Abstract

It was experimentally demonstrated that the performance of a medical oxygen concentrator based on rapid pressure swing adsorption (RPSA) process using a LiLSX zeolite was improved [lower bed size factor (BSF) and higher oxygen recovery (R_O)] when the adsorbent exhibited higher selectivity of adsorption of N₂ over O₂. The effects of N₂ selectivity on BSF and R_O as functions of the RPSA process cycle times were found to be complex and nonintuitive. The key properties of a LiLSX zeolite sample for adsorption of N₂ and O₂ (pure and binary gas isotherms, binary selectivity, pure gas isosteric heats, pure gas mass-transfer characteristics, and degrees of adsorbent heterogeneity), which exhibited a relatively higher selectivity of adsorption for N₂ over O₂ compared to a previously reported sample, were measured and used in this study.
