Product Description
4A Zeolite Molecular Sieve Adsorbent for Gas Drying
4A Zeolite Molecular Sieve Adsorbent for Gas Drying

Molecular Sieve type 4A is an alkali alumino silicate; It is the sodium form of the Type A crystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm). XINGFENG type 4A molecular sieve will adsorb most molecules with a kineticdiameter of less than 4 angstroms and exclude those larger. Such adsorbable molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxyde and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.

* Drying and removing of CO2 from natural gas, LPG, air, inert and athmospheric gases, etc. 
Removal of hydrocarbons, ammonia and methanol from gas streams (ammonia syn gas treating)
* Special types are used in the air break units of buses, trucks and locomotives. 
* Packed in small bags, it may be used simply as a packaging desiccant. 

Molecular sieve Type 4A can be regenerated by either heating in the case of thermal swing processes; Or by lowering the pressure in the case of pressure swing processes. 
To remove moisture from a 4A molecular sieve, a temperature of 250 -280°C is required. A properly regenerated 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

4A - Zeolites are available in beads of 1 -2 mm, (10X18 mesh) 2 -3 mm, (8X12 mesh), 2.5 -5 mm, (4X8 mesh) and as powder, and in pellet 1.6", 3.2". 

To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
