DOC - Diesel Oxidation Catalyst
The Diesel Oxidation Catalyst (DOC) coating applied for metallic and ceramic substrates is a hydrothermally durable composition which shows also high Sulphur resistance. The PGM loading levels and Pt:Pd ratios are designed to the specific needs of the application. For future HDD on-road applications, the NO2/NOx ratio is designed to be high to ensure the passive regeneration of the soot and the optimum DeNOx performance on the SCR catalyst.
