Purification Oxygen Concentrator Adsorbent 5a Molecular Sieve For PSA
Molecular Sieve adsorbents with a pore size of 5 angstrom (5A), 5A molecular sieves are unable to adsorb any molecules or impurities that are smaller than 5A. A calcium form of type A crystalline structure, this particular sieve is an alkali-aluminosilicate that is most commonly used to separate isomerous alkanes from normal alkanes and to co-adsorb moisture and water along with carbon dioxide from gases. In additional 5A molecular sieves are used for gaseous pressure swing adsorption (PSA)—that is to separate particular gases from other gases. The rate of adsorption sequence for 5A molecular sieves is C3-C14, C2H5CL, C2H5Br, CH3L, C2H5NH2, CH2CL2CH2Br2, CHF2CL, CHF3, CF4, (CH3)NH2, B2H6CF2Cl2, CHFCl2, and CF3Cl.
