In this paper, a catalytic reforming kinetic model including 16 lumped components is proposed. The hydrogenation reaction is carried out under the conditions of hydrogen pressure (8 ~ 12) × 10 ~ 5Pa, temperature of 460 ~ 500 ℃ and molar ratio of hydrogen to oil of 10 The kinetic parameters of the model were obtained.The kinetic parameters of the reaction network were estimated by using the optimal step strategy method, the Marquadt method and the regional constraint parameter estimation method to calculate the activation energy and the frequency factor of each reaction.In the model, The fitted values ​​of experimental and calculated values ​​are good, and the model can predict the concentration distribution of each component well.
