The invention comprises, in one form thereof, a chemical processing method to thermally contact an endothermic and an exothermic reaction without mixing the two streams, utilizing a thermally coupled monolith reactor (TCMR). A ceramic or metal monolith is modified to produce a structure containing at least two sets of discrete flow paths and which are separated by a number of common walls. Manifolds are arranged such that one reaction mixture flows through one set of channels and a different reaction mixture flows through the second.
