摘要： A system for the pre-treatment of biomass for use in a biorefinery to produce ethanol and other bioproducts is disclosed. The system comprises a method comprising the steps of preparing the biomass into prepared biomass; pre-treating the prepared biomass into pre-treated biomass by application of a dilute acid having a concentration of about 0.8 to 1.1 percent by weight at a temperature of about 130 to about 170 degrees Celsius for a period of time in a range of about 8 to 12 minutes. The system also comprises an apparatus for separating the pre-treated biomass into a liquid component comprising pentose and a solids component comprising cellulose and lignin; a fermentation system configured to produce the fermentation product; and a distillation system. The fermentation product comprises ethanol. The biomass comprises lignocellulosic material, comprising corn cobs, corn plant husks, corn plant leaves and corn plant stalks.

摘要： 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.

摘要： The subject disclosure relates to a method for producing a fermentation product from biomass that has been pre-treated in a pre-treatment system and separated into a liquid component and a first solids component. The method comprises: (a) treating the liquid component in a filtration system comprising at least one nano-filter to produce a treated liquid component, and to remove an acid from the liquid component; (b) supplying the treated liquid component, a fermenting organism, and agents to a fermentation system; (c) recovering the fermentation product from the fermentation system; and (d) supplying the acid for re-use in the pre-treatment system. In many embodiments, the biomass comprises lignocellulosic material and the liquid component comprises pentose (e.g., xylose).
