<p>PROBLEM TO BE SOLVED: To efficiently remove CO2 generated from an equipment of such as a thermal power station, by preparing a CO2 absorption material from elements selected from the group of Ba, Sr, Ca, elements from the group of La, Pr, Ce, and elements from Ti, Mn, Fe. SOLUTION: As a material to absorb and remove CO2 selectively and directly from a high temperature exhaust gas, the CO2 absorbing material is prepared by using at least one kind of element selected from the group of Ba, Sr, Ca, Cs, K, one element selected from the group of La, Pr, Ce, Nd, Gd, Y, Pb, Bi, and at least one kind of element selected from the group of Ti, Mn, Fe, Co, Ni, Cu, Al, Sn, Zr. The CO2 absorbing material is prepared so as to have a perovskite complex oxide structure represented by a formula ABO3 (where A is a kind of element selected from Ba, Sr, Ca; B is a kind of element selected from Ti, Mn, Fe).</p> |
