Abstract:
In one embodiment, the invention is to a process for producing ethanol, comprising the step of providing from a distillation column in a carbonylation process a purified acetic acid stream comprising up to 25 wt. % water. The process further comprises the step of hydrogenating acetic acid of the purified acetic acid stream in the presence of a catalyst and under conditions effective to form a crude ethanol product comprising ethanol and water. Ethanol is recovered from the crude ethanol product.
