  • Description of Research
    • The advancement in liquid fuel production from biological sources will result in oxygenated fuel compositions. While oxygen is beneficial for combustion purposes, its presence within the chemical makeup of the fuel is detrimental to the fuel’s energy density. In understanding how oxygenated fuel may be reformed to remove the oxygen functional groups, we have been exploring ethanol reforming as a test case. Recently, initial results show for the first time that the oxidation state of catalytic Rh nanoparticles changes dynamically under reaction conditions with ethanol and that the extent of Rh oxidation appears to control catalyst activity and the rate of deactivation. Catalyst deactivation is one of the major challenges faced in fuel reforming and there exists a need not only to determine the primary causes, but model them in order to take preventative measures.
