Introduction
Molecular Sieve 13X is the sodium form of the type X crystal and has a much larger pore opening than the type A crystals. It will adsorb molecules with a kinetic diameter of less than 10 Angstrom (1.0nm) and exclude those larger. It also has the highest theoretical capacity of the common adsorbents and very good mass transfer rates. It can remove impurities too large to fit into a type A crystal and is commonly used to separate nitrogen from oxygen.
Typical Chemical Formula
Na86 [(AlO2)86(SiO2)106].XH2O
Application
Molecular Sieve 13X is mainly used for refinement since it implements simultaneous absorption for bi-molecule and tri-molecule and can be applied for liquefied and gaseous materials on the whole. Main adsorbing target are carbon dioxide, sulfuretted hydrogen and mercaptan including water and it can adsorb all the material whose molecular diameter is less than 10A.
The main uses are as follows.

     1) Air refining (removing CO2 and H2O) 
     2)Removal of mercaptans and hydrogen sulphide from natural gas 
     3)Removal of mercaptans and hydrpogen sulphide from hydrocarbon liquid streams (LPG, butane, propane etc.)
     4)Oxygen PSA (Pressure Swing Adsorption) process
     5)special double glass (removing solvent and grease)

Molecular Sieve Type 13X can be regenerated by evacuating or purging, usually at elevated temperatures. The purge gas temperature must be sufficiently high to bring the molecular sieve to a level of 250°C - 300°C. A properly regenerated molecular sieve can produce dew points below -100°C, mercaptans and CO2 levels 2 ppm.
Storage Package
Prevention against moisture, let it away from water, lube oil, acid and alkali material. Package by 20 kg carton, steel drum, jumbo bag, etc are available.
