Abstract
La présente invention concerne, dans divers modes de réalisation illustratifs, une composition catalytique appropriée pour une utilisation dans le raffinage d'hydrocarbures. La composition catalytique comprend un noyau ayant un support et un premier matériau catalytique dispersé dans le support, une enveloppe interne permsélective appliquée sur le noyau, et une enveloppe externe appliquée sur l'enveloppe interne permsélective. L'enveloppe externe peut en outre comprendre un deuxième matériau catalytique. La présente invention concerne également, dans divers modes de réalisation, des procédés de préparation de la composition catalytique et leurs utilisations. La présente invention concerne, dans divers modes de réalisation illustratifs, une composition catalytique décrite ici dans laquelle les premier et deuxième matériaux catalytiques comprennent un(e) ou plusieurs métaux ou combinaisons de métaux. La présente invention concerne, dans divers autres modes de réalisation illustratifs, un procédé d'utilisation de la composition catalytique pour l'hydrotraitement d'une alimentation d'hydrocarbure comprenant du sulfure d'hydrogène.
