A catalyst and/or precatalyst for olefin oligomerization comprising one or more coordination complexes having one or more central palladium metal atoms. Each palladium atom is bonded to four ligand donor atoms. Two of the donor atoms are group 16 elements and two of the donor atoms are group 15 elements. Also provided are neutral or cationic coordination complex dimers, so that the two palladium atoms are both bonded to one or two donor atoms from group 16, and each palladium atom is bonded to two donor atoms from group 15. In some instances, each of the two group 16 donor atoms are oxygen and each of the four group 15 donor atoms are nitrogen.

Air and water tolerant catalyst

The present invention relates to a process for producing methanol and ethanol, wherein the methanol is produced from synthesis gas and the ethanol is produced via the hydrogenation of an ethanoic acid feed; characterized in that the hydrogenation of the ethanoic acid feed is carried out within the same alcohol synthesis unit and in the presence of the same catalyst(s) that is used to produce the methanol from the synthesis gas and wherein the feed introduced to the alcohol synthesis unit comprises synthesis gas and ethanoic acid.

Hydrogenation of ethanoic acid to produce ethanol

Process for reducing the methane selectivity in a Fischer-Tropsch conversion of syngas to hydrocarbons, by using a catalyst composition containing (i) cobalt, either as the elemental metal, oxide, or a compound thermally decomposable to the elemental metal or oxide, (ii) zinc, in the form of the oxide or a compound thermally decomposable to the oxide, and (iii) platinum, in the elemental metal form, or in the form of a compound wherein the amount of platinum metal present in the composition is in the range 0.0001 to 1.50% w/w.

Fischer-tropsch catalyst

Process for the production of a condensed-phase product from one or more gas-phase reactants, by feeding one or more reactants into a reactor, in which reactor the one or more reactants react in the gas-phase in the presence of a solid catalyst having one or more catalyst components to produce at least one product which is in a condensed-phase under reaction conditions. The solid catalyst is present as a bed having two or more regions in which the contact time of the one or more gas-phase reactants with the one or more catalyst components is different.

Process for producing condensed-phase product from one or more gas-phase reactants

A process for the liquid phase carbonylation of an alcohol and/or a reactive derivative thereof in the presence of hydrogen in which there is employed a catalyst comprising rhodium of iridium coordinated with a polydentate ligand.

Carbonylation process using metal-polydentate ligand catalysts

A process for the production of a carboxylic acid and/or the alcohol ester of a carboxylic acid by carbonylating an alcohol and/or a reactive derivative thereof with carbon monoxide employing as the carbonylation catalyst, cobalt, rhodium or iridium coordinated with a tridentate ligand.

Carbonylation process using metal-tridentate ligand catalysts

Acetic acid is produced by oxidation of methane with an oxygen-containing gas in the presence of an acid selected from concentrated sulfuric acid and fuming sulfuric acid, a palladium-containing catalyst and a promoter, preferably a copper or iron salt. The addition of a promoter and Oto a system that includes a palladium-containing catalyst such as PdClincreases the rate of acetic acid formation from methane by more than an order of magnitude as compared with prior art and, in addition, inhibits the precipitation of Pd black.

Process for direct oxidation of methane to acetic acid

Acetyl anhydrides such as acetyl sulfate are produced by a process for comprising contacting methane and carbon dioxide in an anhydrous environment in the presence of effective amounts of a transition metal catalyst and a reaction promoter, and an acid anhydride compound, and optionally an acid. The acetyl anhydride can be contacted with water to produce acetic acid or with an alcohol to produce a product comprising an acetate ester and that may also comprise acetic acid. Optionally, water in stoichiometric amounts or less, with respect to the acetic anhydride, may be fed to a continuous process of this type to produce some acetic acid in situ.
