Synthesis and Characterization of ZSM-22 Zeolite

Liming Jia

Abstract

Through adding structure-directing agent,the zeolite ZSM-22 with good crystallinity was synthesized by hydrothermal crystallization method under dynamic condition.The results show that the structure-directing agent has obvious effect on synthesis process of the zeolite ZSM-22,can reduce crystallization time from 36h to 20h.At last,the ZSM-22 was characterized by XRD,TEM,TG-DTA techniques,effect of some parameters on synthesis process was investigated.
