According to the established eight-carbon reforming reaction network and kinetic model, the kinetic experiments of pressure microreactor and H / C molar ratio of 10, pressure of 8 ~ 12kPa and temperature of 460 ~ 500 ℃ were carried out. Using the 90 sets of experimental data obtained by the method of region constraint and experiment, the kinetic constants and pressure exponents of each reaction in the reaction network are estimated, and the frequency and activation energy of each reaction are calculated. The calculated values of the model and each component Of the experimental values can be a good fit, and can better predict the model of the various components of the product distribution.
