Product Content Description:

Molecular Sieve type 4A (Angstrom) is an alkali alumino 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 adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.
4A is widely used to dry gas and liquid, such as cracked gas, natural gas, refrigent, liquid gas, naphtha, kerosene, diesel oil and transformer oil, etc. It can be also employed to extract, purify argon and desulphurization. It will adsorb, in sequence of adsorption rate, argon, krypton, xenon, ammonia, carbon monoxide, C2H4, C2H2, CH3OH, C2H5OH, CH3CN2, CS2, CH3CL, CH3Br, and carbon dioxide.
