The reduction of both soot and NOx emissions from diesel vehicles is nowadays mandatory to cope with the next coming emission standards. The potential use of LNT catalyst in the simultaneous removal of soot and NOx has been proposed according to the DPNR concept. The aim of the present study is to analyse the effects of the presence of soot on the behaviour of the PtK/Al2O3 LNT catalysts and in particular to provide new insights on the interaction between soot and the stored NOx during the De-soot and De-NOx activity of the catalyst.

Abstract
The reduction of both soot and NOx emissions from diesel vehicles is nowadays mandatory to cope with the next coming emission standards. The potential use of LNT catalyst in the simultaneous removal of soot and NOx has been proposed according to the DPNR concept. The aim of the present study is to analyse the effects of the presence of soot on the behaviour of the PtK/Al2O3 LNT catalysts and in particular to provide new insights on the interaction between soot and the stored NOx during the De-soot and De-NOx activity of the catalyst.File in questo prodotto:
