Molecular Sieve 4A |
The
pore size for 4A molecular sieve is 4 A0 . It
is mainly used to adsorb water, methanol, ethanol, sulfureted
hydrogen, carbon dioxide, ethylene, propylene, does not
adsorb any larger molecular than 4 A0, and often
used as desiccant in industrials.

Typical
Application :
|
-
Deep
drying of air, natural gas, alkane and refrigerant.
-
Generation
and purification of argon.
- Static
dehydration of electronic element, pharmaceutical and unstable
materials.
-
Desiccant
of paint, dope and fuel etc.
|
4A
molecular sieve is mainly used to make static dehydration
in airtight gas or liquid system, it can remove the moleculars
of ethyl alcohol, hydrogen sulphide, carbon dioxide, ethylene,
acrylica, and also dry the alkane.
