By-Products Formation in the Dehydrogenation of Methylcyclohexane

Petroleum Science and Technology, 2011
The selectivity of the by-products' formation for the dehydrogenation of methylcyclohexane (MCH) is studied under varying conditions of temperature, pressure, and feed composition. Benzene, cyclohexane, and ring-closed products (dimethylcyclopentanes and ethylcyclopentane) were found as the major by-products.

Ni/Al2O3 catalysts and their activity in dehydrogenation of methylcyclohexane for hydrogen production

Catalysis Today, 2008
Abstract Previous results on different catalysts revealed that methylcyclohexane underwent selective dehydrogenation to form toluene and hydrogen. This reaction system is a useful prototype model for similar systems in the chemical process and petroleum refining industries, such as hydrotreating for aromatics reduction, desulfurization ...

A Review of Catalysts for Methylcyclohexane Dehydrogenation

Topics in Catalysis, 2021
Methylcyclohexane (MCH) is regarded as an excellent hydrogen energy carrier due to its reasonable theoretical hydrogen storage content (6.22 wt%) and physicochemical performance. Methylcyclohexane-toluene-hydrogen (MTH) cycle realizes the recycling of materials and energy, and has a good prospect of industrial application.

Long-Term Deactivation of Supported Pt Catalysts in the Dehydrogenation of Methylcyclohexane to Toluene

Industrial & Engineering Chemistry Research, 2010
The kinetics of methylcyclohexane (MCH) dehydrogenation over supported Pt catalysts was successfully described by a non-Langmuirian/noncompetitive Horiuti-Polanyi model (Ind. Eng. Chem. Res., in press). The daily reversible and irreversible deactivation, associated with activity tests, was satisfactorily included in the dehydrogenation model.

Detailed Reaction Kinetics for the Dehydrogenation of Methylcyclohexane over Pt Catalyst

Industrial & Engineering Chemistry Research, 2011
Detailed reaction kinetics of the dehydrogenation of methylcyclohexane were studied over an in-house-prepared 1.0 wt % Pt/γ-Al 2O 3 catalyst. Experiments were conducted in a fixed-bed reactor for a wide range of operating conditions including reactions without hydrogen in the feed.

Kinetic Model of the Dehydrogenation of Methylcyclohexane over Monometallic and Bimetallic Pt Catalysts

Industrial & Engineering Chemistry Research, 2010
Various kinetic models were developed for methylcyclohexane (MCH) dehydrogenation over supported Pt catalysts. The best fitting mechanistic model is of the non-Langmuirian/noncompetitive Horiuti-Polanyi type. In this model, the Horiuti-Polanyi aromatic hydrogenation mechanism, which assumes an atomic hydrogen addition to aromatics on the catalyst ...

Enhanced methylcyclohexane dehydrogenation to toluene over Ir/USY catalyst

Catalysis Today, 2016
Selective dehydrogenation of methylcyclohexane (MCH) to toluene over Ir, Pt, Pd and Ni supported on ultrastable USY zeolite was studied in the context of the hydrogen storage using MCH-toluene-hydrogen cycle. The MCH dehydrogenation was carried out in a fixed-bed flow reactor at 250 °C, total hydrogen pressure of 30 bar and WHSV of 92.4 h−1.
