PROCESSING BIOMASS
First Claim
Patent Images
1. A method of processing biomass, the method comprising:
- reducing one or more dimensions of individual pieces of biomass;
exposing the biomass to a first dose of electron beam radiation using a scanning electron beam;
conveying the biomass, using a screw; and
exposing the biomass to a second dose of electron beam radiation using a scanning electron beam;
wherein the electron beam radiation from the first dose and the second dose are each provided by a scanning electron beam device operated at a power from 50 kW to 500 kW, and the first dose and the second dose of electron beam radiation are each provided at a dose rate of at least 1 Mrad per second; and
wherein the biomass comprises cellulosic and/or lignocellulosic material.

Abstract
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.
