Patent

CA 2380503

A catalyst for use in a hydrocarbon fuel processor for converting, or reforming, a hydrocarbon fuel such as diesel into a simple fuel, most especially hydrogen, comprises a rare earth metal (M) cobalt oxide (McoO3) having the perovskite structure. In one composition the catalyst comprises a solid solution having the perovskite structure of the rare earth metal cobalt oxide, preferably lanthanum cobalt oxide LaCoO3, and an alkaline earth metal cobalt oxide, preferably strontium cobalt oxide SrCoO3. To further enhance the catalytic activity the catalyst can additionally include a noble metal oxide such as platinum or ruthenium.

L'invention concerne un catalyseur à utiliser dans un dispositif de traitement de carburant hydrocarboné, pour la conversion ou le reformage d'un carburant hydrocarboné, tel que le Diesel, en carburant simple, particulièrement en hydrogène. Ledit catalyseur comprend un oxyde de cobalt (McoO¿3?) de métal rare, présentant une structure pérovskite. Dans une composition, le catalyseur comprend une solution solide présentant la structure pérovskite de l'oxyde de cobalt de métal rare, de préférence de l'oxyde de cobalt de lanthane LaCoCO¿3?, de préférence de l'oxyde de cobalt de strontium SrCoO¿3?. De manière que son activité catalytique soit encore augmentée, le catalyseur peut également comprendre un métal noble ou un oxyde de métal noble, tel que le platine ou le ruthénium.
