【摘要】 本文在常压下用直流管式等温积分反应器研究了C301型铜基催化剂上CO-H₂-CH₃OH 系统中甲醇分解反应本征动力学。在不同温度和组成的情况下测定了甲醇分解的速率。用非线性最小二乘法对幂函数型甲醇分解反应本征动力学模型进行了参数估值,得到甲醇分解的动力学方程为:R_m=-（dN_m）/（dW）m=0.3202×10¹⁰exp（-（26610）/（R_gT））p_H2^-0.25p_CO^-0.25p_m^0.5mol/（g·hr）由甲醇分解反应的活化能求得合成反应的活化能为14990 cal/mol。更多还原

【Abstract】 In this paper the intrinsic kinetics of methanol decomposition in theCO-H₂-CH₃OH system under atmospheric pressure over C-301 cupricbased catalyst has been investigated in an isothermal tubular-flow inte-gral reactor.The rates of methanol decomposition have been measuredunder different temperatures and compositions.By means of nonlinearleast square method,the parameter estimation of the intrinsic kineticmodel of the power type for the methanol decomposition has been per-formed.The kinetic equation of methanol decomposing into carbonmonoxide and hydrogen isR_m=-（dN_m）/dW=0.3202×10¹⁰ exp（（26610）/（R_gT））p_H2^-0.25p_CO^-0.25P_m^0.5From the activation energy of the methanol decomposition,it has beendeduced that the activation energy of the synthesis reaction is 14,990cal/mol.更多还原
