Molecular Sieve type 4A (Angstrom) is an alkali alumina silicate, obtained through synthesis of type A zeolite in sodic form. 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). Galaxychem type 4A molecular sieve will absorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.
Formula: Na2O·Al2O3·2SiO2·4.5H2O  
Silica-alumina Ratio: SiO2/ Al2O3≈2
Aperture: 4A

Will absorb in sequence of absorption rate, argon, krypton, xenon, ammonia, carbon monoxide, C2H4, C2H2, CH3OH, C2H5OH, CH3en2, CS2, CH3CL, CH3Br, and carbon dioxide.
1. Deep drying of air, natural gas, alkane and refrigerant.
2. Generation and purification of argon.
3. Static dehydration of electronic element, pharmaceutical and unstable materials.
4. Desiccant of paint, PU Plastic, dope and fuel etc.

1. Removing the moisture:
You May use the dry gas like nitrogen, the air, the hydrogen, the saturated hydrocarbon and heat the gas up to 150-320 ºC.Firstly you need let the hot gas purge through the molecular sieve bed with the pressure of 0.3-05kg/m2 for 3 to 4 hours. Then change to dry cold gas for 2-3 hour, at last you need isolate the molecular sieve from air and cool it to room temperature.
2. Removing the organics:
You can use the water vapor to take the place of organics, then use the method 1.
You can also use the hot water vapor or inner gas pass through the molecular sieve under the temperature of 200-350ºC (couldnt use the gas which will explore when to mix with the adsorbed organics).
3. Removing the gas
You can reduce the pressure to regenerate the molecular sieve.
