Claim 0:
1. A method for hydrogen production from a carbonaceous fuel with capture of carbon dioxide derived from the carbonaceous fuel, the method comprising:
reacting a first portion of the carbonaceous fuel from a carbonaceous fuel stream in a first reactor with oxygen under conditions effective to produce a first reaction stream comprising hydrogen and carbon monoxide;
reacting a second portion of the carbonaceous fuel from the carbonaceous fuel stream in a second reactor with steam under conditions effective to produce a second reaction stream comprising hydrogen and carbon monoxide, wherein the reacting in the second reactor is endothermic, and wherein exhaust heat from the first reactor is transferred to the second reactor to provide at least a portion of the heating needed to carry out the reacting in the second reactor;
combining the first reaction stream comprising hydrogen and carbon monoxide with the second reaction stream comprising hydrogen and carbon monoxide to provide a total reaction stream comprising hydrogen and carbon monoxide;
processing the total reaction stream comprising hydrogen and carbon monoxide through a unit or units effective to provide a stream of substantially pure hydrogen and a waste stream comprising at least carbon dioxide;
providing the waste stream comprising the at least carbon dioxide to a combustor in a power production cycle configured for capture of the carbon dioxide in combination with power production, the combustor being configured for combusting a third portion of the carbonaceous fuel from the carbonaceous fuel stream with oxygen under conditions effective to produce a combustor exhaust stream comprising at least carbon dioxide; and
processing the combustor exhaust stream comprising the at least carbon dioxide so that the carbon dioxide from the combustor exhaust stream is provided as a compressed, substantially pure stream.
