摘要：
A process for purifying a crude ethanol product to reduce formation of byproduct and maximize production of ethanol. The process comprises the step of hydrogenating acetic acid in a reactor in the presence of a catalyst to form the crude ethanol product. The process further comprises the step of separating at least a portion of the crude ethanol product in a purification zone. The purification zone preferably comprises a first column, which yields a first distillate comprising ethanol, water and ethyl acetate, and a first residue comprising acetic acid. The portion of the crude ethanol product has a residence time from the reactor to the purification zone from 5 minutes to 5 days.
摘要（中）：
纯化粗乙醇产物以减少副产物形成并最大限度地生产乙醇的方法。 该方法包括在催化剂存在下在反应器中氢化乙酸以形成粗乙醇产物的步骤。 该方法还包括在纯化区中分离至少一部分粗乙醇产物的步骤。 纯化区优选包括第一柱，其产生包含乙醇，水和乙酸乙酯的第一馏出物和包含乙酸的第一残余物。 粗制乙醇产物的部分从反应器到纯化区的停留时间为5分钟至5天。
