Abstract
L'invention concerne la régénération de catalyseurs. Selon l'invention, on réduit l'oxyde de platine d'un catalyseur à l'aide d'hydrogène au cours de l'activation ou de la régénération de ce dernier en maintenant la température du catalyseur en dessous de 371 degrés C, puis on met le catalyseur en contact avec une atmosphère non oxydante à n'importe quel moment avant la réaction complète de l'oxyde de platine sur l'hydrogène pour former du platine élémentaire, si bien que l'oxyde de platine ne réagit pas sur les substances hydrocarbonées présentes dans l'atmosphère non oxydante. L'avantage du procédé réside dans le fait que l'on peut utiliser de l'hydrogène de provenance non électrolytique.
