High purity inert gas deoxygenation catalysts are
typically platinum or palladium-based precious metal catalysts supported on materials like alumina, which remove trace oxygen from inert gases like nitrogen or argon
.
The process works by adding a small amount of hydrogen to the inert gas stream and passing it over the heated catalyst, where the hydrogen and oxygen react to form water, which is then removed.
How it works
-
Catalytic reaction:Oxygen () in the inert gas reacts with added hydrogen () over the catalyst to form water () .
-
Product removal:The water vapor is then removed from the gas stream, typically by cooling and condensation, sometimes followed by a drying system like molecular sieves.
-
Efficiency:The reaction can proceed efficiently, even at or near room temperature, and a slight excess of hydrogen is used to ensure the final product has extremely low oxygen content (e.g., less than 10 PPM).
Types of catalysts
-
Palladium-based:
Often used for deoxygenation at or near room temperature and are highly efficient for a variety of inert gases.
-
Platinum-based:
Can also be used and may be optimal for certain feedstocks, such as those containing sulfur.
-
Support material:
Commonly supported on alumina
(
) spheres, pellets, or extrudates.
Common applications
- Semiconductor manufacturing : Ensures the high purity gases required for sensitive processes.
- Electronics industry : Maintains the quality of gases for production environments.
- Chemical synthesis: Produces high-purity chemicals and intermediates.
- Polymer processing: Enhances the stability and properties of polymers.
- Materials science : Enables the creation of oxygen-sensitive materials.
-
Metal treatment and welding
:
Provides shielding gases with low oxygen content.
