Soot Incineration of Diesel Particulate Filter Using Honeycomb Nonthermal Plasma 2003-01-1886

A direct incineration or regeneration of DPF with collected PM was investigated using atmospheric pressure nonthermal plasma which was induced inside DPF. The method is to use the NO2 and radicals induced by the plasma to burn carbon soots deposited on DPF. Conversion of NO to NO2 was evaluated using three types of DPF honeycomb plasma reactors. Then, the regeneration experiment was carried out using a DPF honeycomb plasma reactor. As a result, it was confirmed that the pressure drop decreased when the plasma was turned on and the regeneration of DPF was confirmed at the low temperature of 200°C.
