Patent ID: 6969506

Claim:
A method of conducting an endothermic reaction in an integrated combustion reaction, comprising: passing an exothermically reacting composition into at least one exothermic reaction chamber, wherein the exothermic reaction chamber comprises at least one exothermic reaction chamber wall that is adjacent at least one endothermic reaction chamber, wherein the exothermic reaction chamber comprises an exothermic reaction catalyst in contact with at least the at least one exothermic reaction chamber wall that is adjacent at least one endothermic reaction chamber, wherein the exothermic reaction catalyst has an exposed surface within the exothermic reaction chamber, and wherein the exposed surface of the exothermic reaction catalyst and a second surface within the exothermic reaction chamber define an open channel within the exothermic reaction chamber, wherein the gap has a thickness, in a direction perpendicular to net flow where the direction of net flow is the direction that gas would travel through the exothermic reaction chamber during operation, of 2 mm or less; wherein the exothermic reaction composition reacts in the exothermic reaction chamber and generates heat; and passing an endothermic reaction mixture into the at least one endothermic reaction chamber; and wherein the method has a volumetric heat flux of at least 1 W/cc.
