Processing biomass and petroleum containing materials

摘要

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.

主权项

1. A method comprising:
processing a cellulosic or lignocellulosic material that has been exposed to an ion beam generated by an accelerator, to produce a product or intermediate; the ion beam providing a radiation dose of greater than 10 Mrad to the cellulosic or lignocellulosic material.
