CO Oxidation Catalysts

Carbon Monoxide Oxidation Catalyst

Honeycomb-supported catalysts that promote the oxidation of carbon monoxide to CO₂ at elevated temperature, applied to sintering machines, waste incinerators, industrial boilers and furnaces.

Overview

The CO oxidation catalyst uses a honeycomb ceramic (or activated alumina) substrate with a washcoat and precious-metal / oxide active system. It accelerates the reaction 2CO + O₂ → 2CO₂ so CO is removed before the gas is discharged. Active components can involve Pt, Pd, Rh, Zr and Ce; the formulation is selected from the actual gas conditions.

FAQ

Frequently Asked Questions

What CO conversion has been achieved in field tests?

Documented field tests include a sintering machine where CO dropped from 1,499 ppm to 18 ppm (2022-08-23) and a medical waste incinerator where CO fell from 11,224.2 mg/Nm³ to 16.2 mg/Nm³ (2023-03-20). See our case studies for details.

Does the catalyst tolerate SO₂ and water vapor?

The formulation is designed for SO₂ and water resistance, but the acceptable limits depend on concentration and temperature. Provide your gas composition for evaluation.

What substrates are available?

Cordierite honeycomb and activated alumina. The choice depends on temperature, thermal shock and mechanical requirements.
