Product Short Description: Absorbent and Catalyst
Product Description:

The pore size for 5A molecular sieve is about 5Ǻ. 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.

MOLECULAR SIEVE 5A
 
Divalent calcium ion is exchanged in place of sodium cation in -4A crystals which gives oire apertures of -5Ao. 5A molecular sieve exclude molecules of effective diameter >5A0, e.g., all 4-carbon rings, and iso-compounds.
 
Molecular sieve 5A adsorbs n-paraffin irrespective of chain lenght and not the branched chain hydrocarbon. Hence it is uesed for specific applications like separations of normal from branched chain paraffin. 5A has excellent drying capacity with simultaneously removing other impurities such as carbon dioxide, hydrogen sulfide. Our molecular sieve exhibits high resistance to attrition and physical damage during serivce.
