A process is disclosed for converting a particulate solid biomass material to a high quality bio-oil in high yield. The process comprises a pretreatment step and a pyrolysis step. The pretreatment comprises a step of at least partially demineralizing the solid biomass, and improving the accessibility of the solid biomass by opening the texture of the particles of the solid biomass. In a preferred embodiment the liquid pyrolysis product is separated into the bio-oil and an aqueous phase, and the aqueous phase is used as a solvent in the demineralization step and/or in the step of improving the accessibility of the solid biomass by opening the texture of the particles of the solid biomass.

Disclosed is a method for heating a biomass moving along an industrial treatment line including an inlet (1) for the incoming biomass, a heating unit (4), and a treatment station (5). A fraction of the biomass heated by the heating unit (4) is returned along a return branch (R) to a mixing station (2) upstream of the heating unit (4) so as to form, together with the incoming biomass, a mixture having a temperature above the temperature of the incoming biomass, the heated biomass fraction being removed at an outlet (51) of the treatment station (5).
