  • Polyvalent bifunctional catalyst and the process of realization of such a catalyst
    Patent number: 6781022
    Abstract: 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 TiO2 support, an oxide or a mixture of metallic oxides of MC2 type obtained by reduction of the corresponding MC3 oxides, the metal(s) forming the MO2 oxides are chosen from the group formed by W and Mo.

  • Catalysts for the hydrotreatment of hydrocarbons and their preparation
    Patent number: 4581344
    Abstract: 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.
