Dehydrogenation of Methylcyclohexane on Ruthenium-Silica Catalysts

NIPPON KAGAKU KAISHI, 1974
Dehydrogenation of methylcyclohe'xane on Ru-SiO2 catalysts was studied. Main products were methylcyclohexenes (three'isomers contained), benzene and toluene. ln the steady state (Fig. 1), the initial reaction rate [Eq. (2)], was examined in the reaction scheme shown in Eq (1).

Successive Operation of Dehydrogenation-Hydrogenolysis for Methylcyclohexane

Journal of The Japan Petroleum Institute, 1966
The combination reaction comprising successive operations of dehydrogenation and hydrogenolysis for methylcyclohexane have been studied using a conventional flow apparatus. Dehydrogenation was carried out over a commercial chromia-alumina catalyst at temperatures ranging from 300 to 640°C under an atmospheric pressure, while hydrogenolysis ranging from

Dehydrogenation of Methylcyclohexane: Parametric Sensitivity of the Power Law Kinetics [PDF]

ISRN Chemical Engineering, 2013
For heterogeneous catalytic reactions, the empirical power law model is a valuable tool that explains variation in the kinetic behavior with changes in operating conditions, and therefore aids in the development of an appropriate and robust kinetic model.
