Preparation of self-supported crystalline merlinoite-type zeolite W membranes through vacuum filtration and crystallization for CO2/CH4 separations

摘要

Zeolite W membranes were grown on their seed pellets prepared via a straightforward vacuum filtration method followed by crystallization, rendering them self-supported. Herein, the feasible application of self-supported zeolite W membranes for CO2/CH4 separation with astonishing CO2/CH4 selectivity was demonstrated.
