13X Molecular Sieve
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 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:
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 degree C is
required. A properly regenerated molecular sieve can give moisture dew points
below -100 degree 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.
