Routine laboratory testing data of e-cat and its corresponding fresh catalyst deactivated under different conditions were used together with an optimization algorithm, in order to determine the simulated mixture that better mimics the overall e-cat performance. It was demonstrated that the simulated performance result for the mixture presented a much closer approach to the e-cat performance than any of each sample separately. This procedure could be applied to choose the optimum catalyst for a given commercial FCC unit, provided that samples of the e-cat and corresponding fresh catalyst are available. In the present paper all the deactivated samples were obtained by hydrothermal deactivation due to its low time consumption, but other more sophisticated deactivation procedures might as well be used. The simple methodology proposed in this paper could be applied to any laboratory testing unit or even pilot plant unit, allowing the establishment of specific deactivation protocol for any particular FCC unit.
