Abstract: Fluid Catalytic Cracking Unit (FCCU) is one of the most important processes in a refinery, which converts molecular-weight gas oils into lighter hydrocarbon products. The mechanistic dynamic model was developed for the FCCU reactor-regenerator system, which was composed of the five-lump dynamic mechanism model and the two-stage regenerator model. The Marquardt algorithm was adopted to evaluate model parameters, and fourth order Runge-Kutta method was used for the equations. Axial distribution of lump components in riser and key steady-state variable values were obtained. The results show that the model can describe the products rate with satisfied accuracy and can be used directly for the advanced control and process optimization.
