Outlines
ZEOCHEM® 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.
Typical Chemical Formula
Na2O . Al2O3 . 2.5 SiO2 . n H2O
Application
- Removal of CO2 and moisture from air (air pre-purification) and other gases with Z10-02
- Separation of enriched oxygen from air.
- Removal of mercaptans and hydrogen sulphide from natural gas using patented Zeochem technology.
- Removal of mercaptans and hydrpogen sulphide from hydrocarbon liquid streams (LPG, butane, propane etc.) with Z10-01
- Catalyst protection, removal of oxygenates from hydrocarbons (olefin streams)
with Z10-03
- Removal of n-chained compositions from aromatics with Z10-03
- Production of bulk oxygen in PSA units
- Production of medical oxygen in small scale oxygen concentrators
- Special grades are available, such as LiX type: Z10-07; Li-LSX typ Z12-07)
- NEW: ZEOX OII for even faster adsorption and higher adsorption capacity for Medical Oxygen concentrators.
- Special lithium grades, such as LiX Z10-07 and LiLSX Z12-07 can be used in both, bulk and small scale oxygen production.

Regeneration:
ZEOCHEM® 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
13X - Zeolites are available in beads of 0.4 –0.8 mm, 1-2 mm, 1.6-2.6 mm, 2-3 mm,
2.3-3.3 mm, 2.5-5 mm, and as powder PURMOL® 13
