transalkylation catalysts. |
