Abstract
The effects of precursors and NH4OH treatment of Rh catalysts supported on CeO2-promoted Al2O3 for steam reforming of liquid hydrocarbon fuel (jet fuel) for micro solid oxide fuel cell applications were studied. Impurity chlorine in the RhCl/CeO2-Al2O3 catalyst was detrimental to the steam reforming of higher hydrocarbons at lower temperature. This might be explained by a blocked and thus decreased accessible active surface sites as a consequence of the chemical interaction of the halogen with the catalyst surface. Removal of residual Cl- from RhCl/CeO2-Al2O3 by NH4OH treatment improved the metal dispersion and showed higher, and stable, activity for pre-reforming of model jet fuels. The pre-reformates from the current pre-reformer contained mainly CH4, CO, H2, in which CH4 could be further converted to H2 and CO by subsequent main-reforming, or directly used for a micro solid oxide fuel cell. This is an abstract of a paper presented at the 227th ACS National Meeting (Anaheim, CA 3/28/2004-4/1/2004).
