Method for producing hydrocarbons and oxygen-containing compounds, from biomass

摘要

Intensifying fermentation of carbohydrate substrate comprises preparation of aqueous carbohydrate substrate with carbohydrate (2-20%), fermenting substrate to 1-5C alcohols, glycerin, acetaldehyde, acetic acid, and acetone (1.5-10%), and separating desired products from the fermentation medium. The carbohydrate comprises source of nitrogen. Intensifying fermentation of carbohydrate substrate comprises preparation of aqueous carbohydrate substrate with carbohydrate (2-20%), fermenting substrate to 1-5C alcohols, glycerin, acetaldehyde, acetic acid, and acetone (1.5-10%), and separating desired production from the fermentation medium. The carbohydrate comprises source of nitrogen. The amino acids leucine, isoleucine, and/or valine are added to the aqueous carbohydrate substrate as the source of nitrogen to provide amino nitrogen in carbohydrate substrate of 120-420 mg/L.
