Controlling lignin solubility and hydrogenolysis selectivity by acetal-mediated functionalization

Jeremy Luterbacher, Anastasiia Komarova, Graham Reid Dick

Existing lignocellulosic biomass fractionation processes produce lignin with random, interunit C-C bonds that inhibit its depolymerization and constrain its use. Here, we exploit the aldehyde stabilization of lignin to tailor its structure, functionality, ...

Guidelines for performing lignin-first biorefining

Jeremy Luterbacher, Feng Wang

The valorisation of the plant biopolymer lignin is now recognised as essential to enabling the economic viability of the lignocellulosic biorefining industry. In this context, the "lignin-first" biorefining approach, in which lignin valorisation is conside ...

Techno-economic analysis and life cycle assessment of a biorefinery utilizing reductive catalytic fractionation

Jeremy Luterbacher

Reductive catalytic fractionation (RCF) is a promising approach to fractionate lignocellulose and convert lignin to a narrow product slate. To guide research towards commercialization, cost and sustainability must be considered. Here we report a techno-eco ...

Lignin First: Confirming the Role of the Metal Catalyst in Reductive Fractionation

Paul Joseph Dyson, Gabor Laurenczy, Zhaofu Fei, Antoine Philippe Van Muyden, Lu Chen, Ning Yan, Xinjiang Cui

Rhodium nanoparticles embedded on the interior of hollow porous carbon nanospheres, able to sieve monomers from polymers, were used to confirm the precise role of metal catalysts in the reductive catalytic fractionation of lignin. The study provides clear ...

Aldehyde-Assisted Lignocellulose Fractionation Provides Unique Lignin Oligomers for the Design of Tunable Polyurethane Bioresins

Jeremy Luterbacher, Jean Thierry C Behaghel de Bueren, Florent Emmanuel Héroguel, Raymond Gérard Buser, Chloé Wegmann

Thanks to chemical stabilization, aldehyde-assisted fractionation (AAF) of lignocellulosic biomass has recently emerged as a powerful tool for the production of largely uncondensed lignin. Depolymerization of AAF lignin via ether deavage provides aromatic ...

Lignin Functionalization for the Production of Novel Materials

Jeremy Luterbacher, Stefania Bertella

Lignin, a major constituent of lignocellulosic biomass, is the largest natural source of aromatic molecules and thus is an attractive feedstock for renewable chemical production. Direct incorporation of isolated lignin into materials has long been research ...

Selective hydrogenation of lignin-derived compounds under mild conditions

Paul Joseph Dyson, Gabor Laurenczy, Antoine Philippe Van Muyden, Lu Chen, Xinjiang Cui

A key challenge in the production of lignin-derived chemicals is to reduce the energy intensive processes used in their production. Here, we show that well-defined Rh nanoparticles dispersed in sub-micrometer size carbon hollow spheres, are able to hydroge ...

Mechanistic Study of Diaryl Ether Bond Cleavage during Palladium-Catalyzed Lignin Hydrogenolysis

Jeremy Luterbacher, Yuan Li

Hydrogenolysis has emerged as one of the most effective means of converting polymeric lignin into monoaromatic fragments of value. Reported yields may be higher than for other methods and can exceed the theoretical yields estimated from measures of the con ...

Aldehyde-Assisted Fractionation Enhances Lignin Valorization in Endocarp Waste Biomass

Jeremy Luterbacher, Jean Thierry C Behaghel de Bueren, Florent Emmanuel Héroguel, Graham Reid Dick, Raymond Gérard Buser, Chloé Wegmann

Endocarp biomass, which forms much of the inedible portion of nuts and stone fruits, is a promising feedstock for aromatic chemical production due to its high lignin content and because it is a food industry waste. Here, we tested the nut shells and fruit ...
