In this paper a simplified mathematical model (isothermal) to describe the cracking ofa molecule (1,3,5 triisopropylbenzene model) over a Y zeolite exchanged with rare earth (REHY) is presented. In determining the involved kinetic constants experimental data in two different temperatures (348 and 396°C) have been considered. Results obtained demonstrate good concordance between simulations and experimental data. By adopting the Arrhenius equation and with the kinetic constants adjusted for the two different temperatures, the apparent activation energies for the different rate constants of the consecutive model were possible to estimate.
