Molecular Sieve 4A is made from zeolite powder 4A (>70%) and binder. Zeolite powder 4A is generated by reaction of water, sodium hydroxide, sodium silicate and sodium aluminate. Molecular sieve 4A is usually used for in packaging of drugs, electronic components.Since 4A molecular sieve is more easier to be produced than 3A Molecular Sieve, 5A molecular sieve, 13X molecular sieve, it is more economic than other three desiccant. Molecular Sieve 4A have the shape of beads, pallets.
Molecular Sieve 5A is made from zeolite powder 5A (>70%) and binder. Molecular sieve 5A is usually used for separation of the normal and isomerous alkane, co-adsorption of carbon dioxide and moisture, along with pressure swing adsorption (PSA) for gases. Molecular Sieve 5A have the shape of beads, pallets.
Molecular Sieve 13X is made from zeolite powder 13X (>70%) and binder. Molecular sieve 13X is can adsorb aromatics and branched-chain hydrocarbons. Molecular sieve 13X is commonly used in removal of mercaptans, removal of CO2 in cryogenic air separation, etc.
Synonym: Zeolite 13X, Molsive 13X, 13X molecular sieve, 13X-APG
Typical Chemical Formula: Na86[(AlO2)86(SiO2)106].nH2O
CAS NO.: 1318-02-1
Silica-alumina ratio: SiO2/ Al2O3≈2.4
1. Molecular sieve 13X is used in removal of CO2 and moisture from air (air pre-purification) and other gases
2. Molecular sieve 13X is used in separation of enriched oxygen from air
3. Molecular sieve 13X is used in removal of mercaptans and hydrpogen sulphide from hydrocarbon liquid streams such as LPG, butane, propane etc
4. Molecular sieve 13X is used in removal of n-chained compositions from aromatics
Keep 13X Molecular Sieve in an air tight container until ready for use to avoid unintended moisture adsorption.
Molecular sieve 13X can be regenerated either thermal regeneration method(Thermal Swing Adsorption, TSA); To remove moisture from a 13X molecular sieve, a temperature of 200-230℃ (390-570°F) is required. Molecular sieve 13X can also be regnerated by lowering the pressure in the case of pressure swing processes (PSA). A properly regenerated molecular sieve can give moisture dew points below -100℃. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
