Abstract: Maintaining long residence times during hydrothermal digestion of cellulosic biomass solids may be complicated by a number of factors, including biomass compaction. Advantages in this regard may be realized by digesting cellulosic biomass solids in an inclined digestion unit. Such methods can comprise: introducing cellulosic biomass solids to a hydrothermal digestion unit comprising one or more inclined surfaces therein; introducing a fluid phase digestion medium containing a slurry catalyst to the hydrothermal digestion unit, the slurry catalyst being capable of activating molecular hydrogen; supplying an upwardly directed flow of molecular hydrogen from a source disposed along each inclined surface as the cellulosic biomass solids descend along each inclined surface; and heating the cellulosic biomass solids as they descend along each inclined surface in the presence of the slurry catalyst and the molecular hydrogen, thereby forming an alcoholic component derived from the cellulosic biomass solids.

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: 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.
