The reaction mechanism of methane dry reforming has been investigated using an arc-jet reactor. The effects of input power, CO₂/CH₄ and added O₂ were investigated by product analysis, including CO, H₂, C₂HY and C₃HY as well as CH₄ and CO₂. In the process, input electrical power activated the reactions between CH₄ and CO₂ significantly. The increased feed ratio of the CO₂ to CH₄ in the dry reforming does not affect to the CH₄ conversion, but we could observe increase in CO selectivity together with decreasing H₂ generation. Added oxygen can also increase not only CO selectivity but also CH₄ conversion. However, hydrogen selectivity was decreased significantly due to a increased H₂O formation.

The reaction mechanism of methane dry reforming has been investigated using an arc-jet reactor. The effects of input power, CO₂ /CH₄ and added O₂ were investigated by product analysis, including CO, H₂, C₂HY and C₃HY as well as CH₄ and CO₂. In the process, input electrical power activated the reactions between CH₄ and CO₂ significantly. The increased feed ratio of the CO₂ to CH₄ in the dry reforming doesn't affect to the CH₄ conversion but increase the selectivity of CO with suppressing the reaction of H₂ generation. Added oxygen can also increase not only CO selectivity but also CH₄ conversion, For more understanding these results. the reaction has been compared with thermo-equilibrium calculation.
