A process for the catalytic generation of hydrogen by the self-starting, self- sustaining combination of partial oxidation and steam reforming of dimethyl ether comprises contacting a mixture of the dimethyl ether, an oxygen- containing gas and steam with a precious metal catalyst which is selective for the partial oxidation reaction. Suitable catalysts include platinum or rhodium supported on zirconia or a mixture of ceria and zirconia.
La présente invention concerne un procédé destiné à la production catalytique d'hydrogène par la combinaison, auto-amorçable et auto-entretenue, d'oxydation partielle et de vaporeformage de diméthyléther. Ce procédé comprend la mise en contact d'un mélange de diméthyléther, d'un gaz contenant de l'oxygène et de vapeur d'eau en présence d'un catalyseur de métal précieux sélectif pour la réaction d'oxydation partielle. Du platine ou du rhodium sur un support de zircone ou d'un mélange de zircone et d'oxyde de cérium sont des catalyseurs appropriés.
