GR-346de is a high-performance deoxygenation catalyst designed specifically for treating industrial gases rich in carbon monoxide (CO). This catalyst exhibits excellent resistance to CO poisoning and efficiently removes oxygen (O₂) at temperatures well below the CO disproportionation reaction temperature (2CO → C + CO₂), avoiding catalyst deactivation and bed plugging caused by carbon deposition.
Utilizing precious metal active components and a specialized support material, this product converts CO and H₂ into CO₂ and H₂O through a catalytic oxidation reaction, achieving deep deoxygenation. Its high activity, excellent stability, and long service life make it particularly suitable for the deoxygenation and purification of CO-rich gases such as syngas, coal gas, acetic acid syngas, and coal-to-ethylene glycol (DMO) syngas, ensuring the safety of downstream catalysts and stable process operation.
