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) by adding an anti-solvent (e.g. H2O and / or an organic anti-solvent).c) Precipitation on Lignin...
The main advantages of this technology are:
Particle Size reduction: From > 1 mm, ±1000-3000µ to less than 100µ.Enhanced reactivity: Cellulose liquefaction T> 350°C to less than 200°C.Minerals removal: Removal of K, Ca, Fe (Catalyst poisons)
