PROCESSING MATERIALS

摘要

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 ethanol. Biomass feedstock is saccharified in a vessel by operation of a jet mixer, the vessel also containing a liquid medium and a saccharifying agent.

主权项

1. A method comprising:
placing a liquid medium comprising water and an unsaccharified electron beam irradiated lignocellulosic feedstock in a vessel; saccharifying the electron beam irradiated lignocellulosic feedstock in the vessel, while mixing with a jet mixer comprising a plurality of jet flow agitators, to form a sugar solution, and in the same vessel, converting the sugar solution to a product, utilizing an enzyme and/or a microorganism, wherein the irradiated lignocellulosic feedstock has been irradiated with a dose of at least 10 Mrad.
