Larger engines, in trucks and buses, are almost exclusively diesel powered. In order to meet required legislation across a wide range of engine types and sizes, dedicated emission control systems are being developed. Compliance to the upcoming regulations for both mobile and stationary diesel engines is being met by use of numerous strategies, with catalyst technologies playing a major role. Diesel Oxidation Catalysts (DOC), Catalysed particulate filters (CDPF), lean NOx traps (LNT) and Selective Catalytic Reduction (SCR) catalysts are all being developed to meet legislative targets.
MELChemicals develop and manufacture a wide range of materials for use in catalysis; our technology allows us to customise powder properties to suit a wide range of catalytic applications. For use as catalyst supports in DOC and especially CDPF, systems that have excellent sulphur tolerance and thermal stability are available. The particle size distribution of the powders allows them to be washcoated with PGM (Pt or Pt/Pd systems).
