摘　　要：研究了甲醇水蒸气转化制氢反应在Cr -Zn催化剂MOR -67上的本征动力学。试验表明 ,CO和CO2 同时生成 ,可用水蒸气转化反应和甲醇分解反应作为独立反应平行进行的模型表示。利用非线性最小二乘法确定模型参数 ,并进行F统计检验。The intrinsic kinetics of methanol-steam reforming over ZnO-Cr 2O 3 catalyst has been investigated. Experimental data show that CO 2 and CO are produced simultaneously.A parallel reaction model is employed, taking SRM and DE as independent reactions.Based on this conclusion,the author established the intrinsic kinetic equations for methanol steam reforming reactions.The parameters were estimated for the rate model using a non-linear regression program which computes weighted least squares of the defined objects function.
