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: Digestion of cellulosic biomass solids may be complicated by release of lignin therefrom. Methods and systems for processing a reaction product containing lignin-derived products, such as phenolics, can comprise hydrotreating the reaction product to convert the lignin-derived products to desired higher molecular weight compounds. The methods can further include separating the higher molecular weight compounds from unconverted products, such as unconverted phenolics, and recycling the unconverted phenolics for use as at least a portion of the digestion solvent and for further conversion to desired higher molecular weight compounds with additional hydrotreatment.

Abstract: A selective removal of metal and its anion species that are detrimental to subsequent hydrothermal hydrocatalytic conversion from the biomass feed prior to carrying out catalytic hydrogenation/hydrogenolysis/hydrodeoxygenation of the biomass in a manner that does not reduce the effectiveness of the hydrothermal hydrocatalytic treatment while minimizing the amount of water used in the process is provided.

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 extraction unit. The liquid-liquid extraction 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 the production of furfural from a biphasic composition including furfural, an organic solvent and soluble organic debris. The said process includes subjecting the biphasic composition to a liquid-liquid separation step to provide an organic phase and an aqueous phase. The organic phase includes the organic solvent, a first portion of the furfural and a first portion of soluble organic debris. The aqueous phase includes a remainder portion of the furfural and a remainder portion of soluble organic debris. The organic phase is subjected to a distillation step to provide a furfural stream and an organic solvent stream including the organic solvent and the first portion of the soluble organic debris. The organic solvent stream is conveyed to an adsorption unit to adsorb a second portion of the soluble organic debris, forming an organic debris-depleted recycle stream.
