Reaction coupling between propane dehydrogenation and nitrobenzene hydrogenation over a commercial Pt/Al2O3 catalyst is presented. The effects of coupling, use of the catalyst, and reaction temperature were studied using a fixed-bed reactor. The coupling of the two reactions drastically increased propane and nitrobenzene conversions even without the use of the catalyst. The use of Pt/Al2O3 further increased the conversions and the selectivity towards propylene and nitrobenzene hydrogenation products. Higher reaction temperatures favored the selectivity towards pyrolysis products. Reaction pathways are sketched to explain our experimental findings. [Display omitted] •Non-catalytic reaction coupling drastically increased propane and nitrobenzene conversions.•The use of Pt/Al2O3 further increased both conversions.•Product distributions were altered by the presence of the catalyst and the change of reaction temperatures.•Reaction pathways of this catalytic reaction coupling system are sketched.
