Abstract: Systems and methods are provided for improving control of the temperature profile in a cyclic flow reactor, such as a reverse flow reactor, during operation. The improved temperature control is achieved in part based on inclusion of regions having reduced or minimized catalyst density with increased volumetric heat capacity within the reaction zone of the reactor. This improved control over the temperature profile is achieved while reducing or minimizing any loss of reaction capacity due to lowering the amount of catalyst in the reaction zone.
