Conclusion

  1. 1.

    The activity, selectivity, and mechanism of conversions of C6-hydrocarbons over alumina-platinum catalysts with substantial acidic function (Pt/Al2O3 and Pt-Re/Al2O3-F) are dependent on the partial pressure of hydrogen in the gas phase.

  2. 2.

    At relatively low hydrogen concentrations, C5- and C6-dehydrocyclization and skeletal isomerization of alkanes, and the hydrogenolysis of methylcyclopentane, are promoted, owing to its direct involvement in the reactions and to the removal of firmly adsorbed hydrocarbon forms from the surface. At high partial pressures of hydrogen, the competitive nature of the adsorption of the hydrocarbon and hydrogen results in the suppession of these reactions.

  3. 3.

    Skeletal isomerization of alkanes proceeds preferentially by the C6-cyclic mechanism at high hydrogen concentrations, and by the bifunctional mechanism at low concentrations.
