Molecular Sieve 4A

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

*This is the typical parameter for type 4A molecular sieves, different applications of MS require different technical parameters, please contact us to request detail.
Recommended Application:
·Dehydration of electronic element, pharmaceutical, food, etc.
·Drying and removing of CO2from natural gas, LPG, air, inert and atmospheric gases, etc.
·Removal of hydrocarbons, ammonia and methanol from gas streams(ammonia syn gas treating)
