Synthesis of and Characterization of ZSM-22 zeolite

Yiliang Chen

Abstract

The ZSM-22 zeolite has been synthesized by means of the hydrothermal synthesis method using 1,6-diaminohexane as a template.The effect of synthesis conditions on ZSM-22 zeolite was studied.The synthesized sample were characterized by XRD and SEM.The synthesised ZSM-22 zeolite was highly crystalline and free of amorphous material under the following optimal dynamic synthesis conditions: temperature 433 K、90(SiO2)∶1(Al2O3)∶27(DAH)∶27(K2O)∶3 600(H2O),tetraethyl orthosilioate as the silica source.
