The present invention pertains to a catalyst composition comprising at least one non-noble Group VIII metal component, at least two Group VIB metal components, and at least about 1 wt. % of a combustible binder material selected from combustible binders and precursors thereof, the Group VIII and Group VIB metal components making up at least about 50 wt. % of the catalyst composition, calculated as oxides. The invention also pertains to a process for preparing the catalyst, to its use in hydroprocessing and to its recycling. The catalyst according to the invention has a higher strength than corresponding binder-free catalysts, and are easier to recycle than catalysts containing a non-combustible binder.

What is claimed is: 1. A catalyst composition comprising at least one non-noble Group VIII metal component, at least two Group VIB metal components, and at least 1 wt. % of a combustible binder material, the Group VIII and Croup VIB metal components, calculated as oxides, making up at least 90 wt.
What is claimed is: 1. A catalyst composition comprising at least one non-noble Group VIII metal component, at least two Group VIB metal components, and at least 1 wt. % of a combustible binder material, the Group VIII and Croup VIB metal components, calculated as oxides, making up at least 90 wt. % of the catalyst composition, the combustible binder comprising at least 70 wt. % of carbon and comprising an at least partly carbonized organic polymer. 2. The catalyst composition of claim 1 which consists essentially of at least one non-noble Group VIII metal component, at least two Group VIB metal components, and at least about 1 wt. % of a combustible binder material. 3. The catalyst composition of claim 1 wherein the Group VIII non-noble metal component comprises cobalt, nickel, iron, or mixtures thereof. 4. The catalyst composition of claim 1 wherein nickel and cobalt make up at least about 50 wt. % of the total of Group VIII non-noble metal components calculated as oxides. 5. The catalyst composition of claim 4 wherein nickel and cobalt make up at least about 70 wt. % of the total of Group VIII non-noble metal components calculated as oxides. 6. The catalyst composition of claim 5 wherein nickel and cobalt make up at least about 90 wt. % of the total of Group VIII non-noble metal components calculated as oxides. 7.

The catalyst composition of claim 9 wherein molybdenum and tungsten make up at least 90 wt. % of the total of Group VIB metal components, calculated as oxides. 11. The catalyst composition of claim 1 wherein the combustible binder material comprises an organic polymer which, upon pyrolysis, comprises carbon as its major component. 12. The catalyst composition of claim 11 wherein the organic polymer is selected from the group consisting of polyacrylonitriles, bakelite, polyamides, polyurethanes, cellulose and derivatives thereof, hemicellulosic materials, polyfurfuryl alcohol, styrene-divinylbenzene copolymers, phenol resins, furan resins, polyimide resins, polyphenylene resins, phenolic foams, and polyurethane foams. 13. A catalyst composition for the hydroprocessing of hydrocarbon feedstocks comprising at least one non-noble Group VIII metal component, at least two Group VIB metal components, and at least about 1 wt. % of a combustible binder, the Group VIII and Group VIB metal components making up at least about 90 wt. % of the catalyst composition, calculated as oxides, wherein the Group VIB metal component comprises molybdenum and tungsten, wherein the combustible binder comprises at least 70 wt. % of carbon and comprises an at least partially carbonized organic polymer.
