Popis: We have identified a class of facilitated-transport membranes for the production of oxygen-enriched air. The membranes consist of a transition-metal complex dissolved in a suitable solvent and immobilized within the pores of a microporous membrane. Under certain conditions, these membranes exhibited oxygen/nitrogen selectivities in excess of 20, and permeate streams with oxygen purity in the range of 80–90 mole% were achieved using a l-atm feed stream and a low-pressure permeate stream. An oxygen permeability (Po2 = 26 x 10−9 cm3 (STP)-cm/cm2-sec-cmHg) about one-half that of silicone rubber was observed. Membrane life is measured in weeks.
