Details

Typical Chemical Formula:

Na12 [(AlO2) 12(SiO2) 12] · X H2O


Molecular Sieve 4A made by 4A zeolite powder with attapulgite clay, it is sodium form of type A zeolite crystal structure with an effective pore opening of about 4 angstroms (0.4 nm).


Molecular Sieve 4A can adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger. Such adsorbable molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxide and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.


Molecular Sieve 4A produced by Luoyang Jalon exhibits high mass transfer efficiency, high mechanical strength and durability.


Application:

-Molecular sieve 4A can be used for drying and removing of CO2 from natural gas, LPG, air, etc.

-Molecular sieve 4A can be used for removal of hydrocarbons, ammonia and methanol from gas streams (ammonia syn gas treating).

-Molecular sieve 4A can be used in dehydration of refrigerant and air in the air break units of buses, trucks and locomotives.

-Molecular sieve 4A can be packed in small bags for packing desiccant for foods, electronics elements, drugs etc.

Storage:

Keep 4A Molecular Sieve in an air tight container until ready for use to avoid unintended moisture adsorption.


Regeneration & Activation:

Molecular sieve 4A can be regenerated or activated either thermal regeneration method(Thermal Swing Adsorption, TSA); To remove moisture from a 4A molecular sieve, a temperature of 200-230°C (390-570°F)is required. Molecular sieve 4A can also be regnerated or activated by lowering the pressure in the case of pressure swing processes (PSA). A properly regenerated or activated molecular sieve can give moisture dew points below -100°C. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
