Abstract
Biomass feedstocks (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful products, such as fuels. For example, systems are described that can convert feedstock materials to a sugar solution, which can then be fermented to produce a product such as a biofuel.
Claims22
A method to process lignocellulosic material, the method comprising:
- irradiating the lignocellulosic material to produce irradiated lignocellulosic material having reduced recalcitrance;
- and
- wet milling the irradiated lignocellulosic material in a vessel while applying a jet mixer to the irradiated lignocellulosic material, using a wet milling system comprising one or more jet mixers and one or more wet mills, wherein one or more jet heads and one or more wet milling heads are disposed in a tank containing a fluid having the irradiated lignocellulosic material dispersed therein.
