Abstract :
For requirements of nitric oxide (NOx) removal process in diesel engine combustion exhaust gases, a combination process of non-thermal plasma (NTP) chemical applications with physical or chemical adsorption filter is experimentally investigated. The experiments are conducted to evaluate the NOx removal effects of the following processes: an economical conversion process to nitrogen dioxide (NO2) from nitric oxide (NO) molecules with injecting ozone (O3) gas produced by a dielectric barrier type discharge equipment, and a NO2 absorption process passed through an activated carbon filter or a hydrated lime filter for the oxidized by-products in exhaust gases. The experimental results indicate the quantitatively characterized NOx removal processes. The effect of the presented combination process is discussed in the NOx removal efficiency.
