Abstract: Developing new adsorbents and PSA processes is an important way to improve performance
of PSA devices. In this paper, progress of modified adsorbent and new processes of PSA producing
oxygen are reviewed. LI-LSX or LSX exchanged with Li and other ions has ideal separation
performance, but such adsorbents have problems of low ion exchange utilization and high cost
Preparation of other single or multi-ions modified adsorbents is relatively simple, but the disadvantages
are low separation factor and high cost. Optimization process of modified PSA for oxygen production
based on cycle step cannot provide guide for industrial oxygen devices because of laboratory scale data
and less in-depth study. Rapid PSA and duplex PSA processes have broad development prospect for
oxygen production, and should be paid enough attention. Moreover, multi-stage and coupled PSA
processes have broad application prospect, but they have problems of complex process and high energy
consumption
