Process for preparing a group V111-metal containing catalyst, use thereof for preparing an alkenyl carboxylate

A fluid bed process for the manufacture of vinyl acetate from ethylene, acetic acid and oxygen comprising feeding ethylene and acetic acid into a fluid bed reactor through a first inlet, introducing the oxygen into the reactor through a second inlet, co-joining the oxygen, ethylene and acetic acid in the reactor in contact with a fluid bed catalyst to produce vinyl acetate. The particle size diameter of the particulate catalyst material has a range of 60% of the particles being below 200 microns (0.1 mm) with no more than 40% of the particles being below 40 microns (0.04 mm).

Fluid bed process for the acetoxylation of ethylene in the production of vinyl acetate

A process for the preparation of an alkylene glycol by reacting an alkylene oxide with water in the presence of a solid catalytic composition which includes a strongly basic ion exchange resin coordinated with one or more anions, and a stabilising additive which is an acidic ion exchange resin. Preferably the acidic ion exchange resin is of the weakly acidic methacrylate type.

A process of producing a fluid bed oxacylation catalyst for olefins and diolefins having the following formula Pd-M-A where M=Au, Cd, Bi, Cu, Mn, Fe, Co, Ce, U and mixtures thereof, A=an alkali metal or mixture thereof, and M is present in the range of from 0 to 5 wt %, comprising milling a fixed bed oxacylation catalyst precursor comprising Pd-M on a fixed support with a fluid bed catalyst aqueous binder material to form a uniform aqueous slurry, drying the aqueous slurry to remove the water to form microspheroidal particles of solid fluid bed catalyst precursor, impregnating the microspheroidal particles with a solution of alkali metal salt to form the fluid bed catalyst. The catalyst is particularly useful in the manufacture of vinyl acetate from ethylene, acetic acid and oxygen.

A process for the manufacture of a Pd/Au/alkali metal catalyst, preferably a fluid bed catalyst used in the production of vinyl acetate comprising impregnating a microspheroidal support with a hydroxy-free metal salt solution of Pd and Au substantially free of barium and halide, reducing said salts to deposit Pd and Au on said support surface and impregnating said support with a halide-free metal salt of an alkali metal (preferably potassium).

Acetic acid from ethylene

A shell impregnated catalyst for use in the production of vinyl acetate from ethylene, acetic acid and an oxygen containing gas is provided. The catalyst has a productivity of greater than 661 grams of vinyl acetate per hour per liter of catalyst at 150.degree. C. and consists essentially of:

Catalysts and processes for the manufacture of vinyl acetate

Low molecular weight hydrocarbons are produced by contacting carbon monoxide and hydrogen at elevated temperatures and pressures with a catalyst comprising oxides of chromium, molybdenum and/or tungsten, copper, thorium or uranium and at least one alkali or alkaline earth metal. Catalysts are provided which are prepared by the procedure of adding an alkali or alkaline earth metal carbonate to an aqueous solution or slurry containing decomposable salts of thorium or uranium and copper chromate, copper tungstate and/or copper molybdate to form a precipitate. The precipitate is heated, neutralized, dried and thereafter calcined and reduced.
