A novel Flexible Fuel Reformer (FFR) that combines mechanical and catalytic innovation to extend conventional reformer performance is being developed by Catacel Corp. in partnership with University of Toledo. The FFR is a low cost, compact, robust, lightweight heat exchange reactor that produces hydrogen by reforming logistic fuels. Sulfur poisoning and coke formation during heavy fuel reforming are two major parameters leading to catalyst deactivation. FFR utilizes Catacel's low-cost high-temperature heat exchanger platform (HEPTM) containing corrugated foil inserts coated with catalyst providing a ‘channel flow profile' to the gas through the reformer. Combustion and reforming reactions occur simultaneously on opposite sides of the exchanger. Cycling the combustion and reforming reactions regenerates the catalyst by burning off carbon and sulfur deposits, resulting in continuous hydrogen production and extended catalyst life. A numerical model coupling these two reactions via a constant heat transfer coefficient, and parallel-flow steady-state operation optimizes the reactor design.
