The pore size for 4A molecular sieve is 4A. It is mainly used to adsorb water, methanol, ethanol, sulfureted hydrogen, carbon dioxide, ethylene, propylene, argon, krypton, xenon, ammonia, carbon monoxide, C2H4, C2H2, CH3OH, C2H5OH, CH3CN2, CS2, CH3CL, CH3Br, and carbon dioxide. does not adsorb any larger molecular than 4A, and often used as desiccant in industrials.
The advantages of our high quality 4A molecular sieve are consistent adsorption speed, and higher contamination resistance, stronger crushing increasing cyclic times that provide an extended product life. 4A Molecular Sieve is primarily for removing moisture from liquefied and gaseous materials.
Formula: Na2O·Al2O3·2.0SiO2·4.5H2O
