根据工业反应器的实例数据，对邻二甲苯的催化氧化反应系统进行物料衡算与热量衡算。以Ｃａｌｄｅｒｂａｎｋ、Ｌｙｕｂａｒｓｋｉｉ和Ｆｒｏｍｅｎｔ动力学模型为基础做了回归分析，按拟均相一维模型法建立新的动力学模型，用修正系数α概括传递过程阻力对反应速度常数的影响。修正系数。表示反应温度及邻二甲苯转化率的多项式方程。用四阶尤格－库塔法做模型计算得到的反应器最终转化率与产物分布、床层轴向的温度分布、反应系统的物料与热量平衡等主要指标均与实例值相符合。
According to the data of the industrial reactor, the material balance and heat balance of the system of catalytic oxidation of o-xylene are calculated. Based on the Calderbank, Lyubarskii and Froment kinetic models, a regression model was established and a new kinetic model was established based on the quasi-homogeneous one-dimensional model. The influence of process drag on the reaction rate constants was generalized with the correction coefficient α. Correction factor. A polynomial equation representing the reaction temperature and o-xylene conversion. The final reactor conversion and product distribution, the axial temperature distribution in the reactor and the material and heat balance of the reaction system calculated by the fourth-order Yogurt-Kutta method are consistent with the example values.
