Direct Methane Conversion on Zn Nano-Particles with Methane Jet Generated by Spark Discharge.

Methane direct conversion on nano-catalysts using methane jet generated by spark discharges was carried out. In particular, the effect of the spark discharge on the nano-catalyst was investigated by SEM analysis. In addition, the effect of the supply pressure on the methane conversion was studied. The pressurized mixture of methane and argon were injected into the reactor through the nozzle that was used as a high voltage electrode to generate the spark discharge into the nano-catalysts packed in the reactor. Infra-red thermography was measured to investigate the heating effect on the reaction. The reactor was heated up to 213 °C after the spark discharge at 3 kHz and 9 kV for 30 minutes. The effect of the spark discharge on the methane upgrading and methane decomposition was discussed in this paper.
