The invention relates to a process for upgrading hydrocarbonaceous feedstreams by hydroprocessing using bulk bimetallic catalysts. More particularly, the invention relates to a catalytic hydrotreating process for the removal of sulfur and nitrogen from a hydrocarbon feed such as a fuel or a lubricating oil feed. The catalyst is a bulk catalyst containing at leas one Group VIII metal and at least one Group VIB metal. The catalyst is prepared hydrothermally.

What is claimed is: 1. A process for hydroprocessing a hydrocarbon feed, the process comprising contacting the feed with hydrogen in the presence of a catalytically effective amount of a bulk metal catalyst under catalytic conversion conditions to form a hydroprocessed product, the bulk metal catalyst comprising metal oxidic particles containing niobium as a Group V metal, only one Group VIB metal, and only one Group VIII metals, the bulk metal catalyst being made by: (i) combining in a reaction mixture one or more first compounds comprising only one Group VIII metal, one or more second compounds comprising only one Group VIB metal, and one or more third compounds comprising niobium as a Group V metal in the presence of a protic liquid, wherein the Group VIII metal to Group VIB metal molar ratio is between about 0.1 and about 1.5, and wherein the Group V metal content is at least about 0.1 mol % and less than about 10 mol %; and (ii) reacting the compounds under hydrothermal conditions to form metal oxidic particles, wherein a corresponding atmospheric product is obtained under identical process conditions using a corresponding atmospheric bulk metal catalyst having identical ingredients and an identical method of manufacture as the bulk metal catalyst except that the compounds were reacted at atmospheric conditions instead of hydrothermal conditions, and wherein the hydroprocessed product has (a) a lower sulfur content than the corresponding atmospheric product, due to the bulk metal catalyst having an increased hydrodesulfurization activity compared to the corresponding atmospheric bulk metal catalyst, (b) a lower nitrogen content than the corresponding atmospheric product, due to the bulk metal catalyst having an increased hydrodenitrogenation activity compared to the corresponding atmospheric bulk metal catalyst, or (c) both (a) and (b). 2. The process of claim 1, wherein the hydrothermal conditions include heating the reaction mixture at a temperature above the atmospheric boiling point of the protic liquid. 3. The process of claim 1, wherein the hydrothermal conditions include heating the reaction mixture in a sealed reaction vessel. 4. The process of claim 1, wherein the protic liquid is water and the reaction is done under hydrothermal conditions at a reaction temperature above about 100° C. and under autogenic pressure in a sealed vessel. 5. The process of claim 1, wherein the Group VIII metal to Group VIB metal mole ratio is between about 0.2 and about 1.0. 6. The process of any of claim 1, wherein the one or more first metal compounds and the one or more second metal compounds remain at least partly in the solid state during the entire reaction. 7. The process of claim 1, wherein the metal oxidic particles are dried and/or heat treated at a temperature below about 375° C. 8. The process of claim 1, wherein the metal oxidic particles comprise nickel as the only one Group VIII metal and tungsten as the only one Group VIB metal. 9. The process of claim 1, further comprising the step of treating the bulk metal catalyst with a sulfur-containing compound. 10. The process of claim 1, further comprising the step of combining the metal oxidic particles with one or several binding materials so that the bulk metal catalyst comprises at least about 60 wt % metal oxidic particles. 11. A process for hydroprocessing a hydrocarbon feed, the process comprising contacting the feed with hydrogen in the presence of a catalytically effective amount of a bulk metal catalyst under catalytic conversion conditions to form a hydroprocessed product, the bulk metal catalyst comprising metal oxidic particles containing at least about 0.1 mol % and less than about 10 mol % of a Group V metal, only tungsten as Group VIB metal, and only nickel as Group VIII metal, and the mole ratio of nickel to tungsten is between about 0.2 and about 1.5, wherein a corresponding atmospheric product is obtained under identical process conditions using a corresponding atmospheric bulk metal catalyst having identical ingredients and an identical method of manufacture as the bulk metal catalyst except that the compounds were reacted at atmospheric conditions instead of hydrothermal conditions, and wherein the hydroprocessed product has (a) a lower sulfur content than the corresponding atmospheric product, due to the bulk metal catalyst having an increased hydrodesulfurization activity compared to the corresponding atmospheric bulk metal catalyst, (b) a lower nitrogen content than the corresponding atmospheric product, due to the bulk metal catalyst having an increased hydrodenitrogenation activity compared to the corresponding atmospheric bulk metal catalyst, or (c) both (a) and (b). 12. The process of claim 11, wherein the mole ratio of nickel to tungsten is between about 0.2 and about 1.0. 13. The process of claim 1, further comprising forming a product containing hydrocarbon and at least one of sulfur and nitrogen, and then separating the hydrocarbon product. 14. The process of claim 13, wherein the hydrocarbon feed contains organically-bound sulfur and organically-bound nitrogen, and wherein the catalytic conversion conditions are hydrotreating conditions effective for converting at least a portion of organically-bound sulfur and organically-bound nitrogen in the feed to hydrogen sulfide and ammonia respectively. 15. The process of claim 14, wherein the catalytic conversion conditions comprise at least one of (i) hydrocracking and (ii) hydrogenating the hydrocarbon feed. 16. The process of any of claim 13, wherein the separated hydrocarbon product is used neat or blended to make at least one of (i) a fuel oil, (ii) a diesel oil, (iii) a lubricating oil, or (iv) a lubricating oil basestock.
