Acetone organosolv fractionation of beech and birch wood at laboratory-scale results in high sugar yields from the (hemi)cellulose and the isolation of a high purity lignin. In this study, the process is scaled up to validate the technol. at pilot-scale using industrial size beech and birch wood chips and low liquid-to-solid ratios as a next step toward commercialization. Translation of the fractionation process to pilot-scale showed similar performance as compared to the laboratory-scale processing with a good conversion of the wood polymeric pentoses to mostly monomeric sugars and a high delignification. Continuous lignin precipitation by solvent evaporation using the LigniSep process resulted in the formation of nonsticky lignin aggregates with a good filterability. The improved lignin yields and advanced process design as compared to the traditional dilutive lignin precipitation approaches are likely to translate to a better process economy. The pulp washing efficiency and the recovery of (nonprecipitable) lignin from the aqueous hemicellulose stream needs still to be improved for an efficient process design. However, the fractionation performance and high product concentrations in the spent liquor provide an excellent start position for improved process design at com. scale.
