Abstract

Mesoporous MCM-48 membranes were prepared on asymmetric zirconia tubular support with an average pore size of 0.2 μm by hydrothermal method. The support should be pretreated with H₂O as a pore-filling substance to prevent the sol solution from infiltrating into the support pores. The SEM showed that the MCM-48 membrane was composed of tightly-connected spherical crystal. The single gas N₂ and H₂ permeation experiments confirm that crack-free membrane could be prepared by pore-filling method. N₂ permeance of MCM-48 membrane, synthesized by secondary growth, can reach 5.66x10^-7 mol/Pa-s-m², and the H₂/N ₂separation factor was 3.47 under trans-membrane pressure of 0.05 MPa.
