Title:
CO2 CAPTURE MATERIAL, AND CO2 SEPARATION DEVICE
Document Type and Number:
Japanese Patent JP2014113539
Kind Code:
A
Abstract:

To provide a CO2 separation-recovery device capable of separating-recovering CO2 by using a porous complex from CO2-including gas of including steam.

A CO2 separation-recovery method is provided for separating-recovering CO2 from CO2-including gas by using a CO2 capture material. The CO2 separation-recovery method includes: a step of capturing CO2 by making the CO2-including gas flow to a CO2 capture material container in which a CO2 capture material has a compound including an organic molecule and which is filled with the CO2 capture material; a step of desorbing and recovering the CO2 by heating the CO2 capture material; and a step of cooling the CO2 capture material, and has a step of reducing the steam concentration of the CO2-including gas before the step of capturing the CO2, in which the step of capturing the CO2 removes the CO2 by making the CO2-including gas flow to the CO2 capture material container after reducing the steam concentration.
