Abstract
Multicomponent membranes for gas separation are disclosed which are effective for separating at least one gas from gaseous mixtures by permeation wherein the multicomponent membranes are comprised of a coating in occluding contact with a porous separation membrane. The multicomponent membranes advantageously exhibit less resistance to permeate gas flow for the at least one gas than for at least one remaining gas in the gaseous mixture. For at least one pair of gases the separation factor of the multicomponent membrane is significantly greater than the determined intrinsic separation factor of the material of the coating. Processes and apparatus for gas separation utilizing the multicomponent membranes are also disclosed.
