Catalysts for the production of alkylene oxide by the epoxidation of alkene with oxygen comprise a silver-containing support, and a sufficient amount of cobalt component to enhance at least one of activity and/or efficiency and/or stability as compared to a similar catalyst which does not contain cobalt component.

Alkylene oxide catalysts having enhanced activity and/or stability

This invention relates in part to a processes and catalysts for the conversion of a feedstock comprising carbon monoxide and hydrogen to a product stream comprising at least one of an ester, acid, acid anhydride and mixtures thereof. This invention also relates in part to processes and catalysts for converting an alcohol, ether and/or ether alcohol feedstock to oxygenated products, e.g., esters, acids, acid anhydrides and mixtures thereof. The processes and catalysts are especially suitable for the production of acetic acid and methyl acetate from a synthesis gas feedstock or from an alcohol, ether or ether alcohol feedstock.

Process for preparing oxygenates and catalysts therefor

Processes for preparing oxygenates and catalysts therefor

A process for preparing a supported silver catalyst for the production of alkylene oxide by the vapor phase oxidation of alkylene with an oxygen-containing gas is disclosed and comprises contacting a silver-contacting support with a solution comprising a metal-containing promoter other than alkali metals or alkaline earth metals. The solution is chosen so that the metal-containing promoter has an increased affinity to the silver-containing carrier relative to its affinity to the carrier without silver. Alkene epoxidation catalysts and alkene epoxidation processes are also disclosed.

Supported silver catalyst, and processes for making and using same

Catalysts for the production of alkylene oxide by the epoxidation of alkene with oxygen comprise a silver impregnated support containing a sufficient amount of scandium component to enhance at least one of activity and/or efficiency as compared to a similar catalyst which does not contain scandium component.
