  • Description of Research:
    • Autothermal Reforming (ATR) of JP8 Fuel:
      Much of the recent work on Fuel Processors is focused on the employment of surrogate fuels, biofuels, gasoline and diesel and to a lesser extent devoted to JP8 fuel. JP8 is a mixture of alkanes, cycloalkanes and arenes in the C8 -C16 range, containing ~102 ppm of fuel bound sulfur. Since JP8 is the fuel selected by the Department of Defense (DoD) and North Atlantic Treaty Organization (NATO) to be the only battlefield fuel for all units, a better understanding of its properties and behavior is paramount. Apart from being used for producing a suitable feed to Fuel Cells, Fuel Processors can be utilized for bio-oil upgrading, as well for combustion enhancement in internal combustion engines.
      For this investigation a novel catalytic-fins reactor was built in partnership with ATK/GASL and BASF. This investigation has the objective to shed light into catalyst ignition in the presence of sulfur as well as the impact and fate of sulfur species at steady state.
    • The Interaction Between Mass Transfer Processes and Chemical Kinetics in Selective Catalytic Reactors:
      My dissertation work is focused on understanding the mechanism responsible for the performance in the high temperature regime of the preferential oxidation of CO in the presence of hydrogen (PROX). This is investigated experimentally by the employment of reactors exhibiting different flow geometries (short contact time screens and monoliths) and by TGS/DSC analysis. The theoretical impact of various parameters is investigated with a 2-phase, one-dimensional model with heat and mass transfer resistances for the PROX reactor.
