Selective Production of Syringaldehyde and Vanillin from Acetal-Stabilized Lignin

Jeremy Luterbacher, Jean Thierry C Behaghel de Bueren, Wu Lan

Industrial lignin oxidation has been used for vanillin production but is largely uncontrolled, not fully understood mechanistically, and leads to low yield. Here, we have demonstrated high-efficiency vanillin and syringaldehyde production from lignin via g ...

O2-permeable membrane reactor for continuous oxidative depolymerization of lignin

Jeremy Luterbacher, Jean Thierry C Behaghel de Bueren

Depolymerization of lignin into aromatic monomers is one of the highest priority targets for valorization of lignin obtained from biomass pretreatment. Oxidative lignin depolymerization proceeds rapidly under alkaline conditions at elevated temperature wit ...

Current strategies for industrial plastic production from non-edible biomass

Jeremy Luterbacher, Jean Thierry C Behaghel de Bueren, Lorenz Perry Manker, Stefania Bertella

Realistically replacing petroleum-based plastics will require efficient routes to performance polymers using scalable processes from abundantly available lignocellulosic biomass. We surveyed academic and patent literature for processes in the latest stages ...

Ternary Alloys Enable Efficient Production of Methoxylated Chemicals via Selective Electrocatalytic Hydrogenation of Lignin Monomers

Jeremy Luterbacher, Jean Thierry C Behaghel de Bueren, Graham Reid Dick

We explore the selective electrocatalytic hydrogenation of lignin monomers to methoxylated chemicals, of particular interest, when powered by renewable electricity. Prior studies, while advancing the field rapidly, have so far lacked the needed selectivity ...

Dual Valorization of Lignin as a Versatile and Renewable Matrix for Enzyme Immobilization and (Flow) Bioprocess Engineering

Jeremy Luterbacher, Jean Thierry C Behaghel de Bueren, Stefania Bertella

Lignin has emerged as an attractive alternative in the search for more eco-friendly and less costly materials for enzyme immobilization. In this work, the terephthalic aldehyde-stabilization of lignin is carried out during its extraction to develop a serie ...

Continuous hydrogenolysis of acetal-stabilized lignin in flow

Jeremy Luterbacher, Songlan Sun, Jean Thierry C Behaghel de Bueren, Florent Emmanuel Héroguel, Yuan-Peng Du, Wu Lan

Using acetal-stabilized lignin we performed a truly steady state continuous high-yielding lignin depolymerization (45% monophenolics using Ni/C), which offered a window into challenges and opportunities that will be faced when processing this feedstock. Wi ...

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 ...

Aldehyde-Assisted Fractionation Enhances Lignin Valorization in Endocarp Waste Biomass

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

Highly Selective Oxidation and Depolymerization of α,γ-Diol Protected Lignin

Jeremy Luterbacher, Wu Lan, Jean Thierry C Behaghel de Bueren

Lignin oxidation offers a potential sustainable pathway to oxygenated aromatic molecules. However, current methods that use real lignin tend to have low selectivity and a yield that is limited by lignin degradation during its extraction. We developed stoic ...
