Minstrong carbon monoxide catalyst can convert carbon monoxide into carbon dioxide at normal temperature, avoiding equipment and personnel from being damaged by carbon monoxide. The catalyst adopts chemical synthesis method to manufacture active ingredients, and accurately controls each process parameter of the synthesis reaction. Aluminum oxide is used as a binder, and the active ingredient content is as high as 85%. The powder does not contain binders, and the active ingredient is as high as 99%. The catalyst does not contain activated carbon, can adapt to different working conditions, does not burn, has no volatility, which is safe to use, and does not cause secondary pollution. Applications: 1.Purify carbon monoxide in refuge chambers, airtight compartments and respirators to avoid carbon monoxide poisoning; 2.Purify carbon monoxide in air separation system and compressed gas, remove carbon monoxide at low temperature; 3.Remove carbon monoxide from process gas; 4.Remove the carbon monoxide in the flue gas, and realize the discharge of carbon monoxide up to the standard.
