Claim:
1. A process for the production of power using a combination of a partial oxidation (POX) system and a power production system (PPS), the process comprising: combining a solid or liquid carbonaceous fuel and oxygen in a POX reactor under conditions sufficient to partially oxidize the solid or liquid carbonaceous fuel and form a POX stream at a first temperature comprising a fuel gas; cooling the POX stream to a second temperature that is less than the first temperature and thus form a cooled POX stream; removing at least a portion of any solids present in the POX stream; separating at least a portion of any water present in the POX stream; compressing the POX stream to a pressure suitable for combustion in a PPS combustor; combusting the fuel gas in the POX stream in the PPS combustor to form a PPS combustion product stream; expanding the PPS combustion product stream across a PPS turbine to generate power and form an expanded PPS combustion product stream; passing the expanded PPS combustion product stream through a PPS recuperator heat exchanger and thereby withdrawing heat from the PPS combustion product stream and forming a cooled PPS combustion product stream; removing at least a portion of one or more impurities from the cooled PPS combustion product stream to form a recycle CO pressurizing the recycle CO
