The partial oxidation of methane to synthesis gas over catalysts consisting of Rh supported on hexaaluminates (BaAl12O19, CaAl12O19 and SrAl12O19) was investigated at atmospheric pressure and high reactant dilution in order to compare their performances within the kinetic-controlling regime. Comparison with the results obtained over a commercial Rh/-Al2O3 system indicates that hexaaluminate catalysts are active and selective in this reaction. Despite of the higher surface area of the support, hexaaluminate-supported catalysts were found less stable, active and selective than an -Al2O3-supported catalyst.
