Process for extracting ethanol from fermentation broths for direct blending into gasoline while preserving the broth for recycling
Patent
·
OSTI ID:5119451
This patent describes a method of producing gasohol which comprises fermenting ethanol-producing source material in a fermentor, releasing fermentation broth from the fermentor into an extractor, releasing a light alkylate having a boiling range of 50{degrees} - 150{degrees} C into the extractor for countercurrent flow relative to the fermentation broth, flowing the extract from the extractor, blending gasoline with the extract to provide a desired ethanol content in the gasoline, and recycling the extract freed fermentation broth back to the fermentor.
