Molecular Sieve
Molecular Sieve is a cat – ion exchanged potassium from of A type crystal structure. The potassium ion is larger than sodium ion, is effectively exchanged in basic 4 A type molecular sieve to reduce the pore size ~ 3 A° and it enables selective adsorption depending upon molecular size.
Molecular sieve is used for dehydration of hydrocarbon streams in liquid phase or vapor phase due to high drying efficiency and minimizes the interference of hydrocarbon co-adsorption. Our Molecular Sieve exhibits high resistance to attrition and physical damage during service.
