Product Readme: 1.3A molecular sieve The pore size of 3A molecular sieve is 3A. It mainly adsorbs water and does not adsorb any molecular larger 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 essential and 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. Formula:0.4K2O 0.6Na2O Al2O3 *****2 4.5H2O Typical applications: Dehydration of many kinds of liquids (say ethanol) Dehydration of air Dehydration of refrigerant Dehydration of natural gas or methane Dehydration of cracked gas, ethylene, propylene or butadiene 2.4A molecular sieve The pore size for 4A molecular sieve is 4A. It is mainly used to adsorb water, methanol, ethanol, sulfureted hydrogen, carbon dioxide, ethylene, propylene, and does not adsorb any larger molecular than 4A include propane. Its selective water adsorption is higher than any other molecules. And it is the most common used desiccant in industrials. Formula:Na2O�Al2O3�2.0SiO2�4.5H2O Typical applications: Deep drying of air, natural gas, alkane and refrigerant Generation and purification of argon Static dehydration of electronic element, pharmaceutical and unstable materials Desiccant for paint, dope and foul 3.5A molecular sieve The pore size for 5A molecular sieve is about 5A. It can adsorb all kinds of molecules smaller than this size. It is mainly used in separation of the normal and isomerous alkane; pressure swing adsorption (PSA) for gases; co-adsorption of moisture and carbon dioxide. Based on the industrial application specialties, we have produced out our own PSA molecular sieve products, which have better selective adsorb ability and more rapid adsorption speed, being the elaborated products, it could suitable for gases generation and concentration PSA plants of any sizes and any types in the world. Formula:0.*0CaO�0.*0Na2O�Al2O3�2.0SiO2�4.5H2O Typical applications: Pressure swing adsorption Removal of water and carbon dioxide from air 4.*3X molecular sieve The pore size for *3X molecular sieve is about *0A. It can adsorb any molecular smaller than *0A, mainly used as catalyze carrier, coadsorption of CO2 and H2O, H2O and H2S , as desiccant for medical and air compressor systems, and can also be adjusted to fit other various applications. Formula:Na2O. Al2O3 2.*5SIO2. *****2O Typical applications: Purification and removal of H2O and CO2 Dehydration and desulfuration of nature gas, liquid petrol gas and liquid alkane Deep dry of common gases
