HT-2 is a manganese-based, transition-metal-oxide solid catalyst engineered for trace oxygen removal from inert and process gas streams. It is designed for industrial gas purification units where residual O₂ must be strictly reduced before the gas contacts oxygen-sensitive downstream equipment or chemical processes.
Operating via a direct solid-phase catalytic reaction, HT-2 removes micro-quantities of oxygen without requiring quantitative hydrogen addition to the feed gas, eliminating the safety hazards of flammable gas mixing. Under normal operating parameters, the material functions in a continuous single-pass mode without requiring routine thermal or chemical regeneration.

Core Product Advantages
Trace O₂ Reduction Efficiency: Engineered specifically to pull residual oxygen down from minor contamination levels to ultra-low thresholds without slipping performance under minor feed fluctuations.
Elimination of Stoichiometric Additives: Operates via a self-contained solid-phase redox mechanism, removing the infrastructure, instrumentation, and explosion risks associated with external hydrogen-injection skids.
Zero-Regeneration Simplicity: Functions continuously in single-pass mode, eliminating the downtime, energy consumption, and valve maintenance associated with thermal swing or chemical regeneration towers.
Customizable Physical Morphology: Available in various extrudate diameters and spherical geometries to optimize the balance between reaction kinetics and bed pressure drop.
Targeted Gas Purification Applications
High-Purity Nitrogen (N₂) Purification
Eliminates trace O₂ in electronics manufacturing, blanketing systems, and protective atmospheres.
Argon (Ar) Shielding Gas Processing
Prevents high-temperature oxidation defects in metal welding, powder metallurgy, and alloy production.
Hydrogen (H₂) Stream Polishing
Cleans accidental oxygen traces from cooling loops and hydrogenation carrier streams safely.
Carbon Monoxide (CO) & Process Matrices
Removes oxidizers from reactive carbon-containing synthesis gases without poisoning catalytic loops.
Engineering Selection Parameters
To determine the optimal bed volume and ensure performance guarantees, technical evaluation must incorporate the following operating data:
Inlet O₂ Concentration: Normal and peak incoming oxygen levels (ppm or vol%).
Target Outlet O₂ Specification: Maximum allowable downstream residual oxygen.
Complete Gas Composition: Proportions of carrier gases (N₂, Ar, H₂, CO) and co-existing impurities (H₂O, CO₂, hydrocarbons).
Operating Flow Rate: Volumetric or mass flow throughput (Nm³/h or SCFH).
Operating Pressure & Temperature: System pressure and reactor bed temperature profile.
Moisture Content: Feed gas humidity levels, which affect mass transfer efficiency.
Manufacturing, Quality & Physical Properties
Mechanical Crush Strength: Engineered to withstand high bed pressures, preventing bed compaction and pressure drop spikes.
Low Dust Generation: Strict screening processes minimize fines, protecting downstream valves and filters.
Bulk Industrial Supply: Available for initial plant charges, turnaround replacements, and custom industrial orders. Standard export packaging utilizes durable steel drums or industrial jumbo bags.
FAQ
Q: What is the typical service life of the HT-2 catalyst bed?
A: Service life is determined by the cumulative oxygen loading (total oxygen removed over time), operating flow rate, and inlet O₂ concentration. In standard applications with stable trace oxygen levels, the catalyst delivers a prolonged operational lifespan before replacement is required.
Q: How is the required catalyst volume calculated for our reactor?
A: Catalyst volume is calculated using engineering kinetics based on your gas flow rate, inlet O₂ level, target outlet specification, and operating pressure/temperature to ensure adequate contact time and mass transfer efficiency.
Q: Does the catalyst generate moisture during the deoxygenation process?
A: Yes, the chemical reaction between trace oxygen and the active metal oxide site can form trace amounts of water vapor depending on the gas matrix (such as in hydrogen or carbon monoxide streams). The feed moisture and downstream dew point requirements should be reviewed during engineering design.
Q: Can HT-2 be loaded into existing purification vessels or retrofitted?
A: Yes. The catalyst can be supplied in customized particle sizes and physical forms to match the pressure drop and geometrical constraints of existing fixed-bed reactors or dual-tower switching systems.
Q: What safety and handling precautions are required during catalyst loading?
A: The material should be loaded using standard industrial personal protective equipment (PPE) to avoid dust inhalation. Standard loading guidelines and material safety documentation are provided with every commercial shipment.
