Abstract: Disclosed is a process for oxidizing ethane to acetic acid which comprises feeding ethane and a recycle gas to a fluidized bed reaction zone containing fluidized particulate solid oxidation catalyst, feeding a molecular oxygen-containing gas separately from said ethane to said reaction zone so that said molecular oxygen-containing gas first mixes with the major portion of the combustible hydrocarbon feed gases within the fluidized bed, said process including the steps of (1) cooling the gaseous effluent from the reaction zone, (2) separating most of the acetic acid in liquid form from the effluent gases, leaving a gaseous stream containing nearly all of the carbon oxides contained in said effluent, (3) purging a small portion of said gaseous stream and recycling most of said gaseous stream as part of the feed to said reaction zone, wherein said purging serves to prevent build-up of carbon oxides in the reaction zone, and said recycling serves to maintain a high proportion of carbon oxides in said reaction zone gases, thus aiding in moderating the temperature elevating effect of the highly exothermic oxidation reaction in said reaction zone.

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.

The catalyst is particularly useful in the manufacture of vinyl acetate from ethylene, acetic acid and oxygen.
