  • Integrated process for the production of vinyl acetate and/or acetic acid
    Patent number: 7491843
    Abstract: Acetic acid and/or vinyl acetate are produced by an integrated process which comprises the steps: (a) contacting in a first reaction zone a gaseous feedstock comprising ethylene and/or ethane and optionally steam with a molecular oxygen-containing gas in the presence of a catalyst active for the oxidation of ethylene to acetic acid and/or ethane to acetic acid and ethylene to produce a first product stream comprising acetic acid, water and ethylene (either as unreacted ethylene and/or as co-produced ethylene) and optionally also ethane, carbon monoxide, carbon dioxide and/or nitrogen; (b) contacting in a second reaction zone in the presence or absence of additional ethylene and/or acetic acid at least a portion of the first gaseous product stream comprising at least acetic acid and ethylene and optionally also one or more of water, ethane, carbon monoxide, carbon dioxide and/or nitrogen with a molecular oxygen-containing gas in the presence of a catalyst active for the production of vinyl acetate to produce

  • Integrated process for the production of vinyl acetate and/or acetic acid using a fluidized bed
    Patent number: 6180821
    Abstract: Acetic acid and/or vinyl acetate are produced by an integrated process in which a gaseous feedstock comprising ethylene and/or ethane and optionally steam is contacted in a first reaction zone (step (a)) with a molecular oxygen-containing gas in the presence of a catalyst active for the oxidation of ethylene to acetic acid and/or ethane to acetic acid and ethylene to produce a first product stream comprising acetic acid, water and ethylene (either as unreacted ethylene and/or as co-produced ethylene) and optionally also ethane, carbon monoxide, carbon dioxide and/or nitrogen.

  • Catalysts and processes for the manufacture of vinyl acetate
    Patent number: 5274181
    Abstract: A shell impregnated catalyst for use in the production of vinyl acetate from ethylene, acetic acid and an oxygen containing gas is provided. The catalyst has a productivity of greater than 661 grams of vinyl acetate per hour per liter of catalyst at 150.degree. C. and consists essentially of:(1) a catalyst support having a particle diameter from about 3 to about 7 mm and a pore volume of 0.2 to 1.5 ml per gram(2) palladium and gold distributed in the outermost 1.0 mm thick layer of the catalyst support particles, and(3) from about 3.5 to 9.5% by weight of potassium acetate.The catalyst is characterised by having a gold to palladium weight ratio in the range 0.60 to 1.25.
