Süd-Chemie Inc. is producing and supplying an autothermal reforming (ATR) catalyst that was developed by Argonne National Laboratory (ANL) for reforming hydrocarbon fuels to generate H2 for automotive fuel cell systems. The catalyst is derived from solid oxide fuel cell technology, where a transition metal is supported on an oxide-ion-conducting substrate, such as ceria or zirconia, that is doped with an un-reducible oxide, such as gadolinium or samarium, to improve its oxide ion conductivity and to increase the number of surface oxygen ion vacancies. The catalyst has been shown to produce an H2-rich gas (reformate) from a wide variety of hydrocarbon fuels, including methane, natural gas, and commercial-grade gasolines and diesels with high selectivity. Platinum was the transition metal used in the first generation of the ANL catalyst.
