Supply 13X Zeolite Molecular Sieves

 

 

KANGYU 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 9 Angstrom (0.9 nm) 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.

 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:
KANGYU 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 ppm.
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 1.6mm, 3.2mm.

 Attention
 To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
