Lithium Molecular Sieve
Lithium molecular sieve is high-performance lithium exchanged low silica form of the X-type zeolite with exceptional nitrogen capacity to provide optimal performance in the separation of oxygen from the air in medical oxygen concentrators. The molecular sieve material is developed and designed for the production of up to 95% oxygen-rich airstreams in medical oxygen concentrators with air flows up to 10 liters per minute. There are three mechanisms of adsorption separation: steric hindrance effect, kinetic effect, and equilibrium effect.
Parameters of Lithium Zeolite/Molecular Sieve
Naike Chemical is a professional zeolite molecular sieve manufacturer for oxygen generator, providing various molecular sieve for sale. There are mainly four types of lithium based molecular sieve for oxygen concentrator: NKOX-100, NKOX-101, NKOX-102 and NKOX-103. The parameters of lithium molecular sieve are as follows:

Zeolite Powder for Oxygen Concentrator
Lithium molecular sieve can be used in chemical industry and health care industry.In order to meet the current high requirements of oxygen therapy and reduce disadvantages, zeolite molecular sieve is used in clinic as a new type of medical oxygen chip. Generally speaking, medical molecular sieve oxygen production equipment uses air as raw material, while zeolite molecular sieve (ZMS) is used as adsorbent to produce oxygen by pressure swing adsorption (PSA). The oxygen concentration is usually 93 ±3%.
At present, there are mainly two kinds of zeolite oxygen sieveused in oxygen concentrators in the market: sodium type and lithium type. Naikemolecular sieve company can provide professional PSA Zeolite for oxygen concentrator. Lithium zeolite molecular sieve is more efficient than sodium zeolite molecular sieve, which can greatly reduce the volume of oxygen generator and make the oxygen concentrator smaller and easier to carry.
Molecular Sieve for Oxygen Concentrator Uses
3A: Drying petroleum cracking gas and olefins.
4A: Natural gas drying and alkane separation.
5A: Drying and purification of air, dehydration and desulfurization of natural gas, desulfurization of liquefied petroleum gas and pressure swing adsorption oxygen production and hydrogen production.
5A-DW: Dewaxing,pour point depression and paraffin separation of aviation kerosene and diesel oil.

Features of Lithium Molecular Sieve
Lithium based molecular sieve is a synthetic zeolite of lithium-type crystal structure, large Nitrogen adsorption capacity, high efficiency of oxygen/nitrogen separation.
Thus, gives a facility to use this system in future operations as well.
Lithium based molecular sieve shows high N2/O2 separation under a very low pressure, which lowers the consumption of producing oxygen.
The advantage of on the equilibrium adsorption capacity, and lithium molecular sieve is applies to various VPSA device for oxygen concentrator.
