Performance comparison of several zeolite molecular sieves for oxygen production
The principle of pressure swing adsorption oxygen production is to use a pressure swing method to concentrate the oxygen in the air to more than 95% for medical use.
Common zeolites used in oxygen generators are 5A, 13X, and lithium X. Among them, lithium X has the best oxygen production capacity and the highest oxygen production. It is widely used in medical oxygen generators
The adsorption energy of different molecules is as follows
