本文研究了在Cu-Zn-Al和γ-Al_2O_3构成的复合催化剂上CO+H_2合成甲醇、二甲醚的本征动力学行为。在此复杂体系中,同时存在着CO+H_2合成甲醇、甲醇脱水生成二甲醚和水气变换三个反应。文中给出了表达这三个反应的动力学方程式,并通过数据拟合求出了动力学参数。模型的计算值与实验值相符较好。
In this paper, the intrinsic kinetic behavior of CO + H_2 synthesis of methanol and dimethyl ether over Cu-Zn-Al and γ-Al_2O_3 composite catalysts was studied. In this complex system, there are three reactions of CO + H_2 synthesis of methanol, methanol dehydration to dimethyl ether and water vapor shift. The kinetic equations for expressing these three reactions are given and the kinetic parameters are obtained by fitting the data. The calculated value of the model is in good agreement with the experimental value.
