Type 5A has an effective pore opening of 5 angstroms (0.5 nm). It will adsorb molecules with a kinetic diameter of less than 5 Angstrom and exclude those larger.It is especially suitable for PSA adsorber applications where it may be used for the separation of normal- and iso- paraffins (C4 to C6 species), in PSA hydrogen purification and in oxygen concentrators. Typical Chemical Formula0.70CaO 0.30Na2O Al2O3 2.0SiO2 4.5H2OSiO2 Al2O3 ≈2  Technical Parameter ItemUnitTechnical dataShape PelletSphereDiametermm1.5-1.73.0-3.32.0-3.03.0-5.0Size ratio up to grade%≥98≥98≥98≥98Bulk densityg/ml≥0.65≥0.65≥0.70≥0.70Wear ratio%≤0.20≤0.40≤0.20≤0.20Crushing strengthN≥30/cm≥45/cm≥30/p≥60/pStatic water adsorption%≥22≥22≥22≥22Water content, as shipped%≤1.5≤1.5≤1.5≤1.5 Application 1) The strong ionic forces of the divalent calcium ion makes it an excellent adsorbent to remove water, CO2, H2S from sour natural gas streams, while minimising COS formation. Light mercaptans are also adsorbed.2) It is also used for the separation of normal- and iso paraffins. 3) Production of high purity N2, O2, H2 and inert gases from mixed gas streams. Regeneration Molecular sieve Type 5A can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes. To remove moisture from a 5A molecular sieve, a temperature of 250-300°C is required. A properly regenerated molecular sieve can give moisture dew poinZeolite 3A For 99.9% Alcohol Purity1.Sphere1-2,2-3,2.5-5mm2.Pellet1.6,3.2"3.ISO 900120084.Typeadsorbent Zeolite Wholesale 3A For 99.9% Alcohol Purityis an alkali metal alumino-silicate; it is the potassium form of the type A crystal structure. Type 3A has an effective pore opening of about 3 angstroms (0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers; and this maximizes lifetime when dehydrating such molecules. Typical Chemical Formula0.4K2O 0.6Na2O Al2O3 2.OSiO2 4.5H2OSiO2 Al2O3 ≈2 Technical Parameter ItemUnitTechnical dataShape PelletSphereDiametermm1.5-1.73.0-3.31.7-2.53.0-5.0Size ratio up to grade%≥98≥98≥98≥98Bulk densityg/ml≥0.65≥0.65≥0.70≥0.70Wear ratio%≤0.20≤0.25≤0.10≤0.10Crushing strengthN≥45/cm≥60/cm≥30/p≥70/pStatic water adsorption%≥20≥20≥20≥20Ethylene adsorption%≤3.0≤3.0≤3.0≤3.0Water content, as shipped%≤1.5≤1.5≤1.5≤1.5 Typical Application 1) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien) 2) Cracked Gas Drying3) Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required. 4) Drying of highly polar compounds, such as methanol and ethanol5) Drying of liquid alcohol6) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.7) Drying of refrigerants RegenerationMolecular sieve Type 3A can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes. To remove moisture from a 3A molecular sieve, a temperature of 200-230°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C.The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process. Size 3A - Zeolites are available in beads of 1-2 mm, (10x18 mesh) 2-3 mm, (8x12 mesh) , 2.5-5 mm, (4x8 mesh) and as powder, and in pellet 1.6", 3.2". AttentionTo avoid damp and pre-adsorption of organic before running, or must to be reactivated.
