Performing endothermic and exothermic chemical reactions in a single unit offers several advantages. It guarantees in general increased thermal efficiency and, for reversible chemical reactions, can lead to increased reactor equilibrium conversion and increased reaction rate due to equilibrium displacement . As a result, energy savings and reduced reactor size are achieved. Some examples demonstrating the effectiveness of this idea are in situ hydrogen combustion in oxidative dehydrogenation coupling propane combustion and endothermic thermal cracking of propane to ethylene and propylene , coupling methane steam reforming with catalytic oxidation of methane in partial oxidation reactors.
