Automotive & Stationary Engines

We offer Automotive & Stationary Engines.
The diesel oxidation catalyst is used to oxidize carbon monoxide, hydrocarbons, including the Soluble Organic Fraction (SOF) of diesel particulate matter. As the diesel engine is tuned lean, the exhaust contains upto 16% of Oxygen and under these conditions the reduction of NOx is limited. The CO is oxidised to carbon dioxide and the HC including the SOF are oxidised to carbon dioxide and water. As the SOF is a condensable hydrocarbon and contributes to particulate matter, the DOC also reduces SOF component of particulate matter by 20 – 40% depending on the operating conditions.
Sud Chemie catalysts are designed to provide the highest activity at low temperatures for CO and HC. For use with Sulphur containing fuels, the catalysts are formulated along with an additive to suppress the oxidation of sulphur dioxide to particulate sulphates. They can be offered on both metallic as well as ceramic substrates.
For use in after-treatment systems fitted with downstream Diesel Particulate Filter andor a SCR, Sud Chemie Envicat™ DOC can be custom designed to oxidise controlled quantity of NO to NO2 to facilitate the oxidation of the soot on the DPF and accelerates the deNOx reaction on the SCR at low exhaust temperature to meet the global emission standards.
The Envicat™ DOC have been certified for complying with the legislated emission norms.
