Removal of CO2 and moisture, n-chained compositions, oxygenates from hydrocarbons; Catalyst protection.
Properties of molecular sieve 13X:
Aperture of molecular sieve 13X is the sodium form of the type X crystal that can adsorb any molecular smaller than 10A.
It also has the highest theoretical capacity of the common absorbents and very good mass transfer rates. It is mainly used for absorbing co-catalyst carrier, water and carbon dioxide and hydrogen sulfide gas as well as separation of nitrogen from oxygen.
It is mainly applied in medicine and the air compression system with different professional products according to different applications.

Application of molecular sieve 13X:
- The gas purification and removal of water and carbon dioxide in air separation plant (air pre-purification).
- Drying and desulfurization of natural gas, liquefied petroleum gas and liquid hydrocarbon.
- 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 .
- To further dry other kind of gas.
Conservation of molecular sieve 13X:
1. Room temperature, humidity <90%, non-expose to air directly.
2. Non-contact with water, acid and alkali.
3. Not to expose to the air directly.
