13X Molecular Sieve
13X Molecular Sieve

Supply higher quality Molecular Sieve 13X with competitive price. Commonly used to seperate nitrogen from oxygen.  

13X Molecular sieve is a sodium form of type X crystal and has a larger pore opening than type 4A molecular sieve. 13X adsorbs molecules with a kinetic diameter of less than 9 Angstrom (0.9nm) and excludes larger molecules.Which mainly used as catalyze carrier ,coadsorption of CO2 and H2O and H2O , H2O and H2S ,as desiccant for medical and air compressor systems ,and so on.

 Typical Chemical FormulaNa2O . Al2O3 . (2.8±0.2) SiO2 . (6~7)H2O SiO2 : Al2O3 ≈2.6-3.0

 Application  Removal of CO2 and moisture from air (air pre-purification) and other gases. Separation of enriched oxygen from air.   Removal of mercaptans and hydrogen sulphide from natural gas. Removal of mercaptans and hydrpogen sulphide from hydrocarbon liquid streams (LPG, butane, propane etc.) Catalyst protection, removal of oxygenates from hydrocarbons (olefin streams). Removal of n-chained compositions from aromatics. Production of bulk oxygen in PSA units . Production of medical oxygen in small scale oxygen concentrators 

 Regeneration: molecular sieve Type 13X 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 13X molecular sieve, a temperature of 250-300°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C, or mercaptan or CO2 levels below 2 ppmv.The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process   Size 13X - 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.
