Paper Title:
CO2 Reforming of CH4 via Cold Plasma Jet Combined with Catalyst
  Abstract

CO2 Reforming of CH4 to syngas by Ni/γ-Al2O3 catalyst combined with cold plasma jet was investigated. The higher selectivity of H2 and CO, and higher energy efficiency were obtained compared with other kinds of plasmas. Under the experimental conditions of flow rate at CH4=200 NL/h, CO2=300 NL/h, N2=500 NL/h, the input power at 0.77 kW, for the operation of plasma only, the conversions of CH4 and CO2 were 45.68% and 34.03%, the selectivity of CO and H2 were 85.41% and 78.11%, the energy efficiency was 2.94 mmol/kJ, respectively. Keeping the same conditions, the catalysts of 12%Ni/γ-Al2O3 were put following the plasma discharge zone. Without accessorial calefaction to catalysts, the conversions of CH4 and CO2 were increased by 14.38% and 6.32%, the yield of H2 and CO increased by 18.76% and 11.38%, the energy efficiency reached at 3.67 mmol/kJ, respectively. It was strongly verified that the cooperation action of clod plasma jet with catalysts at reforming of CH4/CO2.
