Applications
CO Removal from Industrial Exhaust
Catalytic oxidation converts carbon monoxide to CO₂ — the practical route where combustion control alone cannot meet emission limits.
How catalytic CO oxidation works
Carbon monoxide is oxidized to CO₂ over a catalyst — 2CO + O₂ → 2CO₂ — at temperatures far below the thermal route. Precious-metal catalysts on honeycomb ceramic (cordierite) or alumina substrates operate across roughly 150–600°C, covering the exhaust windows of sintering machines, waste incinerators, furnaces and process vents. The catalyst converts CO that survives imperfect combustion; it is not a substitute for combustion control, but the final step that meets the emission limit.

Selection checklist
| CO inlet concentration | the catalyst converts what combustion leaves behind; state the inlet and target outlet. |
| Exhaust temperature | catalytic oxidation is windowed; position the reactor where the exhaust temperature matches the catalyst. |
| O₂ content | the reaction needs oxygen; verify the excess-air level at the reactor position. |
| Co-pollutants | dust, SO₂ and alkali metals degrade catalyst activity over time; they set the maintenance interval. |
| Flow fluctuation | incinerator streams cycle; the catalyst must tolerate thermal cycling (see field test records). |
