Patent ID: 7846401

Claim:
A process for controlling the location of an exothermic reaction between two or more reactants in a cyclic reverse-flow reactor system comprising: (a) supplying the first reactant through a first channel means in a first regenerative bed and supplying at least a second reactant through a second channel means in the first regenerative bed, (b) combining said first and second reactants by a gas mixing means situated at an exit of the first regenerative bed and reacting the combined gas to produce a heated reaction product, wherein the cyclic reverse flow reactor system comprises a reaction zone having a volume A, a recuperation zone having a volume B, and a mixer zone having a volume C, whereby volume C is less than about twenty percent of a quantity that is volume A plus volume B plus volume C, (c) passing the heated reaction product through a second regenerative bed thereby transferring heat from the reaction product to the second regenerative bed.
