The objective of the present invention is a polyvalent bifunctional catalyst and the process of its realization. A catalyst characterized by the fact that it contains, over a TiO support, an oxide or a mixture of metallic oxides of MC type obtained by reduction of the corresponding MC oxides, the metal(s) forming the MO oxides are chosen from the group formed by W and Mo.

The present invention relates to new catalysts for the hydrotreatment of hydrocarbons, their preparation and their application. The catalyst for the hydrotreatment of hydrocarbons, according to the present invention, incorporates a refractory inorganic support combined with an active phase comprising a layer of uranium oxide and at least one oxide of a Group VIII metal. The active phase comprises a layer of uranium oxide fixed with a homogenous distribution on the said support through the intermediacy of direct --O-- bonds resulting from an impregnation of the support with the aid of an ethanolic solution of uranyl acetylacetonate.
