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: CSL-P-5033 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.
