Send Message Request a Quote

5A molecular sieves are a calcic type A aluminosilicate crystal that are used to adsorb molecules with a critical diameter less than 5 Å, and a molecular formula of Ca4.5•Na3[•(AlO2)12•(SiO2)12.]XH2O.

Application The separation of n-alkanes and isoalkanes. The drying and refining of air, petroleum, natural gas, and other industrial gas. Separation of O2 and N2. PSA hydrogen production and hydrogen purification.

Features
5A molecular sieves can adsorb any molecule whose diameter is less than its pore diameter, and is usually referred to as a calcic molecular sieve. Not only does it have all the functions of a 3A and 4A molecular sieve, it can also adsorb C3-C4 n-alkanes, chloroethane, bromoethane, butanol and others. It can also be used for the separation of n-alkanes and isoalkane, PSA separation, and the co-adsorption of H2O and CO2.
