Fluid catalytic cracking(FCC) is an important process in converting heavy oil into light distillates. The modelling of FCC riser reactors is essential in the development of novel FCC processes and new equipment,as well as the steady operation and optimization of FCC units. This paper reviewed the coupled flow-reaction models for FCC risers between flow models and reaction models. The evolvements of the coupled flow-reaction models were also reviewed. The applications of the coupled CFD flow-reaction models were presented and the decoupling methods in solving the coupled models were addressed. Meanwhile,the disadvantages of the coupled CFD flow-reaction models were analyzed and the requirement of online sampling technologies for industrial FCC riser reactors was pointed out. Finally,the studies on the coupled flow-reaction models were summarized. This review would provide reference for investigations in novel modeling approaches for FCC riser reactors and for validations of the coupled models.
