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).

Disclosed is a process for making acetic acid which comprises oxidizing ethane with molecular oxygen in a reaction zone at a pressure of at least 100 psig while the reactants are in contact with a solid catalyst having the elements and relative atomic proportions indicated by the empirical formula:

Catalytic oxidation of ethane to acetic acid

A novel system for the preparation of maleic anhydride by catalytic oxidation of a hydrocarbon such as butane wherein the catalyst system comprising a mixture of (1) a mixed vanadium-phosphate catalyst and (2) a noncatalytic material comprising an oxide of a Group IA-IIIA element, Pb, In, Sb, Sn, Tl, Bi or mixtures thereof.

Improved supported, mixed-metal oxide oxidation catalysts are prepared by conditioning a devolatilized catalyst precursor with an alcohol prior to calacining the precursor to a finished catalyst. For example, a promoted bismuth phosphomolybdate oxidation catalyst useful for converting propylene to acrolein demonstrates enhanced performance characteristics when the devolatilized catalyst precursor is subjected to boiling ethanol prior to calcining it to a finished catalyst.

A method for preparing a molecular sieving metallosilicate is disclosed which comprises

Synthesis of molecular sieving metallosilicates using silica-transition

A metal oxide catalyst of high surface area is prepared by dissolving a metal salt in a polar organic solvent, precipitating the metal from solution in a form thermally decomposable to the oxide by means of a precipitating agent which is sparingly soluble in the solution, separating the precipitate, drying and calcining to form the metal oxide. The technique is particularly suitable for the preparation of Group VIIIA metal oxide catalysts which are useful for the conversion of carbon monoxide to hydrocarbons.

Method for the digestion-precipitation of high activity catalysts

A process for the reductive deposition of polyoxometallate complexes on supports. The process includes the steps of forming a solution of at least one polyoxometallate compound in a solvent, said compound having the formula A.sub.a (L.sub.l M.sub.m J.sub.z O.sub.y), adding a quantity of a support material having electronic conductivity to the solution, charging the solution containing the support material to an electrolytic cell in contact with the cathode thereof, the cell having a separate compartment for the anode, passing a current of from about 0.1 to about 500 mA/cm.sup.2 of electrode area through the cell whereby the support material receives a deposit of a polyoxometallate wherein the average oxidation state of the metals therein has been reduced to a valence greater than zero and, thereafter separating and recovering the support material carrying the reduced metallate complex.
