4A Molecular Sieve
The pore size for 4A molecular sieve is 4A. It is mainly used to adsorb water, methanol, ethanol, sulfureted hydrogen, carbon dioxide, ethylene, propylene, does not adsorb any larger molecular than 4A, and often used as desiccant in industrials.
Formula: Na2O·Al2O3·2.0SiO2·4.5H2O
