PROCESS FOR PRODUCING HIGH QUALITY BIO-OIL IN HIGH YIELD

摘要

A process is disclosed for converting aparticulate solid biomass material to a high qualitybio-oil in high yield. The process comprises a pre-treatmentstep and a pyrolysis step. The pretreatmentcomprises a step of at least partially demineralizmgthe solid biomass, and improving the accessibility ofthe solid biomass by opening the texture of the particlesof the solid biomass. In a preferred embodimentthe liquid pyrolysis product, is separated, into the bio-oiland an aqueous phase, and the aqueous phase isused, as a solvent in the demineralizatioii step and/orin the step of improving the accessibility of the solidbiomass by opening the texture of the particles of thesolid biomass.
