Life-cycle assessment and techno-economic analysis of the utilization of bio-oil components for the production of three chemicals

摘要: Bio-based chemicals have gained more widespread attention than bio-fuels because of the decline in crude oil prices. The development technologies to produce from bio-oil is potentially attractive simplicity preparation. This study presents a prospective and detailed techno-economic life-cycle assessment for joint production levoglucosan, phenol-formaldehyde resins, noncorrosive road deicers using fast biomass pyrolysis, fractions, purification pathway by modeling 60-dry-metric-ton per day facility. In particular, environmental metrics (i.e., global warming potential 100a, cumulative energy demand, eco-indicator 99) as well 20-year facility internal rate return (IRR) are determined, uncertainty analysis performed provide deeper insight into effect these model parameters reliability predictions. It found that (BO)-derived levoglucosan was fairly environmentally competitive, BO-resin promising under aspects, BO-deicer possessed poor profiles. On basis inventory this study, two slightly universal conclusions could be further proved: (1) if consumption chemical auxiliaries provided nonrenewable resources too large biomass-based process, process achieve higher impacts compared with conventional resources, (2) an increase product yields effectively reduce footprint process. For biorefinery IRR 29.6%. GWP100a (22.3 kgCO2-eq kg−1), CED (484 MJeq kg−1) EI-99 (1.91 points kg) values much BO-LG (2.19 kg−1, 29.7 kg−1 0.151 (0.934 32.7 0.134 kg). results showed project commercially attractive, economic environment low risk investment.
