The present invention relates to new zeolitic adsorbent materials which are particularly specific and adapted for the non-cryogenic separation of industrial gases, and more particularly for the separation of nitrogen by adsorption in gas streams such as air, and also for the purification of hydrogen by adsorption of carbon monoxide (CO) and/or nitrogen (N2), and also to the use thereof especially for the preparation of medical oxygen in oxygen concentrators for respiratory assistance.本發明係關於新型沸石吸附材料以及其尤其用於製備供輔助呼吸用之氧氣濃縮器中的醫療氧氣之用途,該等新型沸石吸附材料特定言之專用於且適用於工業氣體的非低溫分離,且更特定言之用於藉由在諸如空氣之氣流中之吸附來分離氮氣,以及用於藉由吸附一氧化碳(CO)及/或氮氣(N2)來純化氫氣。
