摘要: A method for reducing the mechanical strength of solid biomass material, in particular lignocellulosic biomass, comprises mixing the solid biomass material with an inorganic material and heating the solid biomass material mixture to a toasting temperature in the range of 105° C. to 140° C. during an exposure time of from 1 minute to 12 hours. Before or after the heat treatment, which is referred to as “toasting”, the biomass material mixture is subject to flash heating. The treatment significantly reduces the mechanical energy required for reducing the particle size of the solid biomass material and is suitable as a pretreatment prior to a conversion reaction of the solid biomass material.

摘要: 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.
