Abstract

L'invention concerne un procédé de désalkylation à la vapeur d'eau des hydrocarbures alkylaromatiques, en présence d'un catalyseur. L'invention est caractérisée en ce que la réaction est conduite entre 300 et 600 degrés C, avec un rapport molaire eau/hydrocarbures compris entre 1 et 10, en présence d'un catalyseur constitué d'un support d'alumine et contenant en poids de 0,1 à 2 % d'au moins un métal du groupe VIII de numéro atomique égal ou supérieur à 44, de 0,05 à 2% de rhénium et de 0,01 à 5 % d'au moins un métal alcalin. Le procédé de l'invention s'applique plus particulièrement à la désalkylation en présence d'eau dune coupe issue d'un réformage catalytique ou d'une unité de production d'aromatiques.
