Adsorbable gases can be separated by porous ceramic membranes under the capillary condensation mechanism of membrane separation

on which prior study was only limited to pure components. Based on researches of vapor permeation separation of ethanol - water mixtures via modified alumina membranes

this paper optimizes the model equations of capillary condensation mechanism for membrane separation of binary gas mixtures which can calculate the permeability of binary gas mixtures accurately and established the transfer model in porous ceramic membranes which is proved reliable by simulating vapor permeation separation.
