Molecular sieve 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 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.

Application
1) Drying and removing of CO2 from natural gas, LPG, air, inert
and athmospheric gases, etc
2) Â Removal of hydrocarbons, ammonia and methanol from gas
streams (ammonia syn gas treating)
3) Special types are used in the air break units of buses, trucks
and locomotives
4) 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
******0°C is required. A properly regenerated molecular sieve can
give moisture dew points below ***0°C.
The outlet concentrations on a pressure swing process will depend
on the gas present, and on the conditions of the process
Size
4A - Zeolites are available in beads of **2 mm, (*0x*8 mesh)
**3 mm, (8x*2 mesh) , 2.**5 mm, (4x8 mesh)Â and as powder,
and in pellet 1.6", 3.2".
Attention
To avoid damp and pre-adsorption of organic before running, or
must to be reactivated.
