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

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.

Process for hydrogenation of benzenepolycarboxylic acids and derivatives thereof

A process is described for producing a catalyst composition comprising an iridium component dispersed on a support. In the process, silica- o group to form an organic iridium complex on the support. The treated support is then heated in an oxidizing atmosphere at a temperature of about 325&#xb0; C. to about 475&#xb0; C. to partially decompose the organic metal complex on the support. The treated support is then heated in a reducing atmosphere at a temperature of about 350&#xb0; C. to about 500&#xb0; C. to convert the partially decomposed organic iridium complex into the desired iridium component.

Iridium-containing catalysts, their production and use

In a process for the dehydrogenation of dehydrogenatable hydrocarbons, a feed comprising dehydrogenatable hydrocarbons is contacted with a catalyst comprising a support and a dehydrogenation component under dehydrogenation conditions effective to convert at least a portion of the dehydrogenatable hydrocarbons in the feed. The catalyst is produced by a method comprising treating the support with a liquid composition comprising the dehydrogenation component or a precursor thereof and at least one organic dispersant selected from an amino alcohol and an amino acid.

Dehydrogenation process

In a dehydrogenation process a hydrocarbon stream comprising at least one non-aromatic six-membered ring compound and at least one five-membered ring compound is contacted with a dehydrogenation catalyst produced by a method comprising treating the support with a liquid composition comprising the dehydrogenation component or a precursor thereof and at least one organic dispersant selected from an amino alcohol and an amino acid. The contacting is conducted under conditions effective to convert at least a portion of the at least one non-aromatic six-membered ring compound in the hydrocarbon stream to benzene and to convert at least a portion of the at least one five-membered ring compound in the hydrocarbon stream to paraffins.

Described herein is a catalyst precursor composition comprising at least one metal from Group 6 of the Periodic Table of the Elements, at least one metal from Groups 8-10 of the Periodic Table of the Elements, and a reaction product formed from (i) a first organic compound containing at least one amine group, and (ii) a second organic compound separate from said first organic compound and containing at least one carboxylic acid group. A process for preparing the catalyst precursor composition is also described, as is sulfiding the bulk mixed metal oxide catalyst precursor composition to form a hydroprocessing catalyst.

Described herein is a catalyst precursor composition comprising at least one metal from Group 6 of the Periodic Table of the Elements, at least one metal from Groups 8-10 of the Periodic Table of the Elements, and a reaction product formed from (i) a first organic compound containing at least one amine group and at least 10 carbon atoms or (ii) a second organic compound containing at least one carboxylic acid group and at least 10 carbon atoms, but not both, wherein the reaction product contains additional unsaturated carbon atoms, relative to the first or second organic compound, wherein the metals of the catalyst precursor composition are arranged in a crystal lattice, and wherein the reaction product is not located within the crystal lattice. A process for preparing the catalyst precursor composition is also described, as is sulfiding the catalyst precursor composition to form a hydroprocessing catalyst.

A method is provided for preparing a supported cobalt-containing catalyst having substantially homogeneously dispersed, small cobalt crystallites. The method comprises depositing cobalt nitrate on a support and then subjecting the support to a two-step decomposition protocol. In the first step, the support is heated in an oxygen-containing, substantially water-free atmosphere to about 160&#xb0; C. to form an intermediate decomposition product. This intermediate product is then or hydrolyzed and reduced, or hydrolyzed, calcined and reduced.

Preparation of high activity cobalt catalysts, the catalysts and their use

A process for hydrogenating benzenepolycarboxylic acids or derivatives thereof, such as esters and/or anhydrides, is provided.

Hydrogenation of benzene polycarboxylic acids or derivatives thereof

A method is provided for preparing a supported cobalt-containing catalyst having substantially homogenously dispersed, small cobalt crystallites. The method comprises depositing cobalt nitrate on a support and then heating the support in an oxygen-containing, substantially water-free atmosphere to about 160&#xb0; C. to form an intermediate decomposition product. This intermediate decomposition product is then calcined and reduced.

The present invention is directed to a process for hydrogenating one or more organic compounds especially unsaturated organic compounds by bringing the compound into contact with a hydrogen-containing gas in the presence of a catalyst, which comprises one or more catalytically active metals applied to a porous catalyst support. The one or more catalytically active metals having been derived via a decomposed organic complex of the metal on the support, in particular amine complexes of the metal. The decomposed complex may be treated with hydrogen to activate the catalyst before use as a hydrogenation catalyst.

Hydrogenation processes

A process for hydrogenating benzenepolycarboxylic acids or derivatives thereof, such as esters and/or anhydrides, by bringing one or more benzenepolycarboxylic acids or one or more derivatives thereof into contact with a hydrogen-containing gas in the presence of one or more catalytically active metal, such as platinum, palladium ruthenium or mixtures thereof, deposited on a catalyst support comprising one or more ordered mesoporous materials.
