    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: The present invention, in one embodiment, relates to a process for producing ethanol. The process comprises the step of reacting acetic acid and hydrogen in a shell and tube reactor and in the presence of a catalyst under conditions effective to form a crude ethanol product. The crude ethanol product comprises ethanol, acetic acid, ethyl acetate, and water. The process further comprises the step of recovering ethanol from the crude ethanol product. The shell and tube reactor comprises one or more tubes, each containing a heat transfer medium, and a shell comprising the catalyst. Preferably, the shell and tube reactor has an inlet temperature and an outlet temperature and the inlet temperature is substantially similar to or less than the outlet temperature.
