Systems and methods that include starch derived from grain as a carbon source for propagation of microorganisms.

Methods and systems for starch based propagation of a microorganism

The present disclosure relates to methods and systems of fermenting that include, after the fermentable composition has been exposed to fermentations conditions to produce biochemical, exposing at least a portion of a fermentable composition to a disruption process to disrupt at least a portion of insoluble solid component. After the fermentable composition has been exposed to a disruption process, the fermentable composition can be exposed to fermentation conditions again to product biochemical.

Methods of subjecting biomass solids to at least one disruption process after the biomass solids have been exposed to at least fermentation, and related systems

The present disclosure includes systems and methods for hydrolyzing (e.g., pretreatment and/or enzymatic hydrolysis) lignocellulosic biomass into one or more sugars such as pentose and glucose sugars. The present disclosure includes configurations that incorporate flashing and/or liquid cooling so as to permit desirable throughput. The present disclosure also includes a liquefaction configuration so as to permit desirable (e.g., continuous high volume) throughput.

Systems and methods for processing lignocellulosic biomass

The present disclosure includes methods and systems for removing one or more fermentation inhibitors (e.g., furfural) from a hydrolysate composition (e.g., a whole broth hydrolysate) by gas stripping the one or more fermentation inhibitors from the hydrolysate composition.

Methods of removing one or more compounds from a lignocellulosic hydrolysate via gas stripping, and related systems

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.

Systems and methods for dewatering a slurry that includes lignocellulosic biomass and liquid

A system for treating biomass for the production of ethanol is disclosed. A biorefinery for producing a fermentation product from biomass is disclosed. The biorefinery comprises a system for preparing the biomass into prepared biomass and a system for pre-treating the biomass into pre-treated biomass. The biorefinery comprises a separator, a first treatment system, a second treatment system, and a fermentation system. A method for producing a fermentation product from biomass is disclosed.

System for the treatment of biomass

The present invention relates to methods and systems for remediating one or more impurities (e.g., diacetyl) that are present in manufacturing an alcohol (e.g., ethanol) from cellulosic biomass. The methods and systems include reacting the one or more impurities with at least one treatment compound (e.g., an oxidizing agent, an alkali compound, or a mixture thereof) to form a reaction product that can be separated from the alcohol.

Methods and systems for reducing the level of one or more impurities that are present in a pretreated cellulosic material and/or distillate

The present disclosure includes embodiments of methods and systems for reducing the size of lignocellulosic feedstock. The present disclosure also includes embodiments of methods and systems for separating oversized, in process lignocellulosic material, reducing the size of the oversized lignocellulosic material offline, and the reintroducing the lignocellulosic material back into the main process flow after size reduction.

Methods of reducing the size of lignocellulosic material, and related systems

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).

Method for treatment of biomass

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 and supplying a first cell mass of ethanologen to the medium. A first cell mass of ethanologen is propagated into a larger second cell mass of ethanologen.

System for management of yeast to facilitate the production of ethanol

A system for pre-treating biomass for the production of ethanol is provided. The system supplies biomass to a steaming bin, wherein the biomass is mixed with water, and inputting the steamed biomass to a first pretreatment reactor, wherein the steamed biomass comprises liquids and solids. The system removes a bulk of liquids from the solids and feeding the solids into a second pretreatment reactor. The system applies a pressure drop to the solids in the second pretreatment reactor, wherein the pressure drop opens up a structure of the solids, and sending the solids to a fermentation process for ethanol processing.

Biomass pretreatment

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.
