A supported gold catalyst is used for selective oxidation. In particular, an alcohol or ketone is oxidized to produce the corresponding carboxylic acid, an alcohol is oxidized to produce the corresponding ketone, and xylene is oxidized to produce the corresponding mono-alcohol or di-alcohol.

Gold catalyst for selective oxidation

Disclosed is a process for oxidizing organic compounds using hydrogen peroxide to oxidize an oxidizable organic substrate in the presence of a silylated peroxide-activating metal/silica-containing catalyst and to a method of preparing such a catalyst.

Process for the selective oxidation of organic compounds

An improved catalytic process for decomposing alkyl or aromatic hydroperoxides is disclosed which utilizes a caalytic amount of a heterogeneous Au catalyst that has been treated with an organosilicon reagent.

Hydroperoxide decomposition catalyst

A Fischer-Tropsch catalyst comprising a catalytically active first metal selected from the group consisting of at least one metal selected from the group consisting of iron, nickel, cobalt, chromium, and mixtures thereof, at least one second metal selected from the group consisting of silver, iron, zinc, copper, platinum, zirconium and combinations thereof; and a matrix structure comprising a polymer selected from the group consisting of polyacrylates and polymethacrylates. The first and second metals are incorporated into the polymer.

Fischer-Tropsch processes and catalysts using polyacrylate matrix structures

A Fischer-Tropsch process for producing hydrocarbons, comprising contacting a feed stream comprising hydrogen and carbon monoxide with a catalyst in a reaction zone maintained at conversion-promoting conditions effective to produce an effluent stream comprising hydrocarbons, wherein the catalyst comprises at least one catalytically active metal selected from the group consisting of cobalt, iron, nickel and ruthenium and combinations thereof, a catalyst support, and silver.

Process for the preparation of hydrocarbons

Mesoporous materials containing a Group IIA metal are prepared by a sol-gel type techniques.

Group IIA containing mesoporous materials

This invention provides a process for producing hydrocarbons. The process involves contacting a feed stream comprising hydrogen and carbon monoxide with a catalyst in a reaction zone maintained at conversion-promoting conditions effective to produce an effluent stream comprising hydrocarbons, and uses a catalyst including (a) at least one catalytic metal for Fischer-Tropsch reactions (e.g., iron, cobalt, nickel and/or ruthenium) and (b) a non-layered mesoporous support which exhibits an X-ray diffraction after calcination that has at least one peak at a d-spacing of greater than 18 &angst;ngstrom units.

Fischer-Tropsch processes using catalysts on mesoporous supports

Silylated organic gels can be prepared by the removing substantially all of the water from polyhydroxy benzene-formaldehyde gels, followed by silylation. These silylated organic gel compositions comprise from about 0.01% to about 25% by weight silicon.

Organic gels

A method for making monomethylamine, dimethylamine and trimethylamine, in which methanol and/or dimethylether and ammonia are contacted in the presence of an acidic zeolite chabazite catalyst is disclosed. The method suppresses the production of trimethylamine and optimizes dimethylamine and monomethylamine yields.

Method of making methylamines using chabazite catalysts

The present invention relates to the selectivity of production of methylamines from methanol and/or dimethylether and ammonia using at catalytic amount of acidic molecular sieve.
