Dispersing feedstocks and processing materials for saccharification
First Claim
Patent Images
1. A method comprising:
- saccharifying a biomass feedstock in a vessel while mixing with a jet mixer, the biomass feedstock having been dispersed in a liquid medium using a dispersing system that draws the feedstock and liquid medium out of the vessel and recirculates the feedstock and liquid medium back into the vessel,wherein the initial solids concentration of the biomass feedstock dispersed in the liquid medium is at least 20% by weight, and the method further includes adding additional feedstock and saccharifying agent to the vessel during saccharification and dispersing the feedstock in the medium using the dispersing system.

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 ethanol. Biomass feedstock is dispersed in a liquid medium and then saccharified.
