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.

Abstract: A method is disclosed for the preparation of a molecular sieving metallosillicate wherein an aqueous dispersion of colloidal particles comprising contiguous mixtures of silica and at least one oxide of a transition metal is mixed with an effective amount of a mineralizing agent and/or synthesis directing agent to form a gel. The formed gel is maintained at a temperature of about 80.degree.C to about 300.degree.C for a period of time effective to provide the desired molecular sieving metallosillicate.

Abstract: COATED CATALYSTS CONTAINING HIGH LOADING OF ACTIVE PHASE, PARTICULARLY USEFUL IN THE PREPARATION OF MALEIC ANHYDRIDE Catalysts particularly effective in the oxidation of n-butane, n-butenes, 1,3 butadiene and mixtures thereof with molecular oxygen or an oxygen-containing gas in the vapor phase to produce maleic anhydride are provided which comprise an essentially inert, at least partially porous support to which is adhered on its outer surface, catalytically active mixed oxides of vanadium and phosphorus or of vanadium, phosphorus and uranium in an amount greater than 50% to about 80% by weight of the combined support and active oxide.
