SEPARATION OF H2/CO BY THE SELECTIVE SORPTION PROPERTY OF H3PMo12O40 EMBEDDED IN POLYVINYLALCOHOL MEMBRANE
H2 and CO permeabilities through H3PMo12O40-blended polyvinylalcohol membrane and catalyst-free polyvinylalcohol membrane were measured. The blended membrane showed better selectivity and higher permeation flux of H2 than the catalyst-free polyvinylalcohol membrane. Its enhanced H2 separation ability was mainly due to the selective sorption property of PMo embedded in the polyvinylalcohol membrane.
