Zeolite Molecular Sieve
A molecular sieve, also called zeolite, is a material with pores (very small holes) of uniform size. These pore diameters are similar in size to small molecules, and thus large molecules cannot enter or be adsorbed, while smaller molecules can.
Depends on zeolite molecular sieve average pore size, the molecular sieve can be classified into molecular sieve 3A, molecular sieve 4A, molecular sieve 5A, molecular sieve 10X and molecular sieve 13X and others. There are also some specially designed molecular sieves by exchanging the metal ion and silica alumina ratios.
With these special properties, the zeoltie molecular sieve are widely used in various areas such as air dehydration, gas dehydration, ethanol dehydration, air break system, refrigerant dehydration, insulating glass system, PSA hydrogen purification, etc.
