ZEOLITE MEMBRANE SEPARATION AND RECOVERY SYSTEM FOR CO2 |
摘要 |
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. |
