process for the production of high quality high-quality bio-oil

摘要

process for the production of high quality bio-oil in high yield. the present invention relates to a process that is disclosed for converting a particulate solid biomass material to a high quality bio oil in high yield. the process comprises a pre-treatment step and a pyrolysis step. the pretreatment comprises a demineralization stage, at least partial, of 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 accessibility. solid biomass by opening the particle texture of the solid biomass.
