Abstract
By using a self-designed non-thermal plasma (NTP) injection system, an experimental study of the regeneration of DPF was conducted at different temperatures, where oxygen as the gas source. The results revealed that PM can be decomposed to generate CO and CO2 by these active substances O3, O which was generated through the discharge reaction of NTP reactor. With the increasing of test temperature, the mass of C1 (C in CO) shows a overall downward trend while the mass of C2 (C in CO2) and C12 (C1 and C2) increase firstly and then decrease. When the test temperature is 80°C, the backpressure of DPF decreases fastest and the regenerative effect is remarkable. DPF can be regenerated by NTP technology without any catalyst at a lower temperature. Compared with the traditional regeneration method, the NTP technology has its superiority.
