Abstract
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 SrCaFeO, 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.
