Product Description

Product Description

4A  Molecular Sieve Drying agent for pyrolysis gas and alkene

4A Molecular Sieve
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 ang stroms (0.4nm). 4Amolecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms andexcude 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.

Applications

Typical Application

1) Drying removing of CO2 from natural gas, LPG, air, inert and athmospheric gased, etc
2) 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 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.


Size:
4A-Zeolites are available in beads of 1-2 mm, (10x18mesh) 2-3 mm,(8xl2 mesh),
2.5-5 mm,(4x8 mesh) and as powder, and in pellet 1.6",3.2"
