THF Co-Solvent Biomass Fractionation to Catalytic Fuel Precursors with High Yields (Final Report)

Economics and global warming potential of a commercial-scale delignifying biorefinery based on co-solvent enhanced lignocellulosic fractionation to produce alcohols, sustainable aviation fuels, and co-products from biomass

“…15 Over 90% of the biomass lignin extracted during CELF is precipitated as WIS lignin, otherwise known as CELF lignin. Due to the high purity of each intermediate from CELF pretreatment, favorable conditions have been reported that support downstream biochemical, 16,17 thermochemical, 18,19 and catalytic 20,21 valorization pathways, which are able to harness the possibility of lower-cost operations with higher carbon concentrations and higher lignin quality to improve the carbon efficiency, energy intensity, and capital use fraction of a biorefinery. For these reasons, CELF was chosen as the first processing step in the biorefinery strategy of this study.…”
