摘要： A system and method for managing an ethanologen for use in biorefinery is disclosed. The method for propagating ethanologen for use in the production of a fermentation product from biomass comprises the steps of providing a medium for propagation of ethanologen; supplying a first cell mass of ethanologen to the medium; supplying xylose to the medium as a carbon source for the ethanologen; and maintaining the medium comprising the first cell mass of ethanologen at a pH of between about 5.0 and 6.0 and at a temperature of between about 26 and About 37 degrees Celsius so that the first cell mass of ethanologen is propagated into a second cell mass of ethanologen. The second cell mass of ethanologen is larger than the first cell mass of ethanologen. The system for propagating ethanologen for use in the production of a fermentation product from biomass comprises a first stage comprising a first vessel configured to maintain a medium comprising ethanologen; a second stage comprising a second vessel configured to maintain a medium supplied from the first stage; a source of xylose to be provided to the medium as a carbon source for ethanologen in the first stage; and a source of xylose to be provided to the medium as a carbon source for the ethanologen in the second stage. The ethanologen has a first cell mass when supplied to the first stage and the ethanologen has a second cell mass when supplied from the first stage to the second stage and the ethanologen has a third cell mass when supplied from the second stage. The second cell mass is at least 200 times larger than the first cell mass The third cell mass is at least 20 times larger than the second cell mass.

The system comprises a method for producing a fermentation product in a fermentation system from biomass that has been pre-treated and separated into a first component and a second component. The method comprises the steps of supplying the first component to the fermentation system; providing an ethanologen to the fermentation system; maintaining the first component and ethanologen in the fermentation system; and recovering the fermentation product from the fermentation system. A fermentation system configured to produce a fermentation product from biomass that has been pre-treated and separated into a first component and a second component is disclosed.

The biorefinery comprises a preparation system to prepare the biomass into prepared biomass; a pre-treatment system to pre-treat the prepared biomass with a dilute acid for separation into a first component from which pentose can accessed for fermentation and a second component from which hexose can be made available for fermentation; a first treatment system to treat the first component into a treated first component by removing removed components from the first component; a first fermentation system to produce a first fermentation product from the pentose; a distillation system to recover ethanol from the first fermentation product; and a treatment system to process removed components. The biomass comprises lignocellulosic material; the lignocellulosic material comprises at least one of corn cobs, corn plant husks, corn plant leaves and corn plant stalks. The first component comprises pentose; the pentose comprises xylose. The ethanologen is capable of fermenting xylose into ethanol.

摘要： The present disclosure relates to a dewatering systems, and related methods, that are adapted to convey lignocellulosic biomass to separate at least a portion of the water from a lignocellulosic biomass slurry and accumulate the dewatered lignocellulosic biomass. The dewatering system also includes a headspace occupied by a gas that is at a pressure that facilitates transferring the accumulated biomas into a pretreatment reactor having a pressurized headspace. Such a dewatering system can prevent undue mixing and backflow of gas (e.g., steam) from the pretreatment reactor.
