Nonthermal Plasma Regeneration of Diesel Particulate Filter 2003-01-1182

A regeneration of DPF with collected PM was investigated using the low temperature atmospheric pressure nonthermal plasma. The method is to use the NO2 and radicals induced by the plasma reactor to burn carbon soots deposited on DPF. First, the performances on the conversion of NO to NO2 of the three types of DPF plasma reactors were evaluated on various conditions. Next, a regeneration experiment was carried out using a barrier type pulsed corona plasma reactor. As a result, the regeneration of DPF using the plasma was confirmed when the gas temperature was 250°C.
