2-way (oxidation) Catalysts

In most gas streams, carbon monoxide (CO) and hydrocarbons (HC) can be removed by combination with oxygen (O₂) using an oxidation catalyst (also known as a 2-way catalyst):

CO + ½ O₂ -> CO₂
[HC] + O₂ -> CO₂ + H₂O

This reaction is suitable for oxygen-rich (“lean”) gas streams, typical of diesel exhaust and many industrial process emissions. Many diesel particulate filter systems incorporate an oxidation catalyst, either as a coating on the filter or as a separate element.

In diesel exhaust applications, oxidation catalysts may also achieve up to 30% reduction of PM emissions.

Typical applications:

• Stationary Source
• Truck and Bus
• Non-road Mobile Machinery
• Cars, Vans and Light Trucks
• 2- and 3-wheel Vehicles
• Small Utility Engines
• Diesel Retrofit
