“…However, as mentioned in Section 3.3, temperature inside DBD reactor was about 250 • C at peak voltage of 9000 V. Ozone is unstable and is suppressed at this temperature [2,32]. Therefore, oxidation of NH 4 NO 2 and NH 4 NO 3 by O 3 can be neglected.…”

“…The chemistry related to the oxidation of NO has been discussed in detail in the previous publications. (20,21) Basically, ozone formed by O and O 2 plays an important role in the oxidation of NO to NO 2 , but the increase in temperature decreases the formation of ozone. In addition, the rate of the reaction between NO and O as well as that between NO and OH causing NO oxidation decreases with the increase in temperature.…”

“…In addition, the rate of the reaction between NO and O as well as that between NO and OH causing NO oxidation decreases with the increase in temperature. (21) That is why the NO oxidation was lower at higher temperature. Meanwhile, a part of NO 2 formed by the NO oxidation can be converted into HNO 3 by OH radical.…”

Dielectric barrier discharge (DBD) and catalysis hybrid process was used to remove nitrogen oxides and particulate matters from diesel engine exhaust. The DBD reactor converts a part of NO into NO 2 , and then the exhaust gas containing the mixture of NO and NO 2 enters the catalytic reactor where both NO and NO 2 are reduced to N 2 . The effect of energy density (power input divided by gas flow rate) and reaction temperature on the removal of nitrogen oxides was investigated with a stationary diesel engine. The hybrid process was able to remove about 80% of the initial nitrogen oxides at an energy density of 25 J/L and 150 • C. The removal of particulate matters did not largely depend on the electrode structure, but it was a strong function of the energy density. On the basis of 80% removal efficiency, the energy yield for nitrogen oxides was 40 eV/molecule while that for particulate matters was 83 kJ/mg. The present study suggests that this kind of hybrid process can be applied to simultaneous removal of nitrogen oxides and particulate matters from diesel engine exhausts.
