Abstract
The most effective measure of diesel particulate matter(PM) post-processing is the diesel particulate filter(DPF) technology,and the key of DPF lies in its regeneration.In order to reduce the regeneration temperature of DPF,an experimental study was carried out by two steps.The PM from diesel engine was captured by glass fiber filter firstly.Then oxidation of PM was carried by oxidizing gas in a tube furnace.The experimental study on contrast ozone to NO2 oxidation of PM was done.The results indicate that the oxidation reaction between NO2 and PM start combustion at 250 ℃,but ozone and PM start obviously at 155 ℃,the optimal oxidation reaction temperature window is between 200 ℃ and 240 ℃.It gets the higher ozone or NO2 concentration and the faster oxidation reaction.The ozone can oxide PM fast under no any catalyst at low-temperature.
