4A Type Molecular Sieve

Detail

Products introduction:

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). 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.

Typical Application

a) Drying and   removing of CO2 from natural gas, LPG, air, inert and   atmospheric gases, etc.   

b) Removal of hydrocarbons, ammonia and methanol from gas streams   (ammonia syn gas treating)  

 c) Special types are used in the air break units of buses, trucks and   locomotives.   

d) Packed in small bags, it may be used simply as a packaging desiccant.

 Regeneration
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

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