Synthesis of ZSM-5 zeolite from expanded perlite and its catalytic performance in FCC gasoline aromatization

摘要

A hydrothermal synthesis method for ZSM-5 preparation was investigated by using expanded perlite as the only alumina source.The effect of crystallization conditions on ZSM-5 zeolite formation,such as temperature,time,pH,chemical composition of the reaction mixture,were studied The samples were characterized by XRD,IR,SEM,XRF and BET surface area measurements.The ZSM-5 zeolite from expanded perlite showed better catalytic activity for the FCC gasoline aromatization reaction compared to ZSM-5 prepared by the standard method
