Abstract

A method for separating at least one gas in a gas mixture from at least one other gas in said gas mixture by selective permeation and providing a product that has been subjected to permeation containing at least one permeation gas, which comprises at least one in contact the gas mixture with a surface of a membrane, which membrane exhibits, with respect to at least a pair of gases of said gas mixture, a selective permeation of a gas of said gas pair over that of the remaining gas of said gas. Of gases, maintain the opposite surface of the membrane at a lower chemical potential for at least said permeation gas than the chemical potential on said surface, cause at least said permeation gas to pass through the membrane, and separate from the proximity of said opposite surface a product that has been subjected to permeation having a different proportion of said gas from said gas mixture with respect to said other gas of said mixture gaseous gas that ratio in said gas mixture of at least one gas relative to said other gas, characterized in that the membrane is a membrane of multiple components comprising a coating in occlusion contact with a porous separation membrane having a volume of holes important and comprising material, said material exhibiting a selective permeation of at least one gas of the gaseous mixture over that of one or more remaining gases of the gas mixture, wherein with respect to at least one pair of gases of said gas mixture, the material of the porous separation membrane exhibits a determined intrinsic separation factor of the coating material and the multi-component membrane exhibits a separation factor significantly greater than the determined intrinsic separation factor of the coating material and greater than the separation factor exhibited by the porous separation membrane.
