Abstract

See full text

A method for treating fermented lignocellulosic biomass to be supplied to a distillation system for production of ethanol is provided. The method includes pre-treating lignocellulosic biomass into pre-treated biomass and separating the pre-treated biomass into a liquid component comprising sugars and a solids component comprising cellulose and lignin. The method also includes hydrolysing the solids component of the pre-treated biomass into a hydrolysed biomass comprising sugars and lignin and fermenting the hydrolysed solids component of the pre-treated biomass into a fermentation product comprising ethanol and lignin. The method also includes treating the fermentation product and distilling the treated fermentation product to recover the ethanol. The lignocellulosic biomass comprises cellulose, hemi-cellulose and lignin.
