    摘要: The present invention relates to a process for the formation of acetone from acetic acid. The process is conducted at an elevated temperature of above 225° C. by contacting a feed stream containing acetic acid, and an optional carrier gas, with a catalyst. The catalyst comprises a support that is favorable for the production of acetone. The support may comprise titania, zirconia, ceria, silica, iron oxide, and carbon, but preferably is titania, zirconia, and ceria.

    摘要: A hydrogenation catalyst and process using the catalyst for converting a mixture comprising acetic acid and ethyl acetate to ethanol at a first temperature, and the catalyst desorbs ethyl acetate, in the absence of hydrogen, at a second temperature that is greater than the first temperature. The catalyst has a suitable chemisorption of ethyl acetate at the first temperature in the absence of hydrogen. In one embodiment, the first temperature ranges from 125° C. to 350° C. and the second temperature ranges from 300° C. to 600° C. The catalyst comprises one or more active metals or oxide thereof on a support that comprises tungsten or an oxide thereof. The one or more active metals are selected from the group consisting of cobalt, copper, gold, iron, nickel, palladium, platinum, iridium, osmium, rhenium, rhodium, ruthenium, tin, zinc, lanthanum, cerium, manganese, chromium, vanadium, and molybdenum.
