Solid state facilitated transport separation membranes using polymer electrolytes for alkene separation

摘要

The present invention relates to a solid state facilitated transport separation membrane prepared by using a polymer electrolyte, wherein the facilitated transport separation membrane has good stability and improved permeance and selectivity of alkene-series hydrocarbons. According to the present invention, the solid state facilitated transport separation membrane for the separation of alkene-series hydrocarbons is prepared by forming a polymer electrolyte layer consisting of a polymer and a metal salt to a porous membrane having good permeance and mechanical strength. The polymer electrolyte facilitated transport separation membrane thus prepared is characterized in that the permeance and selectivity to alkene hydrocarbons is high, and that the complex formed by a polymer ligand and a metal in the polymer electrolyte maintains its activity as a carrier of alkene even under dry operation.
