Synthetic zeolite molecular sieves have pore structures and sizes that are consistently precise and uniform. Their size and polarity allow them to adsorb gases and liquids preferentially. Natural Zeolites are highly porous, crystalline solids in the aluminosilicate class. Molecular sieves fall into four main categories: 3A, 4A, 5A, and 13X. The type will depend on the chemical formula and the pore size of the molecular sieve. Molecular sieves are mainly used to dry ethanol. These have many applications that can enhance our everyday life. These have been applied to almost all products in some way. Our company has zeolite molecular sieves 3A and 13X in addition to carbon and UOP molecular sieves.
