The present invention relates to a process for preparing alkanolamines and ethyleneamines in the liquid phase, by reacting ethylene glycol and/or monoethanolamine with ammonia in the presence of an amination catalyst which is obtained by reducing a catalyst precursor, wherein the preparation of the catalyst precursor comprises a step a) in which a catalyst precursor comprising one or more catalytically active components of Sn, Cu and Ni, and a step b) in which the catalyst precursor prepared in step a) is contacted with a soluble Re compound.

A process for the production of formaldehyde from methanol comprising the steps of: feeding to a reactor a feed stream comprising the methanol and an oxygen-containing gas; reacting the methanol in the gas phase with the oxygen-containing gas in the reactor in the presence of a catalyst comprising oxides of iron and molybdenum; and recovering a formaldehyde reactor outlet stream from the reactor, the formaldehyde reactor outlet stream comprising formaldehyde and carbon monoxide. The catalyst comprises copper in an amount of at least 0.025 wt %, or at least 0.05 wt %, of the catalyst and in that the molar ratio of carbon monoxide to formaldehyde in the formaldehyde reactor outlet stream is at least 5% less than the molar ratio of carbon monoxide to formaldehyde in the formaldehyde reactor outlet stream in the same process using a catalyst containing essentially no copper.

The present invention relates to a process for producing alcohols by hydrogenation of C9 aldehydes. The process according to the invention is performed in two consecutive hydrogenation stages, wherein the first hydrogenation stage employs an activated metal catalyst based on a nickel metal foam and the second stage employs a supported catalyst containing a catalytically active component from the group consisting of nickel, copper, chromium and mixtures thereof.

Oxidative dehydrogenation catalysts including mixed oxides of Mo, V, Nb, Te, and optionally a promoter may be dissolved in aqueous solutions of oxalic acid. This permits the removal of catalyst and catalyst residues from reactors for the oxidative dehydrogenation of paraffins and particularly ethane.

A process for preparing a catalyst comprises coating substantial internal surfaces of porous inorganic powders with titanium oxide to form titanium oxide-coated inorganic powders. After the coating, an extrudate comprising the titanium oxide-coated inorganic powders is formed and calcined to form a catalyst support. Then, the catalyst support is impregnated with a solution containing one or more salts of metal selected from the group consisting of molybdenum, cobalt, and nickel.
