XINTAO Molecular sieve 3A



Molecular Sieve 3A is an alkali metal alumina-silicate; it is the potassium form of the type A crystal structure. Type 3A has an effective pore opening of about 3 angstroms (0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers; and this maximizes lifetime when dehydrating such molecules.

Typical Chemical Formula

0.45 K2O . 0.55 Na2O . Al2O3 . 2 SiO2 . 4.5H2O
SiO2 : Al2O3 ≈2

Typical Application

1) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadiene)
2) Cracked Gas Drying
3) Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.
4) Drying of highly polar compounds, such as methanol and ethanol
5) Drying of liquid alcohol
6) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
7) Drying of refrigerants


XINTAO molecular sieve Type 3A can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes.
To remove moisture from a 3A molecular sieve, a temperature of 200-230°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.


3A – zeolite are available in beads of 1-2 mm, (10x18 mesh) 2-3 mm, (8x12 mesh) , 2.5-5 mm, (4x8 mesh) and as powder, and in pellet 1/16inch 1/8inch


To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
