  • Process for preparing a mixed metal catalyst composition
    Patent number: 6534437
    Abstract: The invention pertains to a process for preparing a catalyst composition comprising bulk catalyst particles comprising at least one Group VIII non-noble metal and at least two Group VIB metals. The process comprises combining and reacting at least one Group VIII non-noble metal component with at least two Group VIB metal components in the presence of a protic liquid, with at least one of the metal components remaining at least partly in the solid state during the entire process. The Group VIII and Group VIB metals comprise from about 50 wt. % to about 100 wt. %, calculated as oxides, of the total weight of said bulk catalyst particles, with the solubility of those of the metal components which are at least partly in the solid state during the reaction being less than 0.05 mol/100 ml water at 18° C.
    Type: Grant

  • Process for the hydroprocessing of a hydrocarbon feedstock using a mixed metal catalyst composition
    Publication number: 20020065441
    Abstract: The invention pertains to a process for the hydroprocessing of a hydrocarbon feedstock wherein a catalyst composition is contacted with the feedstock. The catalyst composition comprises bulk catalyst particles comprising at least one Group VIII non-noble metal and at least two Group VIB metals made by a process comprising combining and reacting at least one Group VIII non-noble metal component with at least two Group VIB metal components in the presence of a protic liquid, with at least one of the metal components remaining at least partly in the solid state during the entire process.
