Molecular Sieve 3A
Minimum Order: 0
Quality/Safety Certification: 0.00
A molecular sieve is a material containing tiny pores of a precise and uniform size that is used as an adsorbent for gases
| 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. |
