KH-MO Active Hydrogen Recombiner

The KH-MO Active Hydrogen Recombiner is a high-efficiency hydrogen treatment system based on rare-earth metal oxide catalytic technology. Featuring an innovative dual-tower structure and circulation pump system, the device continuously conveys hydrogen-containing gas into the reaction towers for hydrogen removal. Through real-time monitoring by intelligent sensors and an automatic switching mechanism, the system ensures continuous hydrogen elimination and unattended operation. It is widely used in energy storage stations, fuel cell systems, industrial hydrogen purification, and other applications.

Product Features

Unique Metal-Oxide Hydrogen Removal Mechanism

The system uses rare-earth metal oxides, including cerium oxide and MnO₂, as catalysts. Through active sites on the catalyst surface, metal ions adsorb hydrogen molecules and dissociate them into hydrogen atoms, which then react with lattice oxygen atoms to form water vapor. This mechanism provides a sufficient internal oxygen source for the reaction, fundamentally ensuring highly efficient and stable hydrogen removal. Rapid reaction can occur without the participation of external oxygen.

Rare-Earth Catalysis for Efficient Hydrogen Removal

The involvement of rare-earth metals effectively reduces the activation energy required for the hydrogen reaction, allowing it to proceed rapidly under moderate conditions. Compared with other metal-oxide catalysts, the system delivers a higher hydrogen removal rate, enabling fast and efficient elimination of hydrogen from gas mixtures and significantly improving treatment efficiency.

Dual-Tower Redundancy for Continuous and Stable Operation

The system adopts a dual-tower redundant operating mechanism, with one tower in service and the other on standby. Hydrogen sensors on the carrier-gas side and at the reaction tower outlet continuously monitor operating conditions. When the catalyst activity in the active tower falls to the preset lower limit, the system automatically switches to the standby tower, while the previous operating tower enters an automatic catalyst reduction and regeneration cycle. Alternating operation between the two towers ensures stable 24-hour continuous operation and minimizes downtime.

Intelligent Temperature Control for Wide-Ranging Operating Conditions

Each reaction tower is equipped with an independent catalyst preheating unit and reaction-gas cooling unit. The preheating system is specifically designed for cold regions to keep the catalyst at its optimal reaction temperature, while the cooling system effectively regulates high-temperature reaction gases. This enables the equipment to adapt to a wide range of temperature conditions and significantly expands its scope of application.

Intelligent Operation and Precise Control

The equipment integrates an intelligent control system that accurately identifies the hydrogen removal status and catalyst activity based on sensor data. According to actual operating conditions, the system can automatically adjust its operating mode, including initiating preheating, switching towers, and triggering regeneration. This enables fully automatic operation with minimal manual intervention.
