Combined catalytic DOC?NSRC?SCR system for exhaust gas aftertreatment
Original language description
Emission control regulations have been introduced in all industrialized countries in order to reduce the emissions of vehicles powered by internal combustion engines. Economical diesel and advanced gasoline (lean-burn) engines are operated with excess ofair in fuel mixture, with results in high O2 concentrations in exhaust gas and complicated NOx abatement. Combination of NOx storage and reduction catalyst (NSRC) and a catalyst for the selective catalytic reduction of NOx by NH3 (NH3-SCR) offers a potential to significantly increase the efficiency of NSRC-based exhaust gas aftertreatment systems. The Diesel oxidation catalyst (DOC) is often used as the first element in the exhaust aftertreatment line and it is responsible for the oxidation of CO and unburned hydrocarbons. In this paper a complex exhaust gas aftertreatment system including DOC, NSRC and NH3-SCR is studied experimentally. The catalyst samples are placed in series in a nearly isothermal lab mini-reactor.
