It has been taught methods which may be used to transform a monolithic structure into a co-current or countercurrent flow heat exchanger. The monolith is transformed by cutting or grinding the uppermost section of diving walls from rows of channels contained in the honeycomb. The top end of the newly formed groove is then sealed with suitable cement. The depth of the sealant is such that an opening still exists in the side wall of the structure. A manifold is attached to this inlet. A similar exercise is performed at the opposing end to produce an outlet section. Hot gas is passed through the inlet whilst cold coolant is passed through the open end. Efficient heat transfer occurs between the two streams. However, the possibility of using such an arrangement for coupling endothermic and exothermic catalytic processes on opposing sides of each dividing wall is not taught. It has been taught a method to efficiently transfer energy through a divider by contacting a catalyst to the wall and performing an exothermic reaction there. The energy is conducted through the wall and used to heat a gas stream on the opposing side of the wall. An apparatus is described where multiple layers are formed with alternating hot and cold channels to produce a gas heater. However, the method does not discuss the possibility of utilizing this concept for thermally coupling endothermic and exothermic reactions within a monolith reactor.
