Primary Hydrothermal Synthesis and Technological Conditions Optimization of ZSM-5 Membrane

ZSM-5 zeolite membranes are successfully synthesized by in-situ hydrothermal synthesis on the self-made ceramic support with the TPAOH as the templating agent primary.Many key factors during the growing process of zeolite membrane are discussed,such as,the dosage of alkali(pH),crystallizing time and the dosage of the template.The best molar composition and crystallizing time for synthesis are optimized.Crystal phase of the power and morphology of the membranes are characterized by XRD and SEM.ZSM-5 zeolite membranes are roasted at different temperatures and then permeated with N_2.
