ACCELERATED TRANSPORT SEPARATION MEMBRANE INCLUDING SOLID POLYMERIC ELECTROLYTE LAYER CONSTITUTED OF TRANSITION METAL SALT AND POLYMER HAVING CARBON DOUBLE BOND AND POROUS SUPPORT FILM

摘要

PROBLEM TO BE SOLVED: To provide an accelerated transport separation membrane used for separating an alkene hydrocarbon from a hydrocarbon mixture, including a solid polymeric electrolyte layer constituted of a transition metal salt and a polymer having a carbon double bond and a porous support film.

SOLUTION: The accelerated transport separation membrane is produced by forming a solid electrolyte on the porous support film. Herein, the solid electrolyte is constituted of the transition metal salt and the polymer having the carbon double bond to selectively and reversibly form the alkene hydrocarbon and a complex.. Especially, since a polymer matrix contains the carbon double bond capable of forming the complex with transition metal ions, it well liberates the transition metal salt. The accelerated transport membrane thus produced is characterized in that the permeation and selectivity to the alkene hydrocarbon is high and the complex of a metal and a polymeric ligand in the solid polymeric electrolyte keeps activity as a transport element of the alkene hydrocarbon even under a long-term drying operation condition.
