Abstract

L'invention concerne un procédé de régénération d'un reformeur, qui est alimenté, lors d'un fonctionnement continu du reformeur, par un mélange de combustible (12, 14) et d'agent d'oxydation (16, 18, 20) avec un indice d'air moyen ?<SUB>1</SUB>, l'indice d'air étant modifié en vue de la régénération du reformeur. Selon l'invention, la régénération a lieu pendant une phase d'interruption du reformeur. À cet effet, le reformeur est mis en fonctionnement pendant plusieurs intervalles successifs de temps avec un indice d'air augmenté ?<SUB>2</SUB>>?<SUB>1</SUB> par rapport au fonctionnement du reformeur. Selon l'invention, la régénération peut également avoir lieu pendant une phase de début du reformeur. À cet effet, le reformeur est mis en fonctionnement en continu avec un indice d'air augmenté ?<SUB>2</SUB>>?<SUB>1 </SUB>par rapport au fonctionnement du reformeur, jusqu'à ce qu'un seuil critique de température soit atteint. L'invention concerne d'autre part un système comportant un reformeur et un dispositif de commande permettant la mise en oeuvre dudit procédé.
