Partial oxidation provides a low energy pathway to convert natural gas into synthesis gas with a H2/CO molar ratio of 2 and minimal downstream conditioning which is ideal for small-scale Fischer-Tropsch. Under development in our laboratory are fast contact-time partial oxidation catalysts that operate at high-pressures and temperatures. In this investigation, recent progress on promoted Ni-hexaaluminate catalysts is discussed for application in small-scale distributed fuel manufacturing. When integrated with power production a highly innovative small-scale microgrid focused manufacturing platform results which can be used to service population centers. Fundamental TT and TOF values are reported for one of the Ni-hexaaluminate catalysts as are global kinetic parameters that were elucidated at high-pressure. XANES analysis of this catalyst shows the leading-edge of the catalyst serves to catalyze CH4 combustion until all molecular oxygen is consumed which is then followed downstream by steam and dry reforming reactions. The catalysts are structurally characterized in their as prepared and reduced states by XRD, XPS, BET and H2-TPR/DSC to provide insight into the nature of the active sites.
