Abstract

The experimental data of six different types of Pt-containing alumina catalysts are used to study the detailed and rigorous kinetics of the methylcyclohexane dehydrogenation reaction. A large number of kinetic rate equations were formulated using the power law kinetics and the Langmuir-Hinshelwood-Hougen-Watson (LHHW) kinetics, which were tested against the experimental data. For each catalyst, the elementary reaction step “the loss of first molecular hydrogen” in the LHHW single-site surface reaction mechanism was observed to be the rate-determining step. The form of the kinetic rate model developed in the study is believed to be applicable to any Pt-loaded alumina catalyst.
