ABSTRACT:
A process for the production of ethanol, useful as a fuel, from various cellulose-containing materials by saccharification, fermentation and distillation of the resultant fermented ethanol-containing beer to recover ethanol; which comprises the formation of a slurry of the material being saccharified by recycling a portion of the resultant fermented ethanol-containing beer back to the incoming material being subjected to saccharification whereby the concentration of ethanol during fermentation and subsequent distillation treatment is substantially increased over that utilizing no recycling treatment, the process being carried out at under normal atmospheric conditions.
