A carbon monoxide removal method capable of removing carbon monoxide stably for long period when a fuel reforming system is operated, comprising the step of adding oxidizer to a reaction gas including hydrogen and carbon monoxide to react on a carbon monoxide removal catalyst so as to remove the carbon monoxide under the conditions that (1) the temperature of the reaction gas is held at 100 ~C or below, (2) the temperature of a catalyst layer is held at 130 to 180 ~C, and (3) a gas flow passage is formed of a non-ferrous material or (4) an iron particle arresting means is installed on the upstream side of a catalyst part.
L'invention concerne un procédé d'évacuation du monoxyde de carbone capable d'évacuer le monoxyde de carbone de manière stable pendant une longue période lorsque le système de reformage de combustible fonctionne. Ledit procédé consiste à ajouter un oxydant à un gaz de réaction, comprenant de l'hydrogène et du monoxyde de carbone, qui réagit sur un catalyseur d'évacuation du monoxyde de carbone, le monoxyde de carbone étant évacué dans des conditions telles (1) que la température du gaz de réaction est maintenue à 100 °C au maximum, (2) que la température de la couche de catalyseur est maintenue entre 130 °C et 180 °C, et (3) qu'un passage d'écoulement gazeux est formé d'un matériau non ferreux ou (4) qu'un dispositif d'arrêt de particules de fer est installé en amont d'une partie catalyseur.
