摘要:
A gas separation membrane system and a method of preparing such gas separation membrane system by providing a porous support upon which is supported a membrane layer comprising a first gas-selective material and having a membrane thickness and removing therefrom a substantial portion of the first gas-selective material from the membrane layer by the use of an ultra-fine abrasive to thereby provide the membrane layer having a reduced membrane thickness. A second gas-selective material is deposited upon the membrane layer having the reduced membrane thickness to provide an overlayer of the second gas-selective material having an overlayer thickness so as to thereby provide the gas separation membrane system having the membrane layer of the reduced membrane thickness and the overlayer of the overlayer thickness.
摘要:
A gas separation membrane and a method of manufacturing such gas separation membrane that comprises a porous substrate treated with a layer of metal-coated inorganic oxide particles and with the layer of such metal-coated inorganic oxide particles being coated with an overlayer of a gas-selective material.
