Performance Evaluation of Dielectric Barrier Discharge Reactor for NOx Reduction Using Non-thermal Plasma Technology

The aim of this paper is to evaluate the influence of effective parameters on the performance of dielectric barrier discharge (DBD) reactor for Nitrogen oxides (NOx) removal by using Non-thermal plasma. The electrode length, the electrode diameter as well as the voltage and frequency of the power generator are studied. To simulate NOx emitted from diesel engine, the combination of pure NOx and N2 cylinders is used. Pulsed plasma treatment of the simulated gas is used due to the advantages of pulse power technology than AC and DC energizations. The results show the capability of the system in reducing NOx from the simulated gas by introducing plasma inside the reactor. Furthermore, increasing the electrode diameter as well as electrode length increases the removal efficiency of NOx. In addition, varying the voltage and frequency of the power generator will affect the performance of DBD reactor.
