Gas Seperation By Membrane

A multilayer composite ceramic membrane was prepared by depositing a nano scale layer of SiO2 on top of a modified porous alumina supported by chemical vapor deposition (CVD) method. The modification of the support was carried out by adding a graded layer of Al2O3 (ɣ-alumina phase) , using sol gel method.With doing different expriments ,the amount of selectivity increased,although the permeation flux reduced
