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 productes 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.
