Abstract: Processing of a reaction product mixture containing at least one volatile organic compound as well as lignin, lignin derived compounds, and/or unextracted cellulose and hemicellulose using a recovery system comprising at least two flashers or at least one flasher and at least two reboilers. In a particular embodiment, the reaction product mixture comes from reactions involving deconstruction (or digestion) of biomass, particularly cellulosic biomass which contains various polysaccharides (e.g., carbohydrates) and lignin.

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 and systems 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. The methods and systems can further include a further hydrotreatment step configured for additional lignin conversion and/or a further hydrotreatment step configured for generating hydrogen.

Abstract: Processing of a reaction product mixture of cellulosic biomass material containing at least one volatile organic compound at least one of lignin, a lignin-derived compound, unextracted cellulose, unextracted hemicellulose, a caramelan, and any combination thereof by vaporizing the at least one volatile organic compound using at least thermal energy generated by combusting at least a portion of the reaction product mixture. In a particular embodiment, the reaction product mixture comes from reactions involving deconstruction (or digestion) of cellulosic biomass which contains various polysaccharides (e.g., carbohydrates) and lignin.

Abstract: A bottom fraction of a product of a hydrocatalytic reaction is gasified to generate hydrogen for use in further hydrocatalytic reactions. In one embodiment, one or more volatile organic compounds is also vaporized using heat generated in the gasification process. In one embodiment, an overhead fraction of the hydrocatalytic reaction is further processed to generate higher molecular weight compounds. In another embodiment, a product of the further processing is separated into a bottom fraction and an overhead fraction, where the bottom fraction is also gasified to generate hydrogen for use in further hydrocatalytic reactions.
