요약

To provide a CO2 membrane separation and recovery system that is excellent in CO2 permeability and CO2 separation selectivity on recovery of CO2 in a hydrogen production process and the like. The CO2 membrane separation and recovery system of the present invention comprises a dehydration treatment module (2) preliminary to a CO2 membrane separation module (1), the CO2 membrane separation module (1) comprises a hydrophilic zeolite membrane (3) that exhibits CO2 selective permeability and is formed on a porous substrate, and the hydrophilic zeolite membrane (3) is subjected to a dehydration treatment by a heat treatment at from 100 to 800°C.

대표청구항

A CO2 membrane separation and recovery system for a CO2 membrane separation and recovery from a gas mixture containing at least steam and CO2, the gas mixture being a natural gas or a biogas that contains methane gas as major component and steam, wherein the system comprises a dehydration means (2) preliminary to a CO2 membrane separation means (1), the CO2 membrane separation means comprising a hydrophilic zeolite membrane (3) that exhibits CO2 selective permeability and is formed on a porous substrate, the hydrophilic zeolite membrane (3) having been subjected to a dehydration treatment by a heat treatment at from 100 to 800°C.
