ملخص

Methylcyclohexane (MCH) dehydrogenation is an important reforming reaction and is considered as a model naphthene dehydrogenation reaction. An increase in the rate of this reaction with the addition of hydrogen at low pressures has been observed by various researchers in the field. This enhancement in rate is described, in the present study, using the concept of associative adsorption of MCH with hydrogen in Langmuir-Hinshelwood-Hougen-Watson single-site and dual-site surface reaction mechanisms. The various rate equations developed on these bases are tested against the experimental data of Usman over Pt/Al2O3 and the best-fit rate model is presented. An activation energy of 52.0 kJ mol-1 is obtained for the best-fit rate model.
