ABSTRACT:
A process for producing ethanol by the conversion of carbohydrates from a corn dry milling process in which the bottoms fraction from distillation of ethanol in a conventional yeast fermentation is used in a process including a combination of biochemical and synthetic conversions. The process results in high yield ethanol production with concurrent production of high value coproducts. An acetic acid intermediate is produced from bottoms fraction, followed by conversion of the acetic acid into ethanol using esterification and hydrogenation reactions. Coproducts of the process include a high protein content solids fraction produced in the fermentation.
