FACILITATED CO2 TRANSPORT MEMBRANE, METHOD FOR MANUFACTURING SAME, RESIN COMPOSITION TO BE USED IN METHOD FOR MANUFACTURING SAME, CO2 SEPARATION METHOD AND CO2 SEPARATION DEVICE

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.
