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). BESTN type 4A molecular sieve will 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 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
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
