ABSORBENT MATERIAL OF CARBONIC ACID GAS AND METHOD FOR TREATING GAS CONTAINING CARBONIC ACID GAS

摘要

PROBLEM TO BE SOLVED: To provide a absorbent material of a carbonic acid gas showing high absorption performance of carbonic acid gas even after repeating absorption of carbonic acid gas and regeneration after a reduction in adsorption capability of a carbonic acid gas for a long period of time.

SOLUTION: The carbonic acid gas absorbent material comprises a porous particulate material having a through-hole and containing lithium silicate as a main component, wherein a wall thickness between an inner surface of the through-hole and an exterior surface is not larger than 3 mm in a cross section vertically crossing the through-hole.
