A method and apparatus for the production of hydrogen-rich gas are provided. The method and apparatus prevent over-reduction of iron oxide-based shift catalyst by introducing an oxidative stream along with a carbon monoxide containing gaseous feed stream from a catalytic steam reformer to the catalyst bed region and thereby limits structural deterioration of the catalyst. Various sources may provide the oxidative stream including a shift catalyst bed region and a selective oxidation catalyst region.

Divulgation d'une méthode et d'un appareil pour produire un gaz riche en hydrogène. La méthode et l'appareil préviennent la sur-réduction d'un catalyseur de conversion à base d'oxyde de fer par introduction d'un flux oxydatif avec un flux d'alimentation gazeux contenant de l'oxyde de carbone provenant d'un dispositif de reformage catalytique à la vapeur, et son acheminement vers la région du lit catalytique, ce qui limite la détérioration structurelle du catalyseur. Le flux oxydatif peut provenir de diverses sources, notamment d'une région du lit catalytique de conversion et d'une région du catalyseur d'oxydation sélective.
