OXYGEN ADSORBENT, OXYGEN MANUFACTURING EQUIPMENT USING THE OXYGEN ADSORBENT AND OXYGEN MANUFACTURING METHOD

摘要

An oxygen adsorbent which can be manufactured at a low cost, and an oxygen manufacturing equipment and an oxygen manufacturing method which are capable of producing oxygen-enriched gas at a low cost by using the oxygen adsorbent are provided. The oxygen adsorbent comprises at least an oxide of a perovskite structure. The oxide is represented by a compositional formula of Sr1−xCaxFeO3−σ, wherein 0.12≦x≦0.40, 0≦σ≦0.5 Since this oxide does not include La and Co included in a conventional oxygen adsorbent, it can be manufactured at a low cost.
