For heterogeneous catalytic reactions, the empirical power lawmodel is a valuable tool that explains variation in the kinetic behavior\r\nwith changes in operating conditions, and therefore aids in the development of an appropriate and robust kinetic model. In the\r\npresentwork, experiments are performed on 1.0 wt% Pt/Al2O3 catalyst over awide range of experimental conditions and parametric\r\nsensitivity of the power law model to the kinetics of the dehydrogenation of methylcyclohexane is studied. Power law parameters\r\nsuch as order of the reaction, activation energy, and kinetic rate constants are found dependent upon the operating conditions.\r\nWith H2 in the feed, both apparent order of the reaction and apparent activation energy generally increase with an increase in\r\npressure. The results suggest a kinetic model, which involves nonlinear dependence of rate on the partial pressure of hydrogen and\r\nadsorption kinetics of toluene or some intermediate.
