3A molecular sieve is an alkali metal aluminosilicate, sometimes also known as 3A zeolite molecular sieve.
Chemical formula: 2/3K2O · 1/3Na2O · Al2O3 · 2SiO2 · 9/2H2O
Effective pore size: approximately 3 Å (1 Å=0.1 nanometers);
The pore size of 3A molecular sieve is 3 Å; It is mainly used for adsorbing water and does not adsorb any molecules with a diameter greater than 3 Å. According to its industrial application characteristics, molecular sieves have fast adsorption speed, regeneration times, crush strength, and anti pollution ability, which improves the utilization efficiency of molecular sieves and extends their service life. It is a necessary desiccant for gas-liquid phase deep drying, refining, and polymerization in the petroleum and chemical industries.
