| titleOfInvention | Process for purifying crude ethanol product |
| abstract | In one embodiment, the invention provides a process for purifying a crude ethanol product. The process comprises the step of hydrogenating acetic acid in the presence of a first catalyst in the first reaction zone to form a crude ethanol product comprising ethanol, acetaldehyde, acetic acid, water and acetal. The process also includes the step of separating at least a portion of the crude ethanol product into a refined ethanol stream and by-product stream. The refined ethanol stream comprises ethanol and acetaldehyde; and the by-product stream comprises acetic acid and most of the water from the crude ethanol product. The process also includes the step of hydrolyzing at least a portion of the acetal in the second reaction zone. |
