Abstract
The liquefaction of biomass is discussed in this paper from the perspective of processing wood-solvent suspensions. The particular rheology of these systems, the need for solvation and the treatment of suspensions in the 10 to 30% initial solids content has led to the development of a methodology which involves thermomechanical pretreatment as a key step of the overall liquefaction process. Configuration of the pretreatment loops and their influence on defibration and solvation will be presented and discussed relative to their effects on liquefaction.
