摘要：
Preparation and improvement of the ZSM-5 membrane selectivity by the sol-gel method as a post-synthetic treatment was reported. The carbon dioxide adsorption amount in the membrane was found to increase with increasing pressure and back diffusion reduced with increasing transmembrane pressure. With the increase in amount of carbon dioxide in feed gas the separation factor also increased.
