  • Oxygen adsorbent, oxygen manufacturing equipment using the oxygen adsorbent and oxygen manufacturing method
    Patent number: 10105678
    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 Sr1?xCaxFeO3??, wherein 0.12?x?0.40, 0???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.
    Type: Grant
