The Phase Transformation in the Crystallization Process of Fe-Mordenite Zeolite

Abstract

In the present paper, we reported the influence of the crystallization time on the crystallinity of the Fe-mordenite zeolite (Fe- MOR). The obtained results showed that, in order to reach the high crystallinity of zeolite the optimal duration of crystallization was about 36 h. When crystallization time increased from 48h to 72h, there was phase transformation from MOR zeolite to ZSM- 5 zeolite. However, if crystallization time decreased (< 24 h) the obtained samples had low crystallinity.
