New carbon-supported Pt catalysts were characterized and evaluated in the direct nonoxidativedehydrogenation of n-butane to butenes. After a comparison with catalysts supportedon oxidic materials, Pt catalysts supported on carbon nanotubes and Vulcan carbon showed thebest activity and selectivity to olefins, and a low deactivation throughout the reaction time. Thisfact is attributed to the chemical properties of such carbonaceous materials, which lead to a goodmetal-support interaction and metallic dispersion, excellent accessibility to reactants and to theformation of a suitable metallic phase, thus favoring the dehydrogenation reaction and inhibitingcollateral ones. Pt catalysts supported on Vulcan carbon and carbon nanotubes become verypromising candidates for the large-scale development of catalysts applied in the direct lightparaffin dehydrogenation process.
