Molecular sieve 3A

Molecular Sieve 3A

Chemical Formula:

K8Na4[(AlO2)12(SiO2)12]·XH2O

Introduction:

A-type crystal structure potassium. It is a kind of aluminosilicate of alkali metal. It can adsorb molecules whose critical diameter is not more than 3.

Uses:

widely applied in the drying process of natural gas and petroleum gas, especially the advanced drying of gases like petroleum pyrolysis gas, ethylene, propylene, butadiene and acetylene, liquids like ethanol and acetone. In medical treatment and food industry, it can also be used as drying agent. It is also applied in insulating glass.

Regeneration:

it can be regenerated through the course of improving the temperature. Regeneration temperature is 180-350°C, and regeneration time is 3-6 hours.

Packing:

sealed iron drum 25kg, 50kg, 136kg.

Amount of H2O adsorbed by every 100g of activated molecular sieve under the normal pressure and at 35°C.

Points of Attention:

Packed in sealed iron drum and put in dry place;
PH value for application is 5-11;
It can be use after regenerated if absorbing moisture for being kept for a long time. The maximum regeneration temperature is 600°C.
