Effects of temperature and specific input energy on the VOCs conversion were studied. The plasma-catalyst interaction revealed the benefit effect on the VOCs oxidation even at low temperature leading to high CO2 selectivity. The synergistic effect of combining plasma with catalyst in one-stage configuration is observed only for toluene. Keywords: non-thermal plasma, Pd/γ-Al203, synergistic effect, methane, propene, toluene, oxidation 1. Introduction 2. Experimental Volatile organic compounds (VOCs) emitted from The plasma reactor is a cylindrical DBD gives the various industrial and domestic processes are important possibility to combine the catalyst with plasma reactor in sources of air pollution and therefore, become a serious single stage (IPC) or two-stage (PPC) configuration as problem for damaging the human health and the shown in Fig.
