摘要
根据提升管反应器的动态机理,考虑反应对压力的影响,结合物料平衡、能量平衡方程,建立了馏分油5集总催化裂化反应动力学模型。使用Nelder-Mead最优化法进行了参数的拟合,并用MATLAB对模型进行了仿真。通过对工业装置数据的计算比较表明,该模型能较好的预测催化裂化产品产率,可用于实际催化裂化过程。
Baseing on the equations of mass, energy, composition balance, the five lumping dynamic mechanism models of the Fluidized Catalytic Cracking Unit （FCCU） reactor were developed. Nelder- Mead minimization algorithm was adopted to model parameters and used MATLAB to describe model. The results of the simulation showed that this simple model was capable of sensible predictions of the dynamic responses of each lupmings.
