Abstract

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful products, such as fuels. For example, systems can use feedstock materials, such as cellulosic and/or lignocellulosic materials and/or starchy materials, to produce ethanol and/or butanol, e.g., by fermentation.

Claims

1. A method comprising:

saccharifying an irradiated cellulosic or lignocellulosic material,

the irradiated cellulosic or lignocellulosic material having been produced by exposing a cellulosic or lignocellulosic material to a plurality of electrons that have been accelerated by a continuous wave electron beam device to provide a radiation dose of greater than 10 Mrad to the cellulosic or lignocellulosic material, wherein the radiation dose is provided at a dose rate of about 1 Mrad/s to about 10 Mrad/s.

2. The method of claim 1, wherein the cellulosic or lignocellulosic material is saccharified utilizing an enzyme.

3. The method of claim 1 wherein the continuous wave device has an output power of at least 50 kW.
