Abstract

Processes, systems and equipment can be used to convert carbonaceous fuel to an output gas stream that includes CO as a primary C-containing product. In some embodiments, the processes and systems also can produce H2 in a separate reaction, with the H2 advantageously being capable of being combined with the CO from a partial oxidation process to provide syngas which, in turn, can be used to produce fuels and chemicals. The processes and systems can be tuned so as to not produce significant amounts of CO2 and do not require an air separation unit.
