FACILITATED CO2 TRANSPORT MEMBRANE, METHOD FOR PRODUCING SAME, RESIN COMPOSITION FOR USE IN METHOD FOR PRODUCING SAME, CO2 SEPARATION MODULE AND METHOD AND APPARATUS FOR SEPARATING CO2

摘要

Provided is a facilitated CO2 transport membrane having improved CO2 permeance and improved CO2 selective permeability. The facilitated CO2 transport membrane includes a separation-functional membrane comprising a hydrophilic polymer gel membrane which contains a CO2 carrier and a CO2 hydration catalyst, wherein the hydrophilic polymer is a copolymer including a first structural unit derived from an acrylic acid cesium salt or an acrylic acid rubidium salt and a second structural unit derived from vinyl alcohol. More preferably, the CO2 hydration catalyst has catalytic activity at a temperature of 100° C. or higher.
