molecular sieve

molecular sieve: 1. Type: 3A,4A 2. Professional manufacturer 3.Hight water adsorption

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.

 

Chemical Formula: 0.4K2O·0.6Na2O·AL2O3·2.0SiO2·4.5H2O

Application1) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadiene) 2) Cracked Gas Drying3) 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 ethanol5) Drying of liquid alcohol6) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.7) Drying of refrigerants

 

Package: 30kg / bag, aluminum foil bag vacuum packaging. 

Attention: Avoid damp and pre-adsorption of organic before running. Or it must be reactivated.
