Abstract

L'invention concerne un procédé de régénération de catalyseur à base d'une zéolithe. Elle se caractérise en ce qu'on opère une partie du traitement régénératif en atmosphère humide. Elle s'applique à la régénération de catalyseurs utilisés dans les réactions de dismutation et de transalkylation d'hydrocarbures aromatiques.
