Indroduction:
Molecular Sieves are crystalline metal alumino silicates having a three dimensional interconnecting network of silica and alumina tetrahedra. Natural water of hydration is removed from this network by heating to produce uniform cavities which selectively adsorb molecules of a specific size.
A 4 to 8-mesh sieve is normally used in gasphase applications, while the 8 to 12-mesh type is common in liquidphase applications. he powder forms of the 3A, 4A, 5A and 13X sieves are suitable for specialized applications.
Molecular Sieve 3A is one kind of alkali metal alumino-silicate. Sometimes, it is also called 3A zeolite molecular sieve. The aperture of this molecular sieve is 3A. Therefore, It does not adsorb the objects whose molecular diameters are larger than 3Å. 3Amolecular sieve's formula is 2/3K2O•1/3Na2O•Al2O3• 2 SiO2 • 9/2 H2O. 3A molecular sieve desiccant is the necessary desiccant in petroleum, chemical industry
