Dehydrogenation methylcyclohexane

As shown in Table 13.1, toluene is a candidate compound to form the naphthalene oil. To utilize the reaction pair of methylcyclohexane dehydrogenation/toluene hydrogenation as an additive component, it is, thus, necessary to generate hydrogen efficiently from methylcyclohexane under mild reaction conditions.

Corma el al. (126) found that PtNaY was an active but rather unstable catalyst for methylcyclohexane dehydrogenation to toluene. These workers studied both the dehydrogenation and the catalyst decay kinetics. It was concluded that the reaction occurs via a series of consecutive partial dehydrogenation steps, the first of which was rate determining. Further, catalyst deactivation was caused by coke deposition from partially unsaturated precursor molecules.

A number of different models that fulfilled the six assumptions above were fitted to the experimental data. Equation (2) describes the model that gave the most satisfying fit. The same equations have been used by Wolf and Petersen [1] to describe the reversible deactivation behavior during methylcyclohexane dehydrogenation on Pt/y-AhOs.

More recent work by Wolf and Petersen (37,38) has investigated the influence of the order of the main reaction on single pellet diffusion reactor behavior, using the same model deactivation mechanisms studied before. Experimental application to a reaction with complicated kinetics (and complicated deactivation behavior) was reported for methylcyclohexane dehydrogenation.
