Solid state polymer electrolyte facilitated transport membranes containing surfactants

Abstract

Disclosed is a novel facilitated olefin transport membrane with improved permeance and selectivity to alkene-based unsaturated hydrocarbons, which includes a solid state polymer electrolyte and additionally a non-volatile surfactant that remarkably enhances the long-term operation stability. In the preparation of the facilitated transport membrane for separation of alkenes, a porous supporting membrane is coated with a solid polymer electrolyte layer comprising a non-volatile polymer, a non-volatile surfactant and a salt of a transition metal capable of completing selectivity and reversibly with alkenes.
