Abstract: Biomass compaction during hydrothermal digestion of cellulosic biomass solids may become problematic, particularly as the vertical height of a cellulosic biomass charge increases. Compaction may be decreased in a horizontally configured hydrothermal digestion unit. Methods for digesting cellulosic biomass solids may comprise: providing a hydrothermal digestion unit having a length or a width greater than its height and containing a fluid phase digestion medium and a slurry catalyst capable of activating molecular hydrogen; introducing cellulosic biomass solids to the hydrothermal digestion unit; distributing the cellulosic biomass solids laterally within the hydrothermal digestion unit; after or while the cellulosic biomass solids are being distributed, supplying an upwardly directed flow of molecular hydrogen through the cellulosic biomass solids and the fluid phase digestion medium; and heating the cellulosic biomass solids in the presence of the slurry catalyst and the molecular hydrogen, thereby forming an alcoholic component derived from the cellulosic biomass solids.

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.
