Abstract: The present invention relates to a non-volatile facilitated transport separation membrane prepared by using a solid state polymer electrolyte, characterized in that it has good stability and improved permeance and selectivity of alkene-series unsaturated hydrocarbons. According to the present invention, the facilitated transport separation membrane for the separation of alkene-series hydrocarbons is prepared by forming a solid state polymer electrolyte layer consisting of a non-volatile polymer and a transition metal salt capable of selectively and reversibly forming a complex with alkenes to a porous membrane. The facilitated transport separation membrane thus prepared is characterized in that its permeance and selectivity of the alkenes are high, and that the complex formed by a polymer ligand and a metal in the solid state polymer electrolyte maintains its activity as a carrier of alkene-series hydrocarbons is maintained for a long time, even under dry, long-term operation.
