What is a Metal Particulate Oxidation Catalyst (POC)?
A Metal Particulate Oxidation Catalyst (POC) is a diesel exhaust aftertreatment component that uses a metal honeycomb substrate coated with catalytic materials such as platinum (Pt) and palladium (Pd). It helps reduce harmful exhaust emissions by promoting the oxidation of carbon monoxide (CO), hydrocarbons (HC), and the soluble organic fraction (SOF) contained in diesel particulate matter (PM).
Unlike a Diesel Particulate Filter (DPF), a POC does not physically trap soot. Instead, it lowers particulate emissions through catalytic oxidation while maintaining low exhaust backpressure, making it suitable for selected diesel vehicles, construction equipment, agricultural machinery, generators, and industrial diesel engines.
How Does a Metal POC Work?
As hot diesel exhaust passes through the metal honeycomb catalyst:
1.Carbon monoxide (CO) is oxidized into carbon dioxide (CO₂).
2.Unburned hydrocarbons (HC) are converted into carbon dioxide (CO₂) and water (H₂O).
3.The soluble organic fraction (SOF) in particulate matter is oxidized, reducing PM mass.
1.Some catalyst formulations also promote the conversion of nitric oxide (NO) into nitrogen dioxide (NO₂), which can assist the oxidation of soot under suitable operating conditions.
The metallic substrate provides excellent thermal conductivity, allowing the catalyst to reach its operating temperature quickly.
