L+SScF 232 ABSTRACT 1 A techno-economic analysis was conducted for a simplified lignocellulosic ethanol 2 production process developed and proven by the University of Florida at laboratory, pilot, and 3 demonstration scales. Data obtained from all three scales of development were used with 4 Aspen Plus to create models for an experimentally-proven base-case and 5 hypothetical 5 scenarios. The model input parameters that differed among the hypothetical scenarios were 6 time of L+SScF, enzyme loading, enzymatic conversion, solids loading, and overall process 7 yield. The minimum ethanol selling price (MESP) varied between 50.38 and 62.72 US 8 cents/L. The feedstock and the capital cost were the main contributors to the production cost, 9 comprising between 23-28% and 40-49% of the MESP, respectively. A sensitivity analysis 10 showed that overall ethanol yield had the greatest effect on the MESP. These findings suggest 11 that future efforts to increase the economic feasibility of a cellulosic ethanol process should 12 focus on optimization for highest ethanol yield.

The extent of graphitization is an overlooked limitation to lignin-derived carbon fiber development.

A simple, scalable, and relatively green alternative method for producing graphite anode material for lithium-ion batteries is developed and demonstrated. A low-cost, earth abundant iron powder is used to catalyze...
