Molecular Sieve: 3A

Type 3A
Composition 0.6 K2O: 0.40 Na2O : 1 Al2O3 : 2.0 ±
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 ~3Å
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.

3A Molecular Sieve

The pore size of 3A molecular sieve is 3A. It does not adsorb any molecular larger
than 3A. According to the industrial application specialties, our products have
the characters of higher adsorption speed, stronger crushing and anti-contaminative
resistance, more cyclic times and longer work-span. All these advantages have
made it come to be the most essential and necessary desiccant in the fields
of the deep drying, refinery polymerization for cracked gasses, ethylene, propylene
and any other non-acidic gasses of liquids in petroleum and chemical industrials.

3A Molecular Sieve Formula
0.4K2O 0.6Na2O Al2O3 2.OSiO224.5H2O

3A Molecular Sieve Typical Applications
1) Dehydration of many kinds of liquids (such as ethanol)
2) Dehydration of air
3) Dehydration of refrigerant
4) Dehydration of natural gas or methane
5) Dehydration of cracked gas, ethylene, propylene or butadiene
