Inventors include Smit, Adrianus Theodorus; Van Zomeren, Andr; Hoek, Michiel; and Bonouvrie, Petronella Adriana.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: The invention relates to an organosolv fractionation process for fractionating lignocellulosic biomass into a biomass pulp and an organosolv liquor comprising a mild fractionation step (a) to remove lignin and hemicellulose comprising contacting the lignocellulosic biomass to the intermediate organosolv liquor originating from step (b) at a temperature in the range of 100 °C – 170 °C and a pH between 1.5 and 3.0, to obtain a mildly treated biomass and the organosolv liquor; and a severe fractionation step (b) to obtain pulp, comprising contacting the mildly treated biomass originating from step (a) with an organosolv treatment liquid at a temperature in the range of 100 °C – 170 °C and a pH below 2.0, to obtain the intermediate organosolv liquor and a biomass pulp. The total fractionation time of steps (a) and (b) is at least 30 min.
