摘要：
The present invention is directed to the separation of ethanol from a crude ethanol product obtained from the vaporization and hydrogenation of acetic acid using reduced residence time for the vapor phase reactants between exiting the vaporizer and entering the reactor. The crude ethanol product is separated in at least one column to recover an ethanol product.
