Themolecular sieve is a cubic aluminosilicate compound with cubic lattice. Molecular sieve has a uniform microporous structure, its pore size uniform size, these holes can be small molecular weight adsorption to the cavity of the internal and polar molecules and unsaturated molecules have a preferential adsorption capacity, which can be different degrees of polarity, Saturated degree of different molecular size and different boiling point of the molecules separated, that is, with "screening" the role of molecules, so called molecular sieve. As the molecular sieve has the advantages of high adsorption capacity and strong thermal stability, the molecular sieve has been widely used.

Hand & Storage Recommendation
Molecular Sieve should be handled to avoid generation of dusty conditions at the workplace. Storage in a dry
warehouse is recommended. Open packages should be resealed to prevent contamination and
adsorption of water or other gases and vapors. The material in bag-in-box should be used within 12
months,while bag-in-steel drum should be used within 24 months.
RegenerationTo achieve good operating performance and long life as much as possible, after a certain period of time use must be regenerated .
After correct molecular sieve regeneration , make it get the low attenuation of mechanical properties and adsorption
There are two basic approaches:
Generally used in the preheating gas heating, purge molecular sieve to about 200 º C, and stripping down the adsorbate .
Usually used in the gas phase adsorption process.Maintain a constant temperature adsorbent and by reducing
pressure and backing purge inert gas , to remove the adsorbate.
