In this work we compare the results of detailed models of state-of-the-art catalyst evaluation procedures for the Fluid Catalytic Cracking (FCC) process with experimental data for different catalyst testing reactors (MAT, SCT-MAT, ACE and DCR) used in catalyst evaluation. Key properties of the models include that they can be practically implemented in everyday catalyst evaluation procedures and that they use the same reaction kinetics network and catalyst deactivation function(s) for different catalyst testing reactors. Two different models have been developed, an empirical one based exclusively on a lumping kinetic reaction-network and a more realistic one that includes hydrodynamic characteristics of the units in the calculations. In particular, the later incorporates the calculation of the molar expansion of the gases inside the reactor, modified to phase flow model. The figure shows modeling results against experimental data using both models developed (using a six-lump reaction-network scheme) for a MAT reactor.
