506HO type dehydrogenation catalyst
This catalyst is a noble metal/oxide system dehydrogenation agent, primarily used for hydrogen removal purification of inert gases such as nitrogen and argon. For example, after inert gases with high oxygen content (0.5–2%) undergo deoxygenation by hydrogenation, the excess hydrogen is removed to obtain high-purity gas free of both oxygen and hydrogen. Alternatively, excess oxygen operation can be performed to remove excess oxygen, with the ultimate goal of achieving purified gas with neither hydrogen nor oxygen.

Service life：≥3 years
Principle：
Hydrogen in the inert gas reacts with the "solid" oxygen on the catalyst to form water, thereby achieving hydrogen removal. When the "solid" oxygen on the catalyst is consumed, oxidation regeneration can be achieved by introducing oxygen at room temperature, allowing for repeated use.
Instructions for Use：
1. Load the HO catalyst uniformly into the reactor, and introduce inert gas to completely displace the air from the system.
2. Introduce inert gas at a space velocity of 150–200hr-1 .
3. Heat the reactor to raise the catalyst temperature to 180–200℃. Once the temperature is stabilized, introduce the normal gas flow for dehydrogenation purification.
Dehydrogenation Agent Regeneration：
When the "solid" oxygen on the HO type dehydrogenation agent is gradually consumed during the dehydrogenation reaction, the dehydrogenation agent requires regeneration by introducing oxygen. Introduce an inert gas mixture with an oxygen content of ≤5% at a space velocity of 300 hr-1 . Monitor the outlet oxygen content using an oxygen analyzer. When the outlet oxygen content rises from a low level to approximately the original oxygen content of the nitrogen, the oxygen pretreatment is complete (the pretreatment time varies depending on the amount of dehydrogenation agent used, generally taking several hours). Close the gas supply valve and place on standby.
※ Note:
1. The top layer inside the deoxygenation tower shall be covered with inert ceramic balls approximately 20cm thick, spread evenly.
2. The gas flows through the deoxygenation tower from top to bottom.
