Abstract
Provided is a facilitated CO2 transport membrane having an improved CO2 permeance and an improved CO2/H2 selectivity. The facilitated CO2 transport membrane includes a separation-functional membrane that includes a hydrophilic polymer gel membrane containing a CO2 carrier and a CO2 hydration catalyst. Further preferably, the CO2 hydration catalyst at least has catalytic activity at a temperature of 100° C. or higher, has a melting point of 200° C. or higher, or is soluble in water.
