Patent

CA 2689990

The invention relates to a two-step hydroprocessing method for a load from a renewable source that comprises: a) a first so-called soft pre-hydrogenation step carried out in the presence of a first metal catalyst containing at least one hydro-dehydrogenation active phase including at least one metal of the group VIII and/or at least one metal of the group VIB and an amorphous mineral substrate; and b) a second so-called processing step carried out in the presence of a second sulphured catalyst containing at least one hydro-dehydrogenation active phase including at least one non-noble metal of the group VIII and/or at least one metal of the group VIB and an amorphous mineral substrate.

L'invention décrit un procédé d'hydrotraitement en deux étapes d'une charge issue d'une source renouvelable comprenant : a) une première étape, dite étape de pré hydrogénation douce, opérant en présence d'un premier catalyseur métallique comprenant une phase active hydrodéshydrogénante constituée d'au moins un métal du groupe VIII et/ou au moins un métal du groupe VIB et un support minéral amorphe et b) une deuxième étape, dite deuxième étape de traitement, opérant en présence d'un deuxième catalyseur sulfuré comprenant une phase active hydrodéshydrogénante constituée d'au moins un métal non noble du groupe VIII et/ou au moins un métal du groupe VIB et un support minéral amorphe.
