    摘要： In one embodiment, the invention is to a process for producing ethanol. The process comprises the step of hydrogenating an acetic acid feed stream in a first reactor to form a crude ethanol product. The crude ethanol product may comprise, among other components, ethanol, acetaldehyde, and residual acetic acid. The process further comprises the step of recovering acetaldehyde from the crude ethanol product. The process further comprises the steps of feeding a first portion of the recovered acetaldehyde to the first reactor and reacting the first portion of the recovered acetaldehyde in the first reactor to form additional ethanol. In addition, the inventive process may comprise the steps of feeding a second portion of the recovered acetaldehyde to a second reactor and reacting the second portion of the recovered acetaldehyde in the second reactor to form an additional product.

    摘要翻译： 在一个实施方案中，本发明涉及一种生产乙醇的方法。 该方法包括在第一反应器中氢化乙酸进料流以形成粗乙醇产物的步骤。 粗乙醇产物可以包括乙醇，乙醛和残余乙酸等组分。 该方法还包括从粗乙醇产物中回收乙醛的步骤。 该方法还包括以下步骤：将回收的乙醛的第一部分进料到第一反应器中，并使第一部分回收的乙醛在第一反应器中反应形成另外的乙醇。 此外，本发明的方法可以包括将第二部分回收的乙醛进料到第二反应器并使第二部分回收的乙醛在第二反应器中反应以形成另外的产物的步骤。

    摘要： In one embodiment, the present invention is to a process for producing a anhydrous ethanol composition comprising hydrogenating acetic acid in the presence of a catalyst to form a crude ethanol product; separating in a first column at least a portion of the crude ethanol product into a first distillate comprising ethanol, water and ethyl acetate, and a first residue comprising acetic acid; separating in a second column at least a portion of the first distillate into a second distillate comprising ethyl acetate and a second residue comprising ethanol and water; separating in a third column at least a portion of the second residue into a third distillate comprising ethanol and residual water and a third residue comprising separated water; and dehydrating at least a portion of the third distillate to form the anhydrous ethanol composition. The anhydrous ethanol composition, as formed, comprises less than 1 wt. % water, based on the total weight of the anhydrous ethanol composition.
