| 摘要 |
The present invention relates to an oxygen adsorbent composition for removing or producing oxygen containing perovskite-type powder represented by La_(1-x)Sr_xCo_(1-y)Fe_yO_(3-δ) (wherein x is in a range of 0 <= x <= 1, y is in a range of 0 <= y <= 1, and δ is in a range of 0 <= δ < 2). In addition, the oxygen adsorbent has excellent oxygen adsorption characteristics under x, y, and a specific temperature condition. The oxygen adsorbent composition of the present invention can be usefully used in an adsorption process for separating oxygen in high-temperature regions at more than or equal to 500 °C, and can be used in a pure oxygen combustion process or the like in order to provide high-purity oxygen. |
