3A 4A 5A 13X Zeolite Molecular Sieve For Chemical Agent 2.0-3.0mm, 3.0-5.0mm,4.0-6.0mm
Products Introduction
A 3A molecular sieve is a kind of molecular sieve (alkali metal aluminosilicate) whose aperture is 3 Å.
Sometimes, it is also called 3A zeolite molecular sieve.
Chemical Formula: 2/3K2O•1/3Na2O•Al2O3• 2 SiO2 • 9/2 H2O
Silica-alumina Ratio: SiO2/ Al2O3≈2
Aperture: 3 Å 3A molecular sieves do not adsorb chemicals whose molecular diameters are larger than 3Å. The application characteristics of this molecular sieve include fast adsorption speed, frequent regeneration ability, crushing resistance and pollution resistance. These features can improve its use efficiency and prolong its useful life. 3A molecular sieves are the necessary desiccant in petroleum and chemical industries for refining oil, polymerization, and chemical gas-liquid depth drying.

Attention
1. The product cannot be exposed in the open air and should be
stored in dry condition with air-proof package
2. The product should be regenerated after a certain period of
adsorption. The appropriate regenerated temperature would be better
below 350°C.
