Processes using improved rho adsorbent compositions

산소에 대한 동역학적으로 선택적인 RHO 제올라이트를 포함하는 흡착제 조성물을 사용하는 산소를 흡착하기 위한 신규한 공정이 본원에 개시되어 있다. RHO 제올라이트는 비제한적으로 미정제 아르곤 공급물 스트림을 정제하는 것 또는 공기 공급물 스트림으로부터 산소를 분리하는 것과 같은 산소 함유 스트림으로부터 산소를 분리하는 압력 순환 흡착 공정에서 사용될 수 있다. A novel process for adsorbing oxygen using an adsorbent composition comprising a RHO zeolite that is dynamically selective for oxygen is disclosed herein. RHO zeolites can be used in pressure cycling adsorption processes that separate oxygen from oxygen-containing streams, such as but not limited to purifying the crude argon feed stream or separating oxygen from the air feed stream.
