CO2-facilitated transport membrane, production method thereof, resin composition used in the production method, CO2 separation module, CO2 separation method and apparatus

摘要

Provided is a facilitated CO 2 transport membrane having improved CO 2 permeance and improved CO 2 selective permeability. The facilitated CO 2 transport membrane includes a separation-functional membrane comprising a hydrophilic polymer gel membrane which contains a CO 2 carrier and a CO 2 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 CO 2 hydration catalyst has catalytic activity at a temperature of 100°C or higher.
