NOVELTY - A fuel processing assembly (10) has a reforming region for receiving feed stream(s) (16) containing carbon-containing feedstock (18) and producing a mixed stream containing hydrogen, and a heating assembly (60) having fuel chamber(s) and heating and ignition source(s). The fuel chamber receives fuel stream(s) (F) at a temperature (T1). One fuel stream (F) contains liquid, combustible, and carbon-containing fuel. Heating and ignition source raises the temperature of a portion of the carbon-containing fuel to a second temperature (T2), and the carbon-containing fuel is ignited.    USE - Used for producing hydrogen used in the manufacture of metals, edible fats and oils, and semiconductors and microelectronics, and used as a fuel for a fuel cell.    ADVANTAGE - The fuel processing assembly efficiently and simply enables the production of hydrogen.    DETAILED DESCRIPTION - The fuel processing assembly has a reforming region for receiving feed stream(s) containing a carbon-containing feedstock and producing a mixed gas stream containing hydrogen gas as main component, and a heating assembly provided in thermal communication with the reforming region. The heating assembly has fuel chamber(s) and heating and ignition source(s). The fuel chamber receives fuel stream(s) (F) at a temperature (T1). The fuel stream (F) contains liquid, combustible, and carbon-containing fuel having an ignition temperature greater than temperature (T1). The heating and ignition source carries out heating of a portion of the fuel chamber to raise the temperature of the portion of carbon-containing fuel to a second temperature (T2), and the carbon-containing fuel is ignited.    An INDEPENDENT CLAIM is included for operation of a fuel processing assembly.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of the fuel processing assembly.
