OXYGEN-SELECTIVE ADSORBENT HAVING FAST ADSORPTION RATE AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a method for preparing an oxygen-selective adsorbent for selectively adsorbing oxygen in the air. The invention provides a method for preparing an oxygen-selective adsorbent which comprises a step of preparing BaMg(CO 3 ) 2 particles or particles in which MgCO 3 orMg(OH) 2 are attached to the outside of BaMg(CO 3 ) 2 and a step of burning the particles at a high temperature, and the oxygen-selective adsorbent prepared thereby. The oxygen-selective adsorbent according to the invention adsorbs oxygen in the air at a fast rate compared with an existing oxygen-selective adsorbent. In addition, high thermal stability and excellent oxygen adsorptivity are ensured.
