Abstract�� The effects of some main factors,such as the species of molecular sieve,exchange time,pressure equalization process,ratio of height to diameter,the volume of tank on the process of small-scale pressure swing adsorption(PSA) oxygen generating are discussed experimentally.The experimental results show that different species of molecular sieve have different productivity and LiX is best;using LiX molecular sieve can decrease the volume of oxygen concentrator and improve the characteristics;with the increase of exchange time,the oxygen purity increases in the beginning and then decreases,the optimal exchange time is defined by experiment.The pressure equalization may improve the oxygen purity and recovery,the oxygen purity and recovery of the pressure equalization process in absorber's two-lets are the biggest.Increasing the ratio of height to diameter of the absorber can improve the oxygen purity,but it is not good if the ratio is too big.Increasing the volume of tank can also improve the oxygen purity.
