摘要
以丁烯氧化脱氢反应为例说明工业反应过程开发放大方法。根据初步试验注意到绝热反应器的多态行为在实验室与工业规模反应器之间有显著差别，应用数学模型和计算机模拟分析了形成多态的各因素，解释了工业反应器不出现多态的原因，计算机模拟和实验结果揭示了进口气体温度和气体线速是敏感因素。作者注意到两种不同直径反应器器壁热反馈不同和气速的影响，最后工业反应器被成功地开发放大。
This paper aims at illustrating a case of scaling-up an industrial process-the oxidativedehydrogenation of butene. According to the preliminary experiments, attention has beenpaid to the considerable difference between laboratory and commercial scale reactors. Variousfactors which make multiplicity prossible are studied using mathelnatical modeling and com-puter simulation. It has been explained why multiplicity disappears in a commercial scale reac-tor. Both computer simulation and experimental results have revealed that the inlet gas tem-perature and gas velocity are sensitive factors.The authors have noticed various effects of theheat feedback through reactor wall in two reactors of different diameters and the effect ofgas velocity. Finally,a commercial scale reactor is successfully developed.
