There is provided a facilitated transport membrane for separating alkene hydrocarbon comprising a solid polymer electrolyte layer consisting a transition metal salt, a polymer, an ionic liquid, and a porous supported membrane. The facilitated transport membrane of the present invention shows high selectivity and permeability for the alkene hydrocarbon. It further maintains the complex's activity as a carrier during a long operation, wherein the complex is formed by an interaction of the transition metal ion with the polymer ligand within the solid polymer electrolyte. |
