Abstract: PROBLEM TO BE SOLVED: To produce a catalyst useful for ammoxidation of propane or propylene to acrylonitrile at a low cost, by producing a compound having a specified formula, reacting a mixture of water-soluble vanadate and Sb2 O3 , and then heating and drying the resultant reaction products. SOLUTION: The catalyst having a formula; Va Sbb Mm Nn Ox ; is produced. In the formula, (a) stands for 0.01-2, (b) for 0.5-4, (m) for 0.01-3, (n) for 0-1, M for Sn, Ti, Fe, Cu, Mn, Ga, Co, or their mixtures. N for Li, Mg, Sr, Ca, Ba, Co, or their mixtures. While being stirred for a sufficient time to produce a catalyst precursor, a water-soluble vanadate, Sb2 O3 , and aqueous mixture containing M promoting agent if necessary are heated to the temperature range from its reflux temperature to 250 deg.C in the atmospheric pressure. Then, the obtained catalyst precursor is dried and after that, the resultant precursor is calcined to produced a desired catalyst.

Abstract: 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 one or more inlets, introducing the oxygen into the reactor through at least one further 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 preferably has a range of 60% of the particles being below 200 microns (0.2 mm) with no more than 40% of the particles being below 40 microns (0.04 mm).

Abstract: A process for the preparation of a fluid bed vinyl acetate (VAM) catalyst comprising impregnating a support comprising a mixture of substantially inert microspheroidal particles with a solution comprising a halide-free metal salt of Pd and M, wherein M comprises Ba, Au, La, Nb, Ce, Zn, Pb, Ca, Sr, Sb or mixtures thereof, reducing the metal salts to form a deposit of Pd and M on the support surface and impregnating the support with at least one halide-free alkali metal salt. At least 50% of the particles used for the microspheroidal support have a particle size below 100 microns, preferably below 60 microns. The pore volume of these particles is from 0.2 to 0.7cm /g and the surface area is from 100 to 200 m /g.
