Lithium molecular sieve
CHEMXIN lithium based molecular sieve series are special used in PSA/VPSA system. It has the characteristics of high N2/O2 selectivity, high N2 adsorption capacity. Lithium zeolite N2 adsorption capacity is 2 times higher than sodium zeolite.At the same time, Lithium zeolite has better wear resistance and longer working life.
