Abstract
There is described a method of processing biomass which comprises the steps of: (i) processing biomass material in an aqueous system in the presence of an oxalic acid catalyst to produce a slurry; (ii) subjecting the slurry to an acidified organosolv liquor and optionally de-aerating the resulting mixture before exposing the mixture to ultrasound in a pretreatment step; and (iii) completing the fractionation process using thermal digestion, followed by separation of the constituents into lignin, hemi-cellulose (monosaccharides) and cellulose with the addition of water.
