CARBON DIOXIDE ABSORBING MATERIAL, AND METHOD AND APPARATUS FOR SEPARATING CARBON DIOXIDE USING THE SAME

摘要

A carbon dioxide absorbing material which comprises, as a main component, a composite oxide containing a component substance X, which is at least one of Sr and Ba, and Ti in a mole ratio (X/Ti) of 1.8 to 2.2; the carbon dioxide absorbing material wherein the material is produced by firing a substance having a perovskite structure and containing X and Ti in a mole ratio (X/Ti) of 0.9 to 1.1, or at least one of a green sheet, a waste material from a green sheet, a waste material from a green sheet laminate and a green sheet precursor comprising the substance, in the presence of at least one of strontium carbonate and barium carbonate; and an apparatus for separating carbon dioxide, which comprises a carbon dioxide absorbing mechanism section (A) wherein carbon dioxide is absorbed by the use of the above carbon dioxide absorbing material (3) under a pressure of 1.0 X 10
