The kinetics of methylcyclohexane (MCH) dehydrogenation over supported Pt catalysts was successfully described by a non-Langmuirian/noncompetitive Horiuti−Polanyi model (Ind. Eng. Chem. Res., in press). daily reversible and irreversible deactivation, associated with activity tests, satisfactorily included the model. objective this work is to incorporate long-term deactivation catalysts, life or kinetic This has been achieved assuming that sum two exponential decay processes, one rapid completed few days, while other slow half-life weeks months.
