METHODS AND SYSTEMS FOR PROCESSING LIGNIN DURING HYDROTHERMAL DIGESTION OF CELLULOSIC BIOMASS SOLIDS WHILE PRODUCING A MONOHYDRIC ALCOHOL FEED |
摘要 |
<p>Digestion of cellulosic biomass solids may be complicated by release of lignin therefrom. Methods for digesting cellulosic biomass solids may comprise: providing cellulosic biomass solids in the presence of a digestion solvent, molecular hydrogen, and a slurry catalyst capable of activating molecular hydrogen; at least partially converting the cellulosic biomass solids into a phenolics liquid phase comprising lignin, an aqueous phase comprising a glycol derived from the cellulosic biomass solids, and an optional light organics phase; wherein at least a portion of the slurry catalyst accumulates in the phenolics liquid phase as it forms; combining the glycol with the phenolics liquid phase, thereby forming a combined phase; and heating the combined phase in the presence of molecular hydrogen; wherein heating the combined phase reduces the viscosity of the phenolics liquid phase and transforms at least a portion of the glycol into a monohydric alcohol.</p> |
