3A Molecular sieve

A 3A molecular sieve is a kind of molecular sieve (alkali metal alumino silicate) 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 usage life. 3A molecular sieves are the necessary desiccant in petroleum and chemical industries for refining oil, polymerization, and chemical gas-liquid depth drying.

Storage

Room temperature, relative humidity is not more than 90%. Avoid water, acid, alkali, isolate air and closeness are preserved.

 

Regeneration

Methods for regeneration of molecular sieves include pressure change (as in oxygen concentrators), heating and purging with a carrier gas (as when used in ethanol dehydration), or heating under high vacuum. Regeneration temperatures range from 175 °C to 315 °C depending on molecular sieve type.
