Introduction
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.
Typical application:
Will absorb, in sequence of absorption rate, argon, krypton, xenon, ammonia, carbon monoxide, C2H4, C2H2, CH3OH, C2H5OH, CH3CN2, CS2, CH3CL, CH3Br, and carbon dioxide.
Formula: 4ANa2OAl2O*2SiO*4H2O

Regeneration
Molecular Sieve 4A can be revived for
reuse and the required factors for revival are temperature and
pressure. To remove the adsorbed moisture and other materials, the
revival condition shall be set up considering the
features of target material and processing environment. The general
revival temperature of Molecular Sieve 4A is about **0°C and it
should not surpass **0°C at maximum.
