In this work, a kinetic model was developed for simulation of catalytic reforming process. The feed of catalytic reforming units is heavy naphtha including paraffin, naphthenic compounds and aromatics with 6-9 carbons. Major reactions occurred in the catalytic reactor include dehydrogenation, dehydrocyclization, isomerization, hydrocracking and ring opening. A cylindrical element of catalyst is considered to obtain conservation equations including mass and energy balances. The derived equations are solved by numerical method using MATLAB software to simulate catalytic reforming reactors. Modeling findings involving concentration, temperature and octane number variations were evaluated. Furthermore, simulation results were compared with experimental data and confirmed the accuracy of the developed model.
