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 to pre-treat biomass to be used in a biorefinery to produce a fermentation product. The method comprises the steps of preparing the biomass into prepared biomass; and 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 may also comprise a method to pre-treat biomass to be used in a biorefinery to produce a fermentation product. The method comprises the preparing the biomass into prepared biomass; and 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 5 to 15 minutes. The fermentation product can be obtained by separating the pre-treated biomass into a liquid component comprising xylose and a solids component from which glucose can be made available and accessing xylose for fermentation into the fermentation product. A system for pre-treating biomass to be used in a biorefinery to produce a fermentation product may comprise an apparatus to preparing the biomass into prepared biomass; an apparatus for 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 5 to 15 minutes; an apparatus for separating the pre-treated biomass into a liquid component comprising pentose available to be fermented and a solids component comprising cellulose from which hexose can be made available for fermentation and lignin; a fermentation system configured to produce the fermentation product; and a distillation system configured to recover ethanol from the fermentation product. The fermentation product comprises ethanol produced by fermentation of pentose and ethanol produced from the fermentation of hexose. The biomass comprises lignocellulosic material. The lignocellulosic material comprises corn cobs, corn plant husks, corn plant leaves and corn plant stalks.

摘要： Systems and methods for fractionating whole stillage from an ethanol production facility are provided. Whole stillage undergoes a separation of its liquid portion (thin stillage) from the solid portion (fiber cake). In some embodiments, the solids and liquids in whole stillage may be separated utilizing a screening centrifuge. The fiber cake may be dried to generate a high fiber animal feed. The thin stillage may be provided to a three-phase separator for separation into an oil emulsion, an aqueous clarified stillage, and a protein paste. The protein paste may be dried to generate a high protein animal feed with greater than about 45% protein content. The clarified thin stillage is condensed to yield a syrup with greater than around 60% solids. The oil emulsion is subjected to a pH adjustment to liberate the oil from the emulsion, which is then separated.
