The pore size for 5A molecular sieve is about 5A. It can adsorb all kinds of molecular 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:0.70CaO·0.30Na2O·Al2O3·2.0SiO2·4.5H2O 　Technical parameter: Item Unit Target Shape Pellet Sphere Diameter Mm 1.5-1.7 3.0-3.3 2.0-3.0 3.0-5.0 Size % ≥98 ≥98 ≥96 ≥96 Bulk density g/ml ≥0.60 ≥0.60 ≥0.60 ≥0.60 Wear ratio % ≤0.20 ≤0.25 ≤0.20 ≤0.25 Crushing strength N ≥30/cm ≥45/cm ≥30/p ≥60/p Water adsorption % ≥21.5 ≥21.5 ≥21.5 ≥21.5 N-hexane adsorption % ≥14 ≥14 ≥14 ≥14 Packing water % ≥1.5 ≤1.5 ≥1.5 ≤1.5 　　This is the typical parameter for type 5A molecular sieves, different applications of MS require different technical parameters, please contact us to request detail. 　　Applications: Pressure swing adsorption.
