Techno-economic analysis of monosaccharide production via fast pyrolysis of lignocellulose

The economic feasibility of a facility producing monosaccharides, hydrogen and transportation fuels via fast pyrolysis and upgrading pathway was evaluated by modeling a 2000 dry metric ton biomass/day facility using Aspen Plus®. Equipment sizing and cost were based on Aspen Economic Evaluation® software. The results indicate that monosaccharide production capacity could reach 338 metric tons/day. Co-product yields of hydrogen and gasoline were 23.4 and 141 metric tons/day, respectively. The total installed equipment and total capital costs were estimated to be

0.64/kg monosaccharide was calculated. Sensitivity analysis demonstrates that fixed capital cost, feedstock cost, product yields, and product credits have the greatest impacts on facility IRR. Further research is needed to optimize yield of sugar via the proposed process to improve economic feasibility.

Techno-economic analysis of biofuel production considering logistic configurations.

A techno-economic analysis of mild catalytic pyrolysis (CP) of woody biomass followed by upgrading of the partially deoxygenated pyrolysis liquid is performed to assess this pathways economic feasibility for the production of hydrocarbon-based biofuels. The process achieves a fuel yield of 17.7 wt% and an energy conversion of 39%. Deoxygenation of the pyrolysis liquid requires 2.7 wt% hydrogen while saturation of aromatic rings in the pyrolysis liquid increases total hydrogen consumption to 6.4 wt%. Total project investment is

3.69 per gal is estimated assuming 10% internal rate of return. Twenty-nine percent of the capital outlay is the result of including a co-generation system to consume heat generated from burning part of the off-gases from pyrolysis and upgrading and all of the coke during regeneration of catalysts. Forty-five percent of the MFSP arises from the cost of biomass feedstock. Hydrogen required for the upgrading process is generated using the balance of the process off-gases. The analysis reveals that an optimum design would include a cogeneration unit; however using natural gas for hydrogen generation is more favorable than using process off-gases as the feed. An uncertainty analysis indicates a probable fuel price of
