506HN Deoxidizer — Room-Temperature Deoxygenation, a Reliable Solution for High-Purity Gas Purification
Release time:
Sep 18,2026
In the field of gas purification, catalytic deoxygenation via hydrogenation is a common route: hydrogen and oxygen react in the presence of a catalyst to form water, thereby removing oxygen. However, this route has an implicit precondition—either the introduction of hydrogen into the gas is acceptable, or a subsequent dehydrogenation step is available.
For scenarios such as nitrogen and inert gases, where hydrogen cannot be introduced or where its introduction is undesirable, deoxygenation requires a different approach. Our Model 506HN Deoxidizer takes exactly another path: it does not rely on hydrogenation but directly absorbs oxygen.
Chemical Adsorption Deoxygenation: A Different Principle
Unlike catalytic deoxygenation via hydrogenation, the Model 506HN Deoxidizer is a chemical adsorption-type product based on a noble metal/oxide system. Its working principle is that oxygen impurities in the feed gas are directly absorbed by the deoxidizer. Once absorption is saturated, hydrogen is introduced for reduction and regeneration, allowing repeated use. This mechanism makes it particularly suitable for oxygen removal and purification of nitrogen, carbon dioxide, argon, helium and other inert gases, as well as other industrial gases.
Works at Room Temperature with Low Regeneration Temperature
A major feature of the Model 506HN Deoxidizer is room-temperature deoxygenation—it can start working without additional heating, and its performance is even better at elevated temperatures, with an upper temperature limit of up to 350°C. The regeneration temperature is only 180–250°C, providing a wide operating window and low energy consumption.
In terms of performance, after purification with this product, the residual oxygen content can be controlled at ≤0.5 ppm, and the deoxygenation capacity reaches 8–15 L/kg. It is suitable for operating conditions where the oxygen content in the feed gas is ≤1000 ppm, and its service life under normal operating conditions is ≥3 years.
Simple Operation with Cyclable Activation and Regeneration
Before use, the Model 506HN Deoxidizer needs to be activated: load the deoxidizer into a reactor, use an inert gas to purge air from the system, then introduce pure nitrogen or an inert gas and raise the temperature to 180–250°C for activation. In industrial applications, a nitrogen-hydrogen mixed gas containing 10–20% hydrogen can be introduced to complete activation. After activation, the gas to be purified can be introduced to begin deoxygenation. After oxygen absorption saturation, hydrogen reduction regeneration is carried out according to the same procedure, restoring activity for repeated use.
Serving High-Purity Gas Purification Needs
As industries such as electronics, semiconductors, metallurgy, and chemicals continue to raise their requirements for high-purity gas quality, deep gas deoxygenation has become an important part of ensuring product quality and production safety. With the comprehensive advantages of room-temperature deoxygenation, large oxygen absorption capacity, low regeneration temperature, and repeated use, the Model 506HN Deoxidizer provides a mature and reliable option for gas purification processes in various industries.
