The invention relates to a nickel tungsten bulk catalyst, to a process for the manufacture of said catalyst and to the use of said catalyst for the hydrotreatment, in particular the hydrodesulphurisation and hydrodenitrogenation of hydrocarbon feedstock. The catalyst comprises nickel tungsten metal oxidic particles obtainable by a process comprising forming a slurry of a first solid metal compound comprising Group VNI metal nickel and a second solid metal compound comprising Group VIB metal tungsten in a protic liquid, reacting the first and second solid metal compounds at elevated temperature whereby the first and second solid metal compounds remain at least partly in the solid state during the entire reaction to form the nickel tungsten oxidic bulk catalyst.

A stacked bed catalyst system comprising at least one first catalyst selected from conventional hydrotreating catalyst having an average pore diameter of greater than about 10 nm and at least one second catalyst comprising a bulk metal hydrotreating catalyst comprised of at least one Group VIII non-noble metal and at least one Group VIB metal and optionally a binder material.

Hydrotreating catalyst system suitable for use in hydrotreating hydrocarbonaceous feedstreams

A process for producing lube oil basestocks involving solvent extracting a waxy feed to produce at least a lube oil boiling range raffinate, hydrotreating the lube oil raffinate to produce a hydrotreated raffinate, and dewaxing the hydrotreated raffinate.

The use of a controlled amount of water in a hydrogenation stage of the oxo process for the production of alcohols which uses at least two reactors in series improves the efficiency of the hydrogenation reaction and catalyst life as does a reduction in the amount of sulphur, chlorine and hydroformylation catalyst residues in the feed to hydrogenation.

The invention relates to a hydrocracking process for hydrocracking petroleum and chemical feedstocks using bulk Group VIII/VIB catalysts. Preferred catalysts include those comprised of Ni&#x2014;Mo&#x2014;W.

Hydrocracking process using bulk group VIII/Group VIB catalysts

A process for hydroprocessing petroleum and chemical feedstocks by use of a bulk multimetallic catalyst comprised of at least one Group VIII non-noble metal and at least one, preferably two Group VIB metal wherein the ratio of Group VIB metal to Group VIII metal is from about 10:1 to 1:10.

Hydroprocessing using bulk Group VIII/Group VIB catalysts

A process for hydrofining a lubricating oil feedstock comprising contacting the feedstock with a hydrofining catalyst in a hydrofining zone under hydrofining conditions wherein the hydrofining catalyst comprises a bulk metal catalyst containing non-noble Group VIII metal molybdate in which at least a portion but less than all of the molybdenum is replaced by tungsten.

Hydrofining process using bulk group VIII/Group VIB catalysts

A method for upgrading a naphtha feed to a naphtha product containing less than about 10 wppm of nitrogen and less than about 15 wppm sulfur, the method comprising contacting said naphtha feed with hydrogen in the presence of a bulk multimetallic catalyst under effective reactor conditions to hydrodesulfurize and hydrodenitrogenize said naphtha feed to produce said naphtha product, wherein said bulk multimetallic catalyst comprises at least one Group VIII non-noble metal and at least two Group VIB metals.

Process for upgrading naphtha

A two stage hydrodesulfurizing process for producing low sulfur distillates. A distillate boiling range feedstock containing in excess of about 3,000 wppm sulfur is hydrodesulfurized in a first hydrodesulfurizing stage containing one or more reaction zones in the presence of hydrogen and a hydrodesulfurizing catalyst. The liquid product stream thereof is passed to a first separation stage wherein a vapor phase product stream and a liquid product stream are produced. The liquid product stream, which has a substantially lower sulfur and nitrogen content then the original feedstream is passed to a second hydrodesulfurizing stage also containing one or more reaction zones where it is reacted in the presence of hydrogen and a second hydrodesulfurizing catalyst at hydrodesulfurizing conditions. The catalyst in any one or more reaction zones is a bulk multimetallic catalyst comprised of at least one Group VIII non-noble metal and at least two Group VIB metals.

Two stage process for hydrodesulfurizing distillates using bulk multimetallic catalyst

A two stage hydrodesulfurizing process for producing low sulfur distillates. A distillate boiling range feedstock containing in excess of about 3,000 wppm sulfur is hydrodesulfurized in a first hydrodesulfurizing stage containing one or more reaction zones in the presence of hydrogen and a hydrodesulfurizing catalyst. The liquid product stream thereof is passed to a first separation stage wherein a vapor phase product stream and a liquid product stream are produced. The liquid product stream, which has a substantially lower sulfur and nitrogen content than the original feedstream is passed to a second hydrodesulfurizing stage also containing one or more reaction zones where it is reacted in the presence of hydrogen and a second hydrodesulfurizing catalyst at hydrodesulfurizing conditions. The catalyst in any one or more reaction zones is a bulk multimetallic catalyst comprised of at lease one Group VIII non-noble metal and at least two Group VIB metals.

Hydrotreating using bulk multimetallic catalysts

A process for preparing a lubricating oil basestock containing at least about 90% saturates. The process employs a bulk catalyst comprising at least one non-noble Group VIII metal and two Group VIB metals and wherein said metal catalyst further comprises a non-noble Group VIII molybdate in which at least a portion but less than all of molybdenum is replaced by tungsten.

Hydroprocessing using bulk group VIII/group vib catalysts

This invention provides a process for hydrotreating hydrocarbon resins, which process comprises contacting a feedstock comprising a hydrocarbon resin or rosin, under suitable hydrotreating conditions, with a bulk multimetallic catalyst comprised of at least one Group VIII non-noble metal and at least two Group VIB metals and wherein the ratio of Group VIB metal to Group VIII non-noble metal is from about 10:1 to about 1:10. The process according to the invention can achieve increased hydrocarbon resin productivity through increase in throughput volumes and effective catalyst lifetimes. The process of the invention is desirably practiced with a bulk catalyst consisting of only the combination of the metal species with the active metal components. The absence of carrier substrates largely removes the possibility of halogen accumulation on substrate surfaces that, in turn, can acidify metal catalysts such that additional, progressive cracking of the hydrocarbon resin molecules occurs.

Hydrogenation process for hydrocarbon resins

The invention pertains to a process for the hydroprocessing of a hydrocarbon feedstock wherein said feedstock is contacted at hydroprocessing conditions with a catalyst composition which comprises bulk catalyst particles which comprise at least one Group VIII non-noble metal and at least two Group VIB metals. The Group VIII and Group VIB metals comprise from about 50 wt. % to about 100 wt. %, calculated as oxides, of the total weight of the bulk catalyst particles. The metals are present in the catalyst composition in their oxidic and/or sulfidic state. The catalyst composition has an X-ray diffraction pattern in which the characteristic full width at half maximum does not exceed 2.5&deg; when the Group VIB metals are molybdenum, tungsten, and, optionally, chromium, or does not exceed 4.0&deg; when the Group VIB metals are molybdenum and chromium or tungsten and chromium.

Process for preparing a mixed metal catalyst composition

The present invention relates to a process for the preparation of a hydroprocessing catalyst, to the catalyst composition obtainable by said process, and to the use of said catalyst composition in hydroprocessing applications. The process comprises the steps of combining and reacting at least one Group VIII non-noble metal component in solution and at least two Group VIB metal components in solution in a reaction mixture to obtain an oxygen-stable precipitate, and sulfiding the precipitate.
