Product Description
3A bar molecular sieve
3A molecular sieve is a kind of alkali metal silica aluminate, it is also called 3A zeolite molecular sieve.
Chemical formula:⅔K20-⅓Na20-AL2O3.2SiO2.9/2H2O, effective pore size about 3A, mainly used for adsorption of water, not adsorption of any molecule with a diameter greater than 3A, according to the characteristics of industrial applications, it has fast adsorption speed, regeneration times, anti-crushing strength and anti-pollution ability, high High utilization efficiency, long service life, etc. It is the desiccant necessary for deep drying, refining and polymerization of gas-liquid phase in petroleum and chemical industry.

Molecular sieve 4A
The effective pore opening of molecular sieve 4A is 4 Angstrom. It can adsorb water, methanol, ethanot sulfur compounds, carbon dioxide ect. It can be used for various application.
Molecular sieve 5A
The effective pore opening is 5 Angstrom. With good adsorption selectivity and high adsorption speed, a typical application for SA is removal of the impurities from synthesis gas to obtain high purity hydrogen by PSA process.
Molecular sieve 13X
The effective pore opening is 10 Angstrom. It is used for gas deep drying, removal of water and CO2 in cryogenic air separation system. It can adsorb any molecules which can be adsorbed by 3A, 4A, SA. It also can adsorb the molecules with large critical diameter.
