High Quality and Factory Price for 3A/4A/5A/13X/13X APG in Beads and Pellets

Introduction: 

Molecular Sieve 3A is an alkali metal alumino-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 maximises lifetime when dehydrating such molecules.  

Typical Chemical Formula
0.45 K2O. 0.55 Na2O. Al2O3.2 SiO2.4. 5H2O
SiO2: Al2O3 ≈2 

Technical Parameter

Typical Application
1) Drying of unsaturated hydrocarbons (e. G. Ethylene, propylene, butadien)
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 

Regeneration
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.  

Size
3A - Zeolites 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 1.6, 3.2.  

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