Molecular Sieves are artificial crystal silicon aluminate, based on the crystal size of the internal cavity of the adsorption or exclusion of molecules of different substances, which is vividly called "molecular sieve". Outstanding performance: adsorption capacity, selective adsorption and separation, catalytic activity , ion exchange and so on. Molecular Sieves Application: 3A Used in Dehydration of many kinds of liquids (say ethanol). Dehydration of air. Dehydration of refrigerants. Dehydration of natural gas or methane. Dehydration of cracked gas, ethylene, propylene or butadiene. 4A Used in deep drying of air, natural gas, alkanes and refrigerants. Generation and purification of argon. Static dehydration of electronic element, pharmaceutical and unstable materials. Desiccant for paint, and fuel etc. 5A Used in adsorption in various humidity and vapor pressure conditions. Removal of water and carbon dioxide from air. 13X Used in purification and removal of H2O, CO2, H2S. Dehydration and desulfuration of natural gas, liquid petrol gas and liquid alkane. Drying of common gases. Removal of H2O from air for air cryco-separaton application.
