3X Molecular sieve is a sodium form of type X crystal and has a larger pore opening than type 4A molecular sieve. 13X adsorbs molecules with a kinetic diameter of less than 9 Angstrom (0.9nm) and excludes larger molecules.
Which mainly used as catalyze carrier ,coadsorption of CO2 and H2O and H2O , H2O and H2S ,as desiccant for medical and air compressor systems ,and so on.
