470328 Optimization of Biomass Processing through Physical Fractionation
Biomass heterogeneity has important impacts on a number of important processing variables. These include differing responses of the biomass to comminution that result in wide particle size distributions, substantial differences in particle hygroscopicity and drainability, a diversity of compositions (including lignin and ash), and a wide range of responses to chemical pretreatments and hydrolysis. This work will, work will assess physical fractionation approaches for corn stover and energy sorghum that mimic industrially relevant fractionations utilizing either manual classification that mimics in-field classification that could be achieved during harvest and combinations of comminution and sieving that could be performed either during harvest or at decentralized processing depots. Employing these approaches in this work, we demonstrate that physical fractionation can yield biomass fractions with diverse properties that include wide ranges for lignin content and hygroscopicity that impact feedstock processability (i.e., response to pretreatment and enzymatic hydrolysis).
