Mesoporous Si-MCM-48 membrane prepared by pore-filling method
Source abstract
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 5.66×10−7 mol/Pa·s·m2, and the H2/N2 separation factor was 3.47 under trans-membrane pressure of 0.05 MPa.
