Abstract
NOx removal method by non-thermal discharge has some problems like contamination of reactor by soot and low energy efficiency to reduce NOx. The energy efficiency of NO removal is known as around 20g/kWh, but it decreases at higher NO oxidation rate. This degradation comes from the reverse reaction of NO2 to NO by 0 radicals. In this paper, NO removal by ozone injection is reported. This method is free from both contamination by soot and the degradation of NO removal efficiency at higher NO removal rate. The experiments were carried out using 2.4 KVA diesel engine exhaust gases. The energy efficiency obtained by ozone injection method is 25g/kWh, which is fairly good in comparison with direct discharge method. It was also confirmed that there is no degradation of efficiency up to more than 90% removal. These results are discussed by calculations of chemical reactions.
