Abstract: n-Butane was used as the model compound for aromatization, and the distribution of products was investigated under different conditions. According to the aromatization reaction mechanism and product distribution characteristics, the kinetic parameters of n-butane aromatization were obtained by solving a set of nine-episode chemical kinetic model equation with eight virtual reaction paths, and the prediction results of the nine-lumped kinetic model were verified by the experimental data. The results showed that the maximum absolute error between the predicted value of the product distribution model and the measured value of the test was less than 5.0%, which indicated that the model was accurate and reliable, and could reflect the reaction law of aromatization of light hydrocarbons, it could be used to simulate and optimize the actual production process.
