以醋酸为原料直接加氢与酯化加氢制乙醇可解决我国乙醇供给不足的现状，同时可缓减我国醋酸产能过剩的局面。本文从技术与经济的角度对两种工艺进行了分析比较，结果表明，两种工艺在现有条件下均具有可行性，适用于当前的醋酸企业。采用醋酸制乙醇工艺不仅增加装置使用的灵活性，还提高了产品的附加值。
以醋痠為原料直接加氫與酯化加氫製乙醇可解決我國乙醇供給不足的現狀，同時可緩減我國醋痠產能過剩的跼麵。本文從技術與經濟的角度對兩種工藝進行瞭分析比較，結果錶明，兩種工藝在現有條件下均具有可行性，適用于噹前的醋痠企業。採用醋痠製乙醇工藝不僅增加裝置使用的靈活性，還提高瞭產品的附加值。

The present situation of the short supply of ethanol could be resolved by direct hydrogenation and esterification hydrogenation for preparation of ethanol, using acetic acid as raw material, while the complexion of acetic acid overcapacity also could be relieved. These two routings were analyzed and compared from technical and economic aspects in this text, respectively, and the results show that under the existing conditions both are feasible and suitable for current acetic acid enterprises. The flexibility in use of devices could not only be increased, but also the product added value would be improved by adopting ethanol preparation routing from acetic acid.
