Microgrids are interconnected power generation devices and distributed energy resources that balance energy supply and demand for a locality. Here, this definition is extended to include energy as both power and fuel production from natural gas using small, highly integrated platforms. The extension of this definition beyond traditional boundaries represents a new frontier in energy and fuels research. Critical to fuel platform manufacturing is partial oxidation chemistry, producing syngas with a H2/CO molar ratio of 2 which is ideal for Fischer-Tropsch synthesis. In our laboratory, low cost, fast contact time partial oxidation catalysts are under development. In this investigation, recent progress on a series of Ce and Rh promoted Ba0.75NiAl10O19-δ catalysts is presented. The surface properties of the Ce and Rh promoted catalysts are characterized systematically using H2 chemisorption and the TOF values for CeRh/Ba0.75NiAl10O19-δ are reported for the first time. These activity values are placed in perspective with global kinetic parameters that were elucidated at high-temperature and pressure conditions for this catalyst. Structural features (XRD, XPS, BET, H2-TPR/DSC) of these catalysts in their catalytically active reduced state and their as prepared oxide state are also discussed. H2-TPR/DSC peak locations are shown to correlate with the presence of Ce and Rh promotors.
