摘要

PURPOSE: A facilitated transport membrane is provided which displays excellent characteristics by coating a solid polymer electrolyte consisting of transition metal salts and polymers containing phthalic structure on a porous support. CONSTITUTION: The facilitated transport membrane is characterized in that it comprises porous support membrane and solid polymer electrolyte layer consisting of transition metal salts and polymers containing phthalic structure to separate alkene based hydrocarbon from hydrocarbon mixture, wherein cations of the transition metals have electronegativity of 1.8 to 2.3, wherein the transition metals are selected from the group consisting of Mn, Fe, Co, Ni, Cu, Mo, Tc, Ru, Rh, Pd, Ag, Re, Os, Ir, Pt and complex thereof, wherein lattice energy of the transition metal salts containing anions is 2500 kJ/mol or less, wherein the anions of the transition metal salts are selected from the group consisting of F¬-, Cl¬-, Br¬-, CN¬-, I¬-, NO3¬-, SCN¬-, ClO4¬-, CF3SO3¬-BF4¬-, AsF6¬-, PF6¬-, SbF6¬-, AlCl4¬-, N(SO2CF3)2¬- and C(SO2CF3)3¬-, wherein the transition metal salts comprise a mixture of complex salts or transition metal salts of transition metals, wherein the polymers are selected from polyethylene phthalate, poly diarylphthalate, poly(ethylene phthalate-co-1,4-phenylene phthalate) and a mixture thereof, wherein porous support is a porous polymer or ceramic support used in preparation of an ordinary composite membrane, and wherein the hydrocarbon mixture contains one or more of alkene based hydrocarbons and one or more of alkane based hydrocarbons or inert gases.
