Processing biomass |
摘要 |
Methods are provided for reducing one or more dimensions of individual pieces of biomass; treating biomass, such as size-reduced biomass; changing a molecular structure of a biomass material; and, optionally, subjecting the biomass to a primary process to form a product. The methods include processing biomass materials using a screw extrusion process, and treating the biomass material with a screw extrusion process in size-reduction and treating steps. |

1. A method of processing biomass materials using a screw extrusion process, the method comprising:
conveying biomass material through a screw extruder comprising a co-extruder having a first barrel and a second barrel, wherein the conveying step comprises conveying a first biomass material through the first barrel and conveying a second biomass material through the second barrel; applying compression and shear forces via a plurality of interpenetrate helicoidal surfaces within the screw extruder, the forces effective to reduce one or more dimensions of individual pieces of biomass material; exposing the biomass material to a plurality of scanning electron beam emitters while conveying the biomass material through the screw extruder, the scanning electron beam emitters each effecting a desired dose of electron beam radiation, wherein the exposing step comprises exposing the first biomass material to a first dose of electron beam irradiation and exposing the second biomass material to a second dose of electron beam irradiation; and producing an extrudate comprising the material discharged from the screw extrusion process. |
