High activity sulfur tolerant steam reforming catalysts are described comprising iridium, palladium or platinum supported on lanthanum stabilized alumina or magnesium promoted lanthanum stabilized alumina. The catalysts have improved activity over conventionally used catalysts in the presence of sulfur containing hydrocarbon fuels, particularly in a steam reforming environment. The catalysts have utility in autothermal, tubular, cyclic and adiabatic steam reforming processes.

Steam reforming catalyst

Steam reforming utilizing sulfur tolerant catalyst

High activity steam reforming catalysts are described particularly adapted for use in autothermal reforming processes. A rhodium catalyst on a calcium oxide impregnated alumina substrate allow the autothermal reforming process to take place with substantially no carbon plugging at oxygen to carbon ratios below what had been considered critical for avoiding carbon plugging of the catalyst in the past.
