Abstract

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
