Brief

Molecular Sieve 13X also has the highest theoretical capacity of the common adsorbents and very good mass transfer rates.Molecular Sieve 13X is commonly used to separate nitrogen from oxygen.


Molecular Sieve 13X Details

Molecular Sieve 13X 
 
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.The pore size is about 10 Å.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.

Typical Chemical Formula

Na2O . Al2O3 . (2.8±0.2) SiO2 . (6~7)H2O
SiO2 : Al2O3 ≈2.6-3.0

Size

molecular sieves 13X 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.

Application

1) Removal of CO2 and moisture from air (air pre-purification) and other gases.
2) Separation of enriched oxygen from air. 
3) Removal of mercaptans and hydrogen sulphide from natural gas.
4) Removal of mercaptans and hydrpogen sulphide from hydrocarbon liquid streams (LPG, butane, propane etc.)
5) Catalyst protection, removal of oxygenates from hydrocarbons (olefin streams).
6) Removal of n-chained compositions from aromatics.
7) Production of bulk oxygen in PSA units .
8)
Production of medical oxygen in small scale oxygen concentrators

Regeneration

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


Attention

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

Packing:

1)25kg carton box. Inner package, vacuumize with plastic bag.
2)150kg gallon iron drum
3)As requirement of consumers
