详细介绍了多相催化加氢数学模型回归的计算方法。对无副反应存在下数学模型可以处理成为线性模型进行简化,从而求得参数。但该法直接使用的dCdt值,是使用作图镜面法获得,会引入误差。本文着重介绍使用计算机对反应数据进行dCdt值和参数同时回归的实现方法、原理、流程,以及应用Matlab语言回归时所需的命令和求解方法。同时,该方法也可应用于多组份多副反应动力学的回归。
The calculation method of the regression of the mathematical model of heterogeneous catalytic hydrogenation is introduced in detail. For the absence of side effects, the mathematical model can be treated as a linear model to simplify, thus obtaining the parameters. However, the value of dCdt used directly by this method is obtained by using the specular method, which introduces errors. This article focuses on the realization of the method, principle, flow, and the command and solution method required when using Matlab language to return the dCdt values and parameters simultaneously. At the same time, this method can also be applied to the regression of multi-component and multi-side reaction kinetics.
