摘要：A new kinetic model involving 44 lumped pseudocomponents and 70 reactions for catalytic reforming was developed to satisfy real-time optimization of the commercial counter-current continuous catalyst-regenerative reforming units. The reaction kinetic model was constructed with the equation oriented method, using the orthogonal collocation method to transform the differential equations of the kinetic model into algebraic equations with variables. The sequential quadratic programming method is used to solve the equation oriented model in this study. The validation results showed that the good agreement of material compositions and catalyst coke content at the exit of the fourth reactor, as well as the temperature and pressure at the exit of each reactor, was obtained between simulated values and industrial values. Moreover, the reactor kinetic model is also used to predict the influence of process parameters which is consistent with the trend in actual industrial production. The model makes it possible to find optimal conditions in real-time optimization.
