What is claimed is:
Process for the production of ligno-oligomers comprising the steps of:
a) dissolution of cellulose and hemi-cellulose fraction of biomass making use of an inorganic molten salt hydrate as an inorganic solvent.b) Precipitation of the dissolved (hemi-cellulose and cellulose) by adding an anti-solvent (e.g. H2O and / or an organic anti-solvent).c) Precipitation...
The main advantages of this technology are: Particle Size reduction: From > 1 mm, ±1000-3000p to less than 100p. Enhanced reactivity: Cellulose liquefaction T> 350oC to less than 200oC. Minerals removal: Removal of K, Ca, Fe (catalyst poisons)
