摘要: The present invention relates generally to the field of exhaust treatment systems for purifying exhaust gas discharged from a lean burn engine. The exhaust treatment system comprises a Diesel Oxidation Catalyst (DOC), a Catalyzed Soot Filter (CSF), a reductant injector, an AEI zeolite based Selective Catalyzed Reduction (SCR) catalyst and an Ammonia Oxidation Catalyst (AMOX) downstream to the AEI zeolite based SCR catalyst.

摘要: The present disclosure relates to a catalyst for NOx removal. In some embodiments, the catalyst comprises a support comprising at least one selected from the group consisting of TiO2, Al2O3, SiO2, ZrO2, CeO2, zeolite, TiO2 and WO3, and combinations thereof, and catalytically active components supported on the support. The catalytically active components comprise vanadium, antimony and at least one further component selected from the group consisting of silicon, aluminum and zirconium.
