TLDR
This work proposes a biomass conversion strategy that maximizes the conversion of lignocellulosic biomass into high-value products that can be commercialized, providing the opportunity for successful translation to an economically viable commercial process.Abstract:
The production of renewable chemicals and biofuels must be cost- and performance- competitive with petroleum-derived equivalents to be widely accepted by markets and society We propose a biomass conversion strategy that maximizes the conversion of lignocellulosic biomass (up to 80% of the biomass to useful products) into high-value products that can be commercialized, providing the opportunity for successful translation to an economically viable commercial process Our fractionation method preserves the value of all three primary components: (i) cellulose, which is converted into dissolving pulp for fibers and chemicals production; (ii) hemicellulose, which is converted into furfural (a building block chemical); and (iii) lignin, which is converted into carbon products (carbon foam, fibers, or battery anodes), together producing revenues of more than $500 per dry metric ton of biomass Once de-risked, our technology can be extended to produce other renewable chemicals and biofuelsread more

Improving the production of maleic acid from biomass: TS-1 catalysed aqueous phase oxidation of furfural in the presence of γ-valerolactone
Y. Rodenas,Rafael Mariscal,J.L.G. Fierro,D. Martín Alonso,James A. Dumesic,M. López Granados +5 more
TL;DR: In this paper, the authors demonstrate that GVL, a renewable solvent, allows not only the production of furfural from biomass at high yield, but also its direct upgrading to valuable maleic acid (MAc) using H2O2 as the oxidant and TS-1 as the catalyst.

Carbohydrate stabilization extends the kinetic limits of chemical polysaccharide depolymerization
TL;DR: A reversible stabilization of xylose and glucose by acetal formation with formaldehyde is used to alter this kinetic paradigm, preventing sugar dehydration to furans and their subsequent degradation, and enables the recovery of biomass-derived carbohydrates in high yields and concentrations.
