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.
