Abstract

Pour réactiver un catalyseur à métal du groupe du platine selon l'invention, on traite le catalyseur dont l'activité catalytique est diminuée avec au moins une substance choisie parmi les substances minérales alcalines et les substances réductrices dans un milieu aqueux. Ce procédé s'applique en particulier à la régénération des catalyseurs utilisés pour les réactions catalytiques des hydrocarbures renfermant éventuellement un atome d'oxygène.
