Abstract : The reduction of nitrogen oxides (NOx) in a plasma-coupled hydrocarbon selective catalytic reduction (HC-SCR) process was investigated with n-heptane as a reducing agent. Experimental results showed that the plasma/HC-SCR combined process achieved higher NOx conversion efficiency under the same conditions than the HC-SCR-alone process, exhibiting better catalytic activities for the NOxreduction at higher discharge voltages. In the plasma-coupled HC-SCR process, the improvement in theNOxconversion efficiency is interpreted not only by the plasma-induced oxidation of NO to more reactive NO2but also by the decomposition of n-heptane into partially oxidized hydrocarbons such as aldehydes that are more effective reducing agents.
