3A Molecular Sieve is a potassium form of aluminosilicate.The Molecular Sieve will adsorb molecules which have a critical diameter less than three angstrom (He , H2 & CO)
Molecular Sieve 3A is cation exchanged potassium form of A type crystal structure. The potassium ion being larger than sodium ion, is effectively exchanged in basic 4A type Molecular Sieve to reduce the pore size to 3 angstrom , and it enables selective adsorption depending upon molecular size.
Molecular Sieve 3A is used for dehydration of hydrocarbon streams in liquid phase or vapour phase due to high drying efficiency , and minimizes the interface of hydrocarbon co-adsorption. Our Molecular Sieve, being spherical in shape produces uniform packing and adsorbate diffusion in the adsorber, also exhibits high resistance to attrition and physical damage during service .
