Solid state polymer electrolyte facilitated transport membranes containing surfactants |
摘要 |
A facilitated transport membrane with improved permeance and selectivity to alkene-based unsaturated hydrocarbons is provided. The facilitated transport membrane includes a solid state polymer electrolyte and additionally a non-volatile surfactant that enhances long-term operation stability. In preparing the facilitated transport membrane for separation of alkenes, a porous supporting membrane is coated with a solid polymer electrolyte layer having a non-volatile polymer, a non-volatile surfactant, and a salt of a transition metal capable of complexing selectively and reversibly with alkenes.
