【摘要】 本文针对催化裂化工业装置的提升管反应器以三集总催化裂化反应动力学模型为基础,利用工业装置的现场数据对模型中的参数进行了拟合。提出了将三集总催化裂化反应动力学微分方程组转化为卡尔曼滤波状态方程的处理方法。对拟合得到的参数进行了卡尔曼滤波参数估计。滤波后得到的模型可以对提升管进行模拟。模型中的参数随数据的积累能够不断得到校正。开发的计算机模拟软件可以预测提升管的单程转化率和产品产率分布。更多还原

【Abstract】 Based on three lumping kinetic model of catalytic cracking, the parameters in the model are estimated with actual operation data of a commercial catalytic cracking riser. A method is proposed for converting the differential equations of three lumping kinetic model into the state equations of Kalman filter. Kalman filter estimation method is carried out to estimate the parameters obtained above. The model modified with Kalman filter may be able to simulate the riser well. And the parameters in the model can be modified as more data are collected. The computer simulation programmes are developed to simulate the one pass conversion and yield distribution of the riser.更多还原
