Type 3A Molecular Sieve
K12[(AlO2)12(SiO2)12] · X H2O--Molecular
Sieve Type 3A, the potassium form of the Type A Crystal structure, is an alkali metal alumino-silicate. Available in powder and pellets for commercial
dehydration of unsaturated hydrocarbon streams such as cracked gas, propylene, butadiene and acetylene. Type 3A is also used for drying polar liquids such
as methanol and ethanol.
