Molecular sieve 3A does not adsorb any molecularlarger than 3A according to the industrial application specialties, we endue our products with the characters of higher adsorption speed, stronger crushing and anti-contaminative resistance, more cyclic times and longer work-span. All these advantages have made it come to be the most essentialAnd necessary desiccant in the fields of the deep drying, refinery polymerization for cracked gasses, ethylene, propylene and any other non-acidic gasses of liquids in petroleum and chemical industrials.
Molecular sieve 4A can mainly used to adsorb water, methanol, ethanol, sulfureted hydrogen, carbon oxide, ethylene, propylene, does not absorb any larger molecular than 4A, and often used as desiccant in industries.
Molecular sieve 5A can adsorb all kinds of molecular smaller than this size. It is mainly used in the normal and isomerous alkane; pressure swing adsorption (PSA) for gases; co-adsorption of moisture and carbon dioxide.
Molecular sieve 13X (10A), mainly used as catalyze carrier, coadsorption of CO2 and H2O and H2S, as desiccant for medical and air compressor systems, and can be adjusted to fit other various applications.
