摘要：

A relatively rigorous dynamic model is developed for industrial FCC units and is used to investigate the dynamic characteristics of a typical industrial type IV FCC unit. The investigation covers: numerical difficulties associated with the digital dynamic simulation of this system, extreme sensitivity of the dynamics to initial catalyst activity in the reactor, effect of model dimensionality on the reliability of the model predictions, the behaviour of the system with switching control around the middle unstable steady state as well as the behaviour of the closed-loop system with simple feedback proportional control.
