Reforming hydrocarbon fuels to produce synthesis gas inevitably involves the formation of carbon. This carbon formation leads to deactivation and is especially problematic for reforming diesel-like fuels under dry oxidation conditions. Rh-substituted pyrochlores (Rh-PC) have high thermal stability and resistance to carbon formation under partial oxidation (POX) conditions with diesel fuel. PC surface properties can be modified through various A- and B-site substitutions; therefore, studying carbon formation on different surface sites could provide insight for catalyst optimization by identifying and promoting the most carbon-resistant surfaces. In this work we report a systematic study of the carbon formation on Rh-PC catalysts with various formulas and surface properties by characterizing the carbon formed in the catalyst bed after varying times on stream in the catalytic POX of a surrogate diesel fuel.
