Abstract (en)
[origin: WO2010016631A1] Disclosed is an SCR catalyst composition having improved NOx conversion and a device for post- treat ing diesel engine exhaust gas using the same. The SCR catalyst composition can effectively convert NOx generated from an engine into harmless components. The device, which improves the NOx conversion, includes an SCR catalyst module disposed downstream of a diesel engine and having an injector, an oxidation catalyst module disposed downstream of the SCR catalyst module, and a catalyst soot filter module, all of which are successively arranged in series.
