Abstract

Despite decades of research, Integrated Biorefineries (IBRs) are still not commercially viable because of the long-standing, unresolved challenges related to biomass solids handling and transport (e.g., flowability and fouling), and pretreatment e.g., wettability and conversion). The compendium of challenges facing IBRs lead to operational reliability and time-on-stream estimates of 30%, yet economically viable IBRs require greater than 90% operational reliabilities. The performance of commercial solids handling operations is largely dependent on the fundamental thermodynamic property, surface energy. Combining surface area, thermogravimetric, and inverse gas chromatography analyses, we show the observed differences in surface energy (e.g., wettability and work of cohesion) for anatomically air fractionated corn (Zea mays L.) stover. This study highlights the importance of understanding and tuning biomass surface energy to improve IBR solids handling and transport, and pretreatment operations.
