506HN-1 Catalyst for Deoxygenation Applications
- Deoxygenation of Mixed Gases: Suitable for removing oxygen from various mixed gases, purifying the gas composition, commonly used in gas purification and specialty gas supply industries.
- High-Purity Gas Production: Used to produce high-purity gases in environments requiring extremely low oxygen content, such as semiconductor manufacturing, electronics industry, etc.
- Low Oxygen Environment Applications: Maintains gas purity in processes or production requiring low oxygen levels, applied in metal treatment, welding shielding gases, etc.

Instruction For Use
Load the deoxidizer into the reactor and use inert gas to purge the system of any air.
Introduce pure nitrogen or other inert gases with a space velocity of 150–300 hr⁻¹, while simultaneously heating the reactor. Gradually increase the temperature of the deoxidizer to 420–450°C and maintain the temperature for 1 hour.
Introduce a nitrogen-hydrogen mixed gas containing 10–20% hydrogen with a space velocity of 150–300 hr⁻¹. Due to the heating and the introduction of hydrogen, water vapor will be discharged from the vent. The activation process proceeds in layers along the airflow direction. Once the activated layer moves from one end to the other and no more water vapor is discharged from the exhaust, it indicates that activation is nearly complete. At this point, stop heating, close the hydrogen gas supply, and retain a small flow of nitrogen. After appropriately purging the system, the deoxidizer is ready for deoxygenation.
If the deoxidizer is to be stored, introduce a small flow of nitrogen and allow the system to cool naturally. Once the reactor temperature approaches room temperature, close the nitrogen gas and vent valves, and store the system.
- Deoxygenation Purification
Once activation is complete, the system is ready for operation. Introduce the gas to be purified, and the deoxidizer will begin deoxygenation.
- Regeneration of the Deoxidizer
Once the deoxidizer becomes saturated with oxygen, switch to the regeneration process. The regeneration method follows the same procedure as the activation process.
Note:
Activated or regenerated deoxidizers must not be exposed to air or come into contact with large amounts of oxygen, as this will affect the lifespan of the deoxidizer.
