摘　　要：研究了甲烷二氧化碳转化反应的热力学特性,计算了反应平衡常数及平衡组成,分析和确定了抑制积碳的生成条件,采用固定床流动和脉冲反应装置研究了Ni/Al_2O_3催化剂对甲烷二氧化碳转化的催化性能。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.
