Nanosized NaY zeolite was successfully synthesized by microwave heating at an ambient pressure and under reflux. The XRD and SEM results indicate that the resulted NaY zeolite has an average crystal size of 40 nm. The compact NaY zeolite membranes consisting of twinborn and polycrystalline crystal were synthesized on a porous alumina substrate by using pre-absorbed nanosized NaY zeolite obtained above and then by being combined with a secondary in situ synthesis. The measuring result for the separation of CO2/N-2 mixture show that the separating selectivity increased with increasing temperature, and reached a maximum of 4.0 at 1.40 degreesC.
