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.
