Progress of modified adsorbent and pressure swing adsorption for oxygen production in China
摘要
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.关键词
