Abstract: The thermodynamic properties of the conversion of methane and carbon dioxide were studied.The equilibrium constant of the reaction and the theoretical distributions of products were calculated in order to determine the operating conditions needed to inhibit carbon deposition.The catalytic activity of the conversion of CH4 and CO2 into synthesis gas over Ni/Al2O3 catalyst was examined by using a fixed-bed flow apparatus.It is found that CH4 and CO2 over Ni/Al2O3-3 catalyst has reached the theoretical equilibrium conversions,and the synthesis gas also reached the theoretical yield.The results indicate that Ni/Al2O3-3 catalyst has a high activity,selectivity and stability.

Key words: Catalytic conversion of methane and carbon dioxide, Synthesis gas, Thermodynamics, Carbon deposition
