A method of co-generating propene and aniline in an enclosure that includes a shell, and a first membrane positioned inside the shell to separate a hydrogenation side facing the shell and a dehydrogenation side facing away from the shell. The method includes introducing a dehydrogenation gas including propane into the dehydrogenation side via a dehydrogenation inlet, converting the propane to propene and hydrogen in the presence of a dehydrogenation catalyst and diffusing the hydrogen across the first membrane from the dehydrogenation side to the hydrogenation side. The method further includes introducing a hydrogenation gas including nitrobenzene into the hydrogenation side via a hydrogenation inlet and converting the nitrobenzene and the hydrogen to aniline and water vapors in the presence of a hydrogenation catalyst resulting in exothermic heat. The exothermic heat is transferred across the first membrane from the hydrogenation side to the dehydrogenation side.
