ABSTRACT:
Biomass slurry is hydrolzyed in a fuel fired hydrolysis heater. When the biomass is fruit waste, the organic acid in the waste is used as the hydrolysis catalyst. When the biomass does not contain organic acid, carbon dioxide generated in a fermenter is fed to the hydrolysis heater as carbonic acid to provide the catalyst. Solids are separated from the hydrolyzed effluent, the flue gas from the hydrolysis heater is used to dry same. The effluent is fermented and subsequently distilled at substantially atmospheric pressure to produce ethyl alcohol vapor. The vapor is fed to a vacuum distillation tower for producing anhydrous ethyl alcohol. Vacuum distillation tower bottoms provide the reflux for the atmospheric distillation unit. A portion of the stillage from the atmospheric distillation unit is recycled by mixing with new feedstock. The remaining stillage is evaporated to a syrup, mixed with unreacted solids, and dried to produce an animal feed byproduct.
