3A Micron Sieve Bead

2 Pound Bag

Composition 0.6 K2O: 0.40 Na2O : 1 Al2O3 : 2.0 0.1SiO2 : x H2O

Description The 3A form is made by substituting potassium cations for the inherent sodium ions of the 4A structure, reducing the effective pore size to ~3, excluding diameter >3, e.g., ethane.

Major Applications Commercial dehydration of unsaturated hydrocarbon streams, including cracked gas, propylene, butadiene, acetylene; drying polar liquids such as methanol and ethanol. Adsorption of molecules such as NH3 and H2O from a N2/H2 flow. Considered a general-purpose drying agent in polar and nonpolar media.
