Apparatus and methods for converting hydrocarbon fuels to hydrogen-rich reformate that incorporate a carbon dioxide fixing mechanism into the initial hydrocarbon conversion process. The mechanism utilizes a carbon dioxide fixing material within the reforming catalyst bed to remove carbon dioxide from the reformate product. The removal of carbon dioxide from the product stream shifts the reforming reaction equilibrium toward higher hydrocarbon conversion with only small amounts of carbon oxides produced. Fixed carbon dioxide may be released by heating the catalyst bed to a calcination temperature. Heat for releasing fixed carbon dioxide from the catalyst bed is generated internally within the reactor through oxidation. A non-uniform distribution of catalysts and carbon dioxide fixing material across catalyst bed can be utilized to achieve higher conversion rates of hydrocarbon to hydrogen-rich reformate.
