The catalytic dehydrogenation of methylcyclohexane over monometallic catalysts for on-board hydrogen storage, production, and utilization

A methylcyclohexane-toluene-hydrogen system employs methylcyclohexane as a recyclable organic hydride for the on-vehicle production, storage, and utilization of hydrogen gas. The success of the methylcyclohexane-toluene- hydrogen system lies in the success of the dehydrogenation reaction of methylcyclohexane. A highly active, selective, and stable catalyst is required to carry out the dehydrogenation reaction. A range of commercial and in-house development catalysts are studied for the dehydrogenation of methylcyclohexane. The catalytic data is compared with the study in the literature. Alumina-supported Ni metal catalyst and Pt/-zeolite show poor activity and selectivity towards toluene. Pt/Al ₂O ₃ in-house development catalysts show reliable results of activity, selectivity, and stability.
