4. Conclusion
In this paper, CO2 reforming of CH4 to syngas by binode thermal plasma is studied in three operation modes. The
optimal results of the specific energy of 193 kJ/mol and the energy conversion efficiency of 66% are achieved under the
conditions of CH4/CO2 of 4/6, input power at 14.4 kW, 500 g Ni/Al2O3 catalyst, Ar of 1.9 m3/h from inlet I, N2 of 1 m3/h and feed gases of 1.5 m3/h from inlet II, and feed gases of 3.5 m3/h from inlet III, which benefits from the three different reaction courses:
1) The cracking reaction of the feed gases introduced from inlet II by the impact of energetic particles in plasma
discharge region;
2) The thermochemical reaction of the feed gases introduced from inlet III in the high temperature plasma jet out of the
discharge region;
3) The catalytic reaction of the unconverted feed gases from 1) and 2) on the commercial Z107 Ni/Al2O3 catalysts.
