LiX molecular sieve improve performance of PSA and VPSA oxygen generator for air consumption and saving-energy.China Carbon Molecular Sieve Co., Ltd. has long been engaged in the research and produce Lithium molecular sieve for oxygen production. Using LiX molecular sieve can decrease air consumption and saving-energy and improve the performance. The experimental results show that different species of molecular sieve have different oxygen productivity， LiX molecular sieve is best； For LIX zeolite with excellent adsorption performance, the exchange degree of Li should be Li > 95%, and the higher is the exchange degree, the LiX molecular sieve performance are better.
