Detailed reaction kinetics for the dehydrogenation of methylcyclohexane over Pt catalyst / Muhammad Usman in Industrial & engineering chemistry research, Vol. 51 N° 1 (Janvier 2012)

Experiments were conducted in a fixed-bed reactor for a wide range of operating conditions including reactions without hydrogen in the feed. Kinetic model equations were developed, and the experimental data were analyzed according to the power-law, Langmuir–Hinshelwood–Hougen–Watson (LHHW), and Horiuti–Polanyi kinetic mechanisms. The rate of loss of the first hydrogen molecule in the LHHW single-site surface reaction mechanism was found to be the rate-controlling step. Experiments with 1-methylcyclohexene confirmed that the rate-controlling step does not lie after the loss of the first hydrogen molecule.
