Methods are provided for forming supported catalyst compositions and/or corresponding intermediate catalyst products. The catalyst compositions have improved activity for hydroprocessing of distillate boiling range feeds under hydroprocessing conditions where the hydrogen partial pressure in the hydroprocessing environment is reduced or minimized. The catalyst compositions can correspond to supported CoMo catalysts. The improved activity for hydroprocessing under lower pressure conditions is unexpectedly achieved by using a plurality of treatments with organic compounds during the catalyst formation process.

Low pressure hydroprocessing catalyst

Catalyst systems are provided, along with corresponding methods, for single stage conversion of synthesis gas to fuel boiling range products with increased selectivity for either naphtha production (C-C) or distillate production (C-C). The increased selectivity for naphtha production or distillate production is provided in conjunction with a reduced selectivity for higher boiling range components (C).

Conversion of synthesis gas to liquid fuels

A method of producing a hydrogenation catalyst, for example, a phthalate hydrogenation catalyst, comprising contacting a silica support having a medium pore size of at least about 10 nm with an acid to produce a treated silica support, and depositing a noble metal, preferably ruthenium, on the treated silica support to produce a noble metal-containing silica support, and optionally contacting the noble metal-containing silica support with a chelating agent to form the hydrogenation catalyst; a hydrogenation catalyst prepared by that method; and a method of hydrogenating unsaturated hydrocarbons, such as, phthalates, in which an unsaturated hydrocarbon is contacted with hydrogen gas in the presence of the hydrogenation catalyst of the invention.

Hydrogenation catalyst, its method of preparation and use

Systems and methods are provided for hydroconversion of a heavy oil feed under slurry hydroprocessing conditions and/or solvent assisted hydroprocessing conditions. The systems and methods for slurry hydroconversion can include the use of a configuration that can allow for improved separation of catalyst particles from the slurry hydroprocessing effluent. In addition to allowing for improved catalyst recycle, an amount of fines in the slurry hydroconversion effluent can be reduced or minimized. This can facilitate further processing or handling of any 'pitch' generated during the slurry hydroconversion. The systems and methods for solvent assisted hydroprocessing can include processing of a heavy oil feed in conjunction with a high solvency dispersive power crude.

Processing of heavy hydrocarbon feeds

Methods are provided for modifying hydrogenation catalysts having silica supports (or other non-alumina supports) with additional alumina, and using such catalysts to achieve unexpectedly superior hydrogenation of feedstocks. The modified hydrogenation catalysts can have a relatively low cracking activity while providing an increased activity for hydrogenation.

Method and system for producing low aromatic hydrocarbon products

Noble metal hydrogenation catalysts and aromatic saturation methods

A method of preparing a hydrogenation catalyst, for example, a phthalate hydrogenation catalyst, comprising contacting a silica support having a median pore size of at least about 10 nm with a silylating agent to form an at least partially coated silica support, calcining said coated silica support to form a treated silica support, and depositing a noble metal, preferably ruthenium, on the treated silica support, and optionally contacting the treated silica support with an optional chelating agent to form the hydrogenation catalyst; a hydrogenation catalyst prepared by that method; and a method of hydrogenating unsaturated hydrocarbons, such as phthalates, in which an unsaturated hydrocarbon is contacted with hydrogen gas in the presence of the hydrogenation catalyst of the invention.

The precursor of a hydroprocessing catalyst is made by impregnating a metal oxide component comprising at least one metal from Group 6 of the Periodic Table and at least one metal from Groups 8-10 of the Periodic Table with an amide formed from a first organic compound containing at least one amine group, and a second organic compound containing at least one carboxylic acid group. Following impregnation heat treatment follows to form in situ generated unsaturation additional to that in the two organic compounds. The catalyst precursor is sulfided to form an active, sulfide hydroprocessing catalyst.

Hydroprocessing catalysts and their production

Noble metal hydrogenation catalysts with low cracking activity

A process for ring hydrogenation of a benzenepolycarboxylic acid or derivative thereof, includes contacting a feed stream comprising the acid or derivative thereof with a hydrogen containing gas in the presence of a catalyst under hydrogenation conditions to produce a hydrogenated product, wherein the catalyst contains rhodium and ruthenium.

The invention relates to a method for hydroprocessing hydrocarbon feedstocks, said process comprising contacting a hydrocarbon feedstock under hydroprocessing conditions with a bulk catalyst composition comprising bulk metal particles that comprise at least one Group VIII non-noble metal, at least one Group VIB metal and nanoparticles. The bulk metal catalyst composition comprises bulk metal particles that may be prepared by a manufacturing process comprising the steps of combining in a reaction mixture (i) dispersible nanoparticles having a dimension of less than about 1 &#x3bc;m upon being dispersed in a liquid, (ii) at least one Group VIII non-noble metal compound, (iii) at least one Group VIB metal compound, and (iv) a protic liquid; and reacting the at least one Group VIII non-noble metal compound and the at least one Group VIB metal in the presence of the nanoparticles.

Hydrocarbon hydroprocessing using bulk catalyst composition

Feedstocks containing biocomponent materials are coprocessed with mineral feeds using a Group VI metal catalyst prior to hydrodesulfurization of the feedstocks. The Group VI metal catalyst is optionally a physically promoted Group VI metal catalyst.
