Experimental investigation of the oxidation behaviour and thermal kinetics of diesel particulate matter with non-thermal plasma

Explorations on the continuous oxidation kinetics of diesel PM from heavy-duty vehicles using a single ramp rate method

“…The oxidation kinetic calculations using DSC profiles based on the single ramp rate method was seldomly reported to the authors' knowledge. As can be seen from the references [17,18], the details of the oxidation kinetics based on multi-ramp rate method were neglected due to the large temperature intervals. The oxidation kinetics based on the single ramp rate method in references [19,20] were only focused on the high temperature zones.…”

Physicochemical property changes during oxidation process for diesel PM sampled at different tailpipe positions

“…The burn out temperature showed limited differences (Tab. 4) that was smaller than diesel PM sampled at different engine operation conditions [3,7]. The heat-treatment temperature in air for the four samples was around 520 °C (~40% mass loss) that also can be known from TGA profiles of raw PM.…”

“…Soot emitted by diesel engines has brought about huge environmental and health problems [1,2] so that an urgent necessity is needed to decrease diesel PM. Diesel PM is complicated compounds that mainly contain soot, organic compounds, sulphur compounds and metal [3]. Diesel particulate filter (DPF) is considered to be the most successful technology to remove diesel PM while DPF encounters regeneration problem.…”

Oxidation Kinetic Analysis of Diesel Particulate Matter using Single- and Multistage Methods

“…Based on the oxidation profiles, different methods were used to calculate kinetic parameters (activation energy, pre-exponential factors, and reaction rate constant) [7][8][9] . Activation energy of diesel PM sampled at different conditions (engine operation conditions, engine types, fuel types, aftertreatment technologies) was in the range of 80 kJ/mol ~230 kJ/mol [10][11][12][13][14][15][16][17] . The values, calculated using multiple ramp rate oxidation profiles (Kissinger, Akahira and Sunose method), increased generally with mass drop in the oxidation process.…”
