    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.

    摘要： A process for producing ethanol is disclosed, comprising the steps of hydrogenating acetic acid in a reactor in the presence of a catalyst to form a crude ethanol product, separating at least a portion of the crude ethanol product in a column into a first distillate comprising ethanol and a first residue comprising acetic acid and water, wherein a substantial portion of the water in the crude ethanol product that is fed to the column is removed in the first residue, and separating a portion of the ethanol mixture stream to the second distillation column to yield an ethanol product sidedraw, second residue comprising water and a second distillate comprising ethyl acetate. The water content of the ethanol product sidedraw may be further reduced to yield a stream having reduced water content.
