    Abstract: Separation of a product of digestion of cellulosic biomass solids may be challenging due to the various components contained therein. Methods and systems for processing cellulosic biomass, particularly a reaction product of a hydrothermal reaction containing lignin-derived products, such as phenolics, comprise providing the reaction product to a separation zone comprising a liquid-liquid phase separation unit. The liquid-liquid phase separation unit can provide an aqueous portion and a non-aqueous portion, where these portions can be separated into various fractions individually. For example, desirable compounds in the aqueous portion and non-aqueous portion can be recovered from the portions individually and optionally combined to be further processed into a fuels product. Heavier components in the aqueous portion and non-aqueous portion can be recovered from the portions individually and used in the process, such as phenolics that can be used as a digestion solvent.

    Abstract: A process for producing biofuels from biomass is provided by removing sulfur compounds and nitrogen compounds from the biomass by contacting the biomass with a digestive solvent to form a pretreated biomass containing soluble carbohydrates and having less than 35% of the sulfur content and less than 35% of the nitrogen content, based on untreated biomass on a dry mass basis, prior to carrying out aqueous phase reforming and further processing to form a liquid fuel.

    Abstract: A process for the extraction of furfural from a composition comprising furfural, water, at least one organic acid and an oxygenate solvent with a boiling point higher than that of furfural. The process includes: (a) subjecting the composition to a first liquid-liquid separation step to provide: (i) an organic phase; (b) subjecting the organic phase of step (a) to a first distillation step to provide: (i) a first top stream; (c) subjecting the first top stream of step (b) to a second liquid-liquid separation step to provide: (i) a second top stream; and (d) subjecting the second top stream of step (c) to a second distillation step to provide: (i) a third top stream comprising a furfural-water azeotrope, and (ii) a third bottom stream comprising furfural.

    Abstract: Disclosed is a process for the extraction of furfural. The process includes subjecting a composition comprising furfural, water, at least one acid and an aromatic solvent, with a boiling point higher than that of furfural, to a first separation step in a first liquid-liquid separator providing a first organic phase and a first aqueous phase; conveying the first organic phase along a first line to a distillation column and subjecting the first organic phase to a distillation step providing a top stream comprising furfural and a bottom stream comprising the aromatic solvent; subjecting the first aqueous phase and a portion of the bottom stream to a second separation step providing a second organic phase; conveying the second organic phase along a second line which either feeds its contents into the first line or into the distillation column and subjecting the resultant mixture to said distillation step.

    Abstract: Implementations of the disclosed subject matter provide a process for converting biomass into furfural. The process may include subjecting a pentosan-containing biomass material to an acid catalyzed digestion process in a digestion vessel to produce a digested product stream comprising C5-carbohydrates and solids comprising cellulose. The digested product stream may be separated into a liquid product stream and a solid product stream comprising lignin and cellulose. The solids product stream may be contacted with water and an organic solvent, thereby converting at least part of the lignin to a phenolic solvent. The C5-carbohydrate in the liquid product stream may be subjected to a dehydration reaction in the presence of an acid catalyst and a biphasic mixture comprising an aqueous phase and a water-immiscible organic phase, wherein the water-immiscible organic phase includes at least a portion of the phenolic solvent, to produce furfural or a furan derivative.

    Abstract: Methods and processes for the production of valuable organic products and alcohols from biomass material using a closed-loop process having numerous advantages over prior production methods are described. In the process, the biomass is subjected to acid-catalyzed digestion, followed by a separation of the digestion product stream into a solid product stream and a liquid product stream, the liquid product stream thereafter undergoing acid-catalyzed dehydration in the presence of an organic solvent, and thereafter separating the organic products in the organic layer from the aqueous layer. During the process, aqueous and organic fluid streams are fed back into various portions of the production process to increase the concentration of active portions and maximize product recovery.
