Beschreibung
Zusammenfassung:	The present invention relates to a process for obtaining a bio-crude from biomass, wherein said process comprises the solvothermal liquefaction of biomass in the presence of a solvent mixture until obtaining a gaseous phase, a solid phase, an aqueous liquid phase and an organic liquid phase that comprises the bio-crude. In this invention, said solvent mixture comprises between 0.5% w/w to 99.5% w/w of water and at least one solvent, and said solvent is chosen from alcohols, ketones, aldehydes or precursors thereof under processing conditions. This described process allows the biomass to be used for the production of renewable fuels, as well as for obtaining a bio-crude with an efficiency equal to or greater than 30%, with a calorific value between 20 and 35 MJ/Kg and with a sulphur percentage of less than 1% w/w.
