摘要

开发了一种一维均相反应器模型,用于模拟一氧化碳和亚硝酸乙酯催化耦合反应器中固定床反应器的动态行为。反应器建模是通过使用 Simulink 模拟的综合数值模型进行的。在模拟催化偶联反应时,考虑到了主反应和副反应,采用了幂律动力学模型。计算了每个反应的反应热与亚硝酸乙酯的反应摩尔数。当模拟模型达到稳定状态时,预测结果与已建立的中试装置固定床反应器收集的实际数据一致。模拟了年产 78,000 吨草酸二乙酯的假设工业规模生产的启动动态行为。系统在 14-16 分钟内达到稳态,空间速度为 1400 h-1。

Modeling and simulation of the startup of the coupling reactor for Industrial-Scale production of Diethyl oxalate

A one-dimensional homogeneous reactor model was developed to simulate the dynamic behavior of a fixed-bed reactor for a catalytic coupling reactor of carbon monoxide and ethyl nitrite to diethyl oxalate. Reactor modeling was performed using a comprehensive numerical model that was simulated using Simulink. The power law kinetic model was applied for simulating the catalytic coupling reaction considering the main and side reactions. The heat of reaction was calculated with respect to the reacted moles of ethyl nitrite for each reaction. When the simulated model reached a steady state, the predicted results were in agreement with the actual data that was collected from an already established pilot plant fixed bed reactor. The startup dynamic behavior of hypothetical industrial-scale production of diethyl oxalate at 78,000 tons per year was simulated. The system reached steady-state within 14–16 min at a space velocity of 1400 h−1.
