Abstract

See full text

Some variations provide a process for producing cellulosic fructose from biomass, comprising: fractionating a biomass feedstock in the presence of an acid catalyst, a solvent for lignin, and water, to produce a liquor containing cellulose-rich solids, lignin, and dissolved hemicellulose; removing the cellulose-rich solids from the liquor; hydrolyzing the dissolved hemicellulose contained in the liquor, to produce a hydrolyzed liquor comprising hemicellulosic monomers; hydrolyzing the celluloserich solids to produce glucose, using cellulase enzymes or an acid or base hydrolysis catalyst; enzymatically isomerizing the glucose to fructose, using glucose isomerase enzymes; and recovering the fructose in purified form or in a fructose-glucose solution. The cellulosic fructose produced by the disclosed processes has many uses.
