zeolite 4a molecular sieve is an alkali alumino silicate; it is the calcium form of the Type 4A crystal structure. Type 4A zeolite molecular sieve has an effective pore opening of 4 angstroms (0.4 nm). It will adsorb molecules with a kinetic diameter of less than 4 Angstrom and exclude those larger.
Typical Chemical Formula
Na2O·Al2O3 ·2.SiO2· 4.5H2O
1) Drying and removing of CO2 from natural gas, LPG, air, inert and athmospheric gases, 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.

zeolite 4a molecular sieve 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 type 4A zeolite 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
