A kind of single-electrode tip discharge plasma reaction systems at atmospheric pressure was built for non-thermodynamic conversion of benzene, one of tar compounds in the CO₂ plasma assisted gasification process. The gas analyzer was used to study the syngas production, and emission spectrum was used to diagnose the plasma. The results showed that the main gaseous product of benzene conversion in this reaction system is CO, and the H element is directly oxidized to H₂O. The energy density plays a dominant role in the conversion of benzene. At the same energy density, the decrease of benzene concentration can also increase the conversion ratio of benzene, However, the conversion of benzene can not be improved by changing the gas velocity and increasing the reaction time. In addition, based on spectral analysis, the non-thermal conversion of benzene can be triggered by O-radicals generated by direct dissociation of CO₂.
