Preparation, Hydrogen Separation and Hydrothermal Stability of Microporous Silica Membrane
Source abstract
Abstract
Microporous silica membranes on Υ-Al2O3/α-Al2O3 porous supports were prepared by a sol-gel process, and characterized by IR, TG, FE-SEM,N2 adsorption as well as gas permeation. The H2 permeance of 2.3×10-7mol·m-2·Pa-1·s-1 and H2/CO2 separation factor of 8.0 were measured with the as-prepared membrane at 200℃. Deterioration of the membrane performance in the humid atmoshphere was observed, which can be attributed to the collapse of the pore structure caused by the reaction between surface hydroxy group and water vapor.
