Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 酸素供給側ガスあるいは酸素受入れ側ガスを 特別なガス圧状態とする必要がなく、比較的広い温度域 において酸素の分離除去、富化等の酸素含有ガスの処理 が可能な酸素含有ガス処理方法を得、さらにこの方法に 使用される酸素含有ガス処理材料を得る。 【構成】 一般式ABO X (AはSr,La,Ba,P b,Caから選ばれた1つ、BはCo,Fe,Zrから 選ばれた1つ、x=1〜3)で表されるペロブスカイト 型化合物に対してA及びB以外の金属をドープしたドー プ処理済ペロブスカイト型化合物(p)を酸素含有ガス 処理材料とし、これを0〜900℃の範囲で酸素を含有 する処理対象ガスと接触させることによって、ドープ処 理済ペロブスカイト型化合物(p)に酸素を収着させ て、前記処理対象ガスより酸素を除去し、さらにこの化 合物より酸素を脱離させて酸素富化をおこなう。 (57) [Summary] [Purpose] Oxygen-containing gas such as oxygen separation and enrichment in a relatively wide temperature range without the need for a special gas pressure condition for the oxygen supply side gas or the oxygen reception side gas. To obtain an oxygen-containing gas treatment method, and further obtain an oxygen-containing gas treatment material used in this method. [Structure] General formula ABO x (A is Sr, La, Ba, P One selected from b and Ca, B is one selected from Co, Fe and Zr, and a perovskite-type compound represented by x = 1 to 3) is doped with a metal other than A and B. The treated perovskite-type compound (p) is used as an oxygen-containing gas treatment material, and the treated perovskite-type compound (p) is exposed to oxygen in the range of 0 to 900 ° C. to give oxygen to the doped perovskite-type compound (p). Sorption is performed to remove oxygen from the gas to be treated, and oxygen is desorbed from this compound to enrich oxygen.
