Modelling of a combined NOx storage and NH3-SCR catalytic system for Diesel exhaust gas aftertreatment
Original language description
A combined Diesel exhaust gas aftertreatment system is studied, consisting of the NOx storage and reduction catalyst (NSRC, called also lean NOx trap, LNT) and the catalyst for selective catalytic reduction of NOx by NH3 (NH3-SCR). Most of the time the system is operated under prevailing fuel-lean conditions, enabling economical running of the engine. During this phase the NOx emissions are being adsorbed in the NSRC. However, short fuel enrichments need to be applied periodically for the NSRC regeneration (reduction of the stored NOx). Ammonia produced in the NSRC as a by-product of the NOx reduction under controlled fuel-rich conditions is then adsorbed in the NH3-SCR reactor located downstream. The adsorbed NH3 is consequently utilised in selectiveNOx reduction during the next fuel-lean period. The NSRC+SCR configuration thus eliminates the need for an external NH3 source (e.g., periodically re-filled urea solution tank) that is necessary in the case of the stand-alone SCR. Develop
