System for treatment of biomass to facilitate the production of ethanol
First Claim
1. A system for the production of ethanol from pre-treated biomass comprising:
- a source of pre-treated biomass;
a centrifuge in fluid communication with the source of pre-treated biomass, wherein the centrifuge is configured to separate the pre-treated biomass into a liquid component and a solid component, wherein the liquid component comprises sugars;
a filter comprising a pore size of between 25 microns and 100 microns, wherein the filter is in fluid communication with the centrifuge to receive the liquid component to provide a filtered liquid component;
an apparatus configured to remove one or more inhibitors from the filtered liquid component, thereby yielding a first treated liquid component, wherein the apparatus is in fluid communication with the filter to receive the filtered liquid component;
an evaporation system in fluid communication with the apparatus to receive the first treated liquid component to remove water from the first treated liquid component and produce a second treated liquid component; and
a fermentation system in fluid communication with the evaporation system to receive the second treated liquid component, wherein the fermentation system comprises an ethanologen to ferment the sugars into ethanol;
wherein the apparatus comprises an ion exchange system comprising a resin bed;
wherein the resin bed comprises a resin capable of binding said inhibitors;
wherein the biomass comprises lignocellulosic material;
wherein the lignocellulosic material comprises at least one of corn cobs, corn plant husks, corn plant leaves and corn plant stalks.

Abstract
Systems for treating biomass for the production of ethanol are disclosed. The systems are configured to treat a liquid component separated from biomass to yield sugars available to be fermented into a fermentation product. The systems comprise a filter configured to remove particulate matter to provide a filtered component and an apparatus configured to remove inhibitors from the filtered liquid component provide a treated liquid component comprising sugars available for fermentation. Methods for treating for treating biomass useful in the production of a fermentation product are also disclosed. The methods include the steps of filtering a liquid component to remove particulate matter thereby yielding a filtered liquid component, and treating the filtered liquid component to remove inhibitors thereby yielding a treated liquid component comprising sugars available to be fermented into a fermentation product.
