“…Li et al [98] reported that levoglucosan concentration up to 12.7 wt.% could be extracted from bio-oil obtained from loblolly pine wood particles using a water to bio-oil ratio of 1.3:1 at 25 °C and 20 min shaking in a water bath shaker. In a more recent study by Zheng et al [199] recovered an aqueous fraction containing 4.1 wt.% of levoglucosan with the addition of water to bio-oil in a 1:1 ratio at 50 °C and 20 min contact time. These findings suggest that phase separation behavior of bio-oil depends on the type of biomass material used for the production of bio-oil as well as the ratio of water to bio-oil, temperature, and contact time.…”

This review highlights the potential of the pyrolysis-based biofuels production, bio-ethanol in particular, and lipid in general as an alternative and sustainable solution for the rising environmental concerns and rapidly depleting natural fuel resources. Levoglucosan (1,6-anhydrous-β-D-glucopyranose) is the major anhydrosugar compound resulting from the degradation of cellulose during the fast pyrolysis process of biomass and thus the most attractive fermentation substrate in the bio-oil. The challenges for pyrolysis-based biorefineries are the inefficient detoxification strategies, and the lack of naturally available efficient and suitable fermentation organisms that could ferment the levoglucosan directly into bio-ethanol. In case of indirect fermentation, acid hydrolysis is used to convert levoglucosan into glucose and subsequently to ethanol and lipids via fermentation biocatalysts, however the presence of fermentation inhibitors poses a big hurdle to successful fermentation relative to pure glucose. Among the detoxification strategies studied so far, over-liming, extraction with solvents like (n-butanol, ethyl acetate), and activated carbon seem very promising, but still further research is required for the optimization of existing detoxification strategies as well as developing new ones. In order to make the pyrolysis-based biofuel production a more efficient as well as cost-effective process, direct fermentation of pyrolysis oil-associated fermentable sugars, especially levoglucosan is highlly desirable. This can be achieved either by expanding the search to identify naturally available direct levoglusoan utilizers or modify the existing fermentation biocatalysts (yeasts and bacteria) with direct levoglucosan pathway coupled with tolerance engineering could significantly improve the overall performance of these microorganisms.

“…This methodology fails to account for the magnitude, frequency, and compound nature of factor variation that is likely to be encountered by a commercial-scale thermochemical cellulosic biorefinery. Some recent TEAs have included uncertainty analyses of the pathways considered in the form of Monte Carlo simulations or Latin Hypercube Sampling as a means of quantifying the impact of simultaneous factor changes on the TEA result (Thilakaratne et al, 2014;Zhang et al, 2013;Zhu et al, 2014). While superior to a sensitivity analysis, most of these uncertainty analyses employ factor probability distributions that are chosen arbitrarily.…”

“…First, with the exception of the MFSPs that exceed $5/gge ($1.32/lge), it is difficult to determine how successful the pathways will be in the face of volatile petroleum prices. Of the results presented in Table 2 only one (Zhang et al, 2013) uses projected commodity prices to calculate a long-term IRR. Second, the MFSPs are highly sensitive to analytical assumptions.…”

“…The updated analysis calculates a much higher TPI of $429 million (driven in part by the inclusion of splitting and blending stages) for a 2000 MTPD stover FPH facility utilizing an external hydrogen source, which translates into a MFSP of $2.57/gge ($0.68/lge). Zhang et al (2013) uses Aspen Plus to consider a 2000 MTPD FPH biorefinery employing a novel red oak feedstock pretreatment process that produces high yields of levoglucosan, an anhydrosugar derived from cellulose. The levoglucosan is hydrolyzed to glucose while pyrolytic lignin is hydroprocessed to gasoline and diesel using hydrogen produced on-site by steam reforming the aqueous phase of bio-oil.…”

“…NPV is most appropriate for comparisons of mutually exclusive projects for which capital costs vary (Couper, 2003;Park, 2011). However, IRR is widely used in the literature for reporting the results of techno-economic analyses Haro et al, 2013;Piccolo and Bezzo, 2009;Zhang et al, 2013), so it is also calculated here.…”

This analysis identifies the sensitivity of the fast pyrolysis and hydroprocessing pathway to facility location. The economic feasibility of a 2000 metric ton per day fast pyrolysis and hydroprocessing biorefinery is quantified based on 30 different state-specific facility locations within the United States. We calculate the 20-year internal rate of return (IRR) and net present value (NPV) for each location scenario as a function of state-and region-specific factors. This analysis demonstrates that biorefinery IRR and NPV are very sensitive to bio-oil yield, feedstock cost, location capital cost factor, and transportation fuel market value. The IRRs and NPVs generated for each scenario vary widely as a result, ranging from a low of 7.4% and -$79.5 million in Illinois to a high of 17.2% and $165.5 million in Georgia. The results indicate that the economic feasibility of the fast pyrolysis and hydroprocessing pathway is strongly influenced by facility location within the United States. This result could have important implications for cellulosic biofuel commercialization under the revised Renewable Fuel Standard.
