    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 method for converting solid biomass into hydrocarbons includes contacting the solid biomass with a catalyst in a first riser operated at a temperature in the range of from about 50° C. to about 200° C. to thereby produce a first biomass-catalyst mixture and a first product comprising hydrocarbons; a) separating the first product from the first biomass-catalyst mixture; c) charging the first biomass-catalyst mixture to a second riser operated at a temperature in the range of from about 200° C. to about 400° C. to thereby produce a second biomass-catalyst mixture and a second product comprising hydrocarbons; d) separating the second product from the second biomass-catalyst mixture; e) charging the second biomass-catalyst mixture to a third riser operated at a temperature greater than about 450° C. to thereby produce a spent catalyst and a third product comprising hydrocarbons; and f) separating the third effluent from the spent catalyst.
