产品详细信息

1. Product Description
3A Molecular Sieve is an alkali metal alumino-silicate; it is the potassium form of the typ A crystal structure. 3A Molecular Sieve 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.

2. Typical Chemical Formula
0.4K₂O 　0.6Na₂O　 Al₂O₃ 　2.OSiO₂ 　4.5H₂O

4. Typical Application

(1)Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien) Cracked Gas Drying
(2)Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.
(3)Drying of highly polar compounds, such as methanol and ethanol
(4)Drying of liquid alcohol with Z3-01 / 1-2 mm beads Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
(5)Drying of refrigerants (e.g. R22, R134a etc)
