Molecular Sieve 13X

Molecular Sieve 13X is an alkali metal aluminosilicate; it is the sodium form of the type X crystal structure. It adsorbs molecules with effective diameters small than 10 angstrom (1 nm). it can remove molecules too large to fit into type A molecular siev

  • Product Description
  • Technical Specification

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.


More Details:

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


Application:

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


Storage:

Keep 13X Molecular Sieve in an air tight container until ready for use to avoid unintended moisture adsorption.


Regeneration&Activation:

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.


Packing:


140 kg/drum, 25kg/carton, supersack
