Abstract:
1. A hydrocarbon fuel gas autothermal reformer assembly comprising: a) a monolithic open cell foam core catalyst bed, said catalyst bed including an inlet end and an outlet end, an inlet portion of said catalyst bed being provided with a catalyst which is operable to combust a portion of the fuel gas so as to raise the temperature of said catalyst bed while minimizing carbon deposition in catalyzed cells of said foam core, said foam core catalyst bed including a high temperature-compatable metal support selected from the group consisting of stainless steel, nickel alloys and iron-aluminum alloys, and said catalyst bed further including a noble metal and calcium oxide; b) a fuel gas inlet passage, said fuel gas inlet passage being disposed in heat exchange relationship with an outlet processed fuel gas passage from said catalyst bed whereby heat will be transferred to said fuel gas inlet passage from the processed gas stream; c) an air inlet passage, said air inlet passage being disposed in heat exchange relationship with processed gas stream whereby heat from the processed gas stream will be transferred to said air inlet passage; and d) a fuel gas reforming catalyst deposited in said foam core catalyst bed.
