“…When soot was introduced into the system, NOx reduction was suppressed, but N 2 O was still formed (by partial oxidation of NH 3 ) albeit at a higher temperature. Very high concentrations of CO 2 were detected in the presence of soot, when a step-wise oxidation of soot was observed, as described by Davies et al for K-free Ag/CZA [23]. However, the catalyst of Davies et al had the ability to simultaneously reduce NOx and utilize in-situ generated N 2 O to oxidize soot, whilst this catalyst is less effective for NOx reduction in the presence of soot.…”

“…In the presence of soot at 250 • C, a concentration of 70 ppm of CO 2 was measured, compared to the case in the absence of soot, which only produced 30 ppm of CO 2 at 250 • C. This implies that low temperature oxidation (<300 • C) of soot by N 2 O is possible using this catalyst. However, this does not account for the full decrease in the concentration of N 2 O, this is due to some of the N 2 O being stored by soot until higher temperatures [23]. Over this catalyst, a relatively high concentration of CO 2 was observed, particularly at high temperatures, again showing the ability of the catalyst to directly catalyze the oxidation of soot.…”

“…It is a very efficient device for particle filtration [4][5][6]. Resultantly, the combustion-generated nanoparticles, mainly from the internal combustion engine, are removed [7][8][9][10][11], but inevitably, the deposited particles could be a barrier or block for the flow during the filtration, and the unexpected pressure rise may worsen the fuel consumption rate as well as the available torque. Thus, the filter regeneration process for oxidizing and removing deposited soot is needed periodically or continuously [12][13][14][15][16].…”
