The Sinfelt’s [Sinfelt, J.H., Hurwitz, H., and Shulman, R.A., J. Phys. Chem. 64, 1559-1562, 1960] kinetic model for the dehydrogenation of methylcyclohexane (MCH) is a popular two-step kinetic model in which methylcyclohexane is adsorbed and converted to toluene on the surface in the first step and the toluene formed is desorbed from the surface in the following step. The kinetic model is adopted by other researchers in the field and fitted the experimental data in their work. Experiments are performed over 1.0 wt% Pt/Al2O3 and the Sinfelt’s kinetic model is analyzed both statistically and kinetically for the experimental data.
