A single stage process for desulfurization and ring opening of a sulphur containing hydrocarbon feedstock comprising: contacting said feedstock with hydrogen and a catalyst at a pressure of less than 100 bars wherein said catalyst comprises (I) a combination of molecular sieves consisting of at least one zeolite which has a faujasite structure and at least one fibrous zeolite which comprises essentially non-crossing one-dimensional channels and (II) a composition comprising at least one metal selected from group VIB of the periodic table and at least one metal from group VIII.

La présente invention concerne un procédé en une étape de désulfuration et d'ouverture de cycle d'une charge d'alimentation à base d'hydrocarbure qui contient du soufre. Ce procédé consiste à mettre en contact la charge d'alimentation avec de l'hydrogène et un catalyseur, à une pression inférieure à 100 bars, ledit catalyseur comprenant (I) une combinaison de tamis moléculaires constitués d'au moins un zéolithe qui présente une structure de faujasite et d'au moins un zéolithe fibreux qui comprend des canaux à une dimension sensiblement parallèles et (II) une composition comprenant au moins un métal choisi dans le groupe VIB du tableau périodique et au moins un métal du groupe VIII.
