Hydrogen Storage in the Form of Methylcyclohexane

The use of compounds, such as toluene, that can store hydrogen with a specific volume of 46 kgH2/m3 in the form of methylcyclohexane, has been already shown to be potentially feasible for both mobile and stationary applications. Thus, produced hydrogen by the dehydrogenation of methylcyclohexane to toluene could be a very attractive option to be adopted for these applications. In this study, dehydrogenation of methylcyclohexane reaction for hydrogen production was investigated. The catalytic experiments were made in a tubular pyrex glass fixed bed reactor. The experiments were performed between 380°C and 440°C under the total pressure of about 1 atm with a Pt/Re/Al2O3 (sulfided) catalyst (UOP) (UK). Power law rate models were tested for the experimental data. r = k.Pm MCH was found as an appropriate model for the experimental data of this study.
