本发明涉及在催化剂的存在下,由乙酸和乙酸乙酯加氢生产粗乙醇。通过将水添加到反应器中可能提高乙酸乙酯的转化率。至少0.01wt%水可加入到反应器中,粗乙醇需要经过一个或多个塔进行分离,得到乙醇产物。
The present invention relates to the production of crude ethanol from the hydrogenation of acetic acid and ethyl acetate in the presence of a catalyst. The conversion of ethyl acetate may be increased by adding water to the reactor. At least 0.01 wt% water may be added to the reactor, and the crude ethanol may need to be separated via one or more columns to yield the ethanol product.
