摘　　要：ZSM-5分子筛是应用广泛的催化体系,常用于烷烃的芳构化、催化裂化及异构化。近年来因其独特的孔道结构及表面酸碱特性,开始应用于低碳烷烃脱氢。本文综述了Zn/ZSM-5及Ga/ZSM-5催化剂对低碳烷烃的脱氢理论研究,概述了Fe/ZSM-5、Cr/ZSM-5、Pt/ZSM-5以及一些其他过渡金属催化剂对低碳烷烃的催化应用;探讨了ZSM-5基催化剂的影响因素如硅铝比、焙烧温度及制备方法等,以利于对低碳烷烃脱氢作进一步了解;最后对ZSM-5催化体系进行了评述及展望。ZSM-5 molecular sieve is widely used as catalyst for aromatization, catalytic cracking and isomerization. Recently the ZSM-5 is applied to light alkane dehydrogenation due to its unique bore configuration and the character of surface acidity. This paper summarizes the progress of ZSM-5 in application and theoretical research for light alkane dehydrogenation, including Zn/ZSM-5, Ga/ZSM-5 for dehydrogenation theory, and the ZSM-5 catalysts modified with Fe, Cr, Pt and some other transition metals prepared by liquid-ion exchange and impregnation methods. The influencing factors of ZSM-5 based catalysts such as Si/Al, calcination temperature and the preparation methods are discussed. Future prospects of the ZSM-5 based catalysts are provided.
