Molecular sieve type 3A

 

GENERAL

• 3A-EPG adsorbent, a potassium-exchanged form of the TYPE A molecular sieve, is an alkali metal aluminosilicate.3A-EPG adsorbent will adsorb molecules with critical diameters up to 3 angstroms.
• Chemical formula is K12[(AlO2)12(SiO2)12]XH2O
• 3A-EPG adsorbent can be regenerated for re-use by heating with simultaneous purge or by evacuation.

 

APPLICATION
It can be applied in petrochemical, acetylene and ethanol industry. 3A-EPG is preferred for dehydration of unsaturated hydrocarbon streams such as cracked gas, ethylene and cracked liquid olefins. The small pore size of 3A-EPG essentially prevents co-adsorption of hydrocarbons.

 

FEATURES AND BENEFITS

• High selectivity
• Low attrition loss
• High crush strength
• High H2O capacity
