3A Molecular Sieve
Description:
The 3A molecular sieve is a kind of alkali metal alumino-silicate. Sometimes, it is also called 3A zeolite molecular sieve.
The aperture of this molecular sieve is 3A. Therefore, 3A zeolite molecular sieve does not adsorb the objects whose molecular diameters are larger than 3Å.
The application characteristics of the 3A 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.
Formula: 2/3K2O·1/3Na2O·Al2O3· 2 SiO2 · 9/2 H2O
Application:
Generally, 3A molecular sieve is the necessary desiccant in petroleum, chemical industry. The specific usages are as follows:
1.This kind of alkali metal alumino-silicate can be used to dry various liquids like ethanol, natural gases, methane gases, refrigerants, etc.
2.The 3A molecular sieve is capable of drying unsaturated hydrocarbon, cracking gas, acetylene, ethylene, propylene, butadiene.
Storage:
1.The 3A molecular sieve should be preserved under room temperature
2.Water, acid, alkali ought to be avoided.
3.Air isolation is necessary for this 3A molecular sieve.
