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 or sugary materials, to produce ethanol and/or butanol, e.g., by fermentation.
Claims29
A method comprising:
- irradiating a cellulosic or lignocellulosic material, while the material is under a pressure above atmospheric pressure, so as to decrease the molecular weight of the cellulosic or lignocellulosic material.
A method comprising:
- irradiating a cellulosic or lignocellulosic material, while the material is under a pressure above atmospheric pressure, with at least 2.5 Mrad of radiation.
