PROCESS FOR CATALYTIC HYDROGENATION OF ACETIC ACID FORMING ETHANOL WITH PROMOTED CATALYST ACTIVITY FOR ETHYL ACETATE CONVERSION

摘要

The process of the current invention relates to the production of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid and ethyl acetate in the presence of a catalyst. Conversion of ethyl acetate may be improved by adding water to the reactor. At least 0.01 wt.% water may be added to the reactor. The crude ethanol product is separated in one or more columns to yield an ethanol product.
