催化裂化装置的动态模拟和操作分析是优化操作和先进控制的基础。在强调催化裂化动态机理模型的优点后,对二级裂化反应转化率经验模型和集总反应动力学模型两大类动力学模型、再生过程中烧碳、烧氢动力学模型、床层再生器流化模型、快速床再生器流化模型和反应器 再生器动态数学模型进行了详细的评述,并指出运用动态机理模型对装置操作进行分析,特别是装置稳定性分析可以为催化裂化装置的设计、操作和控制提供依据
Dynamic simulation and operational analysis of catalytic cracking units are the basis for optimized operation and advanced control. After emphasizing the merits of the dynamic mechanism model of FCC, two models of kinetic model of two-stage cracking conversion reaction and two kinds of kinetic models of lumped reaction kinetics are described. The kinetics models of carbon burning and hydrogen burning during regeneration, bed regenerator Fluidized model, fast bed regenerator fluidized model and reactor regenerator dynamic mathematical model were reviewed in detail, and pointed out that the use of dynamic mechanism model to analyze the operation of the device, in particular, the device stability analysis for the catalytic cracking unit design , Provide the basis for operation and control
