3A Molecular Sieve的详细介绍
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.

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)
