“…4 In particular, the application of plasma-catalysis hybrid technology for post-process treatment of pollutants and hydrocarbon reforming has attracted considerable interest because the combination of a plasma with catalysis provides not only high reactivity driven by the plasma but also high selectivity promoted by the catalyst. 5 The combination of a non-thermal plasma with a catalyst has been studied using various catalysts: Ni/SiO 2 or Ni/Al 2 O 3 , [6][7][8][9][10] Rh/Al 2 O 3 , 10 Pt/Al 2 O 3 , 11 Pd/Al 2 O 3 , 11 NiO/Al 2 O 3 , 12 TiO 2 , 13 zeolites, [14][15][16][17] and perovskite LaNiO 3 . 18 Although many studies reported confirmation of the synergistic effects, researchers are only beginning to expound the intricacies of the mechanism.…”

The conversion of methane is measured in a planar-type dielectric barrier discharge reactor using c-Al 2 O 3 (sphere), a-Al 2 O 3 (sphere), and c-Al 2 O 3 (16-20 mesh). Investigations on the surface properties and shape of the three packing materials clearly indicate that methane activation is considerably affected by the material used. Capacitances inside the discharge gap are estimated from charge-voltage plots, and a comparison of the generated and transferred charges for different packing conditions show that the difference in surface properties between c-and a-phase Al 2 O 3 affects the discharge characteristics. Moreover, all packing conditions show different charge characteristics that are related to the electron density. Finally, the packing material's shape affects the local electron temperature, which is strongly related to methane conversion. The combined results indicate that both microscale and macroscale variations in a packing material affect the discharge characteristics, and a packing material should be considered carefully for effective methane activation.

Abstract. The formation of the chemical products produced in an atmospheric glow discharge fed by a N2-CH4 gas mixture has been studied using Fourier Transform InfraRed (FTIR) and Optical Emission Spectrometry (OES). The measurements were carried out in a flowing regime at ambient temperature and pressure with CH4 concentrations ranging from 0.5% to 2%. In the recorded emission spectra the lines of the second positive system CN system and the first negative system of N2 were found to be the most intensive but atomic H α , H β , and C (247 nm) lines were also observed. FTIR-measurements revealed HCN and NH3 to be the major products of the plasma with traces of C2H2. These same molecules have been detected in Titan's atmosphere and the present experiments may provide some novel insights into the chemical and physical mechanisms prevalent in Titan's atmosphere with these smaller species believed to be the precursors of heavier organic species in Titan's atmosphere and on its surface.

“…As it mentioned by Mlotek et al [16] the temperature and reactants concentrations make less effect than energized electron density. So in the non-equilibrium plasmas, the overall reaction rate is controlled by the concentration of energized electrons rather than temperature or reactants concentration.…”

The carbon dioxide reforming of methane to synthesis gas under DC-pulsed plasma was investigated. The effects of specific input energy and feed ratio on the product distribution and also feed conversion was studied. At the input energy of about 11 eV/ molecule per methane and/or carbon dioxide the feed conversion of 38% for CH 4 and 28% for CO 2 and product selectivity of 74% has been attained for H 2 and CO at feed flow rate of 90 ml/min. The energy consumption in this work displays potential to further study and optimization of the process. The importance of the electron impact reactions in the process was discussed. The results show that by prudent tuning of system variables, the process be able to run in the way of synthesis gas, instead of hydrocarbon production.
