Cycloaddition of Biogas-Contained CO2 into Epoxides via Ionic Polymer Catalysis: An Experimental and Process Simulation Study

Mohammad Khaja Nazeeruddin, Paul Joseph Dyson, François Maréchal, Felix Daniel Bobbink, Antoine Philippe Van Muyden, Masoud Talebi Amiri, Alexy Robert Bonnin

Biogas upgrading technologies are crucial for the production of high-purity biomethane. Efficient CO2 removal methods that are currently commercialized rely on "catch-and-release" mechanisms, and the CO2 stream is usually discharged into the atmosphere wit ...

Catalyst Evolution Enhances Production of Xylitol from Acetal-Stabilized Xylose

Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Benjamin Pierre Le Monnier, Jher Hau Yeap

We demonstrate a catalytic process for xylitol production based on the volatility and unique reactivity of diformylxylose (DFX), which can be produced at near theoretical yield from biomass and, contrary to xylose, can be easily purified by distillation. T ...

Fractionation of lignocellulosic biomass to produce uncondensed aldehyde-stabilized lignin

Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Graham Reid Dick

Lignin is one of the most promising sources of renewable aromatic hydrocarbons. Current methods for its extraction from lignocellulosic biomass—which include the kraft, sulfite, and organosolv processes—result in the rapid formation of carbon–carbon bonds, ...

Establishing Lignin Structure-Upgradeability Relationships Using Quantitative 1H-13C Heteronuclear Single Quantum Coherence Nuclear Magnetic Resonance (HSQC-NMR) Spectroscopy

Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Stefania Bertella

Lignin depolymerization could provide an attractive renewable aromatic feedstock for the chemical industry. Past studies have suggested that lignin structural features such as ether content are correlated to lignin’s upgradeability. An obstacle to the deve ...

Production and characterization of stabilized lignin

Masoud Talebi Amiri

Lignocellulosic biomass is a sustainable source of renewable carbon, and it is the most abundant form of terrestrial biomass. The three main constituents of lignocellulosic biomass are cellulose, hemicellulose, and lignin. The monomers from these biopolyme ...

Catalytic valorization of the acetate fraction of biomass to aromatics and its integration into the carboxylate platform

Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Benjamin Pierre Le Monnier, Jher Hau Yeap, Bartosz Rozmyslowicz, Ahmed Mohamed Ibrahim Elkhaiary

In many plant species, the acetate fraction is the fourth most prominent fraction by weight after cellulose, hemicellulose and lignin, and can be easily extracted as a single stable molecule, acetic acid, at high yields. Despite this, upgrading the acetate ...

Carbohydrate stabilization extends the kinetic limits of chemical polysaccharide depolymerization

Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Raquel Zambrano Varela

Polysaccharide depolymerization is an essential step for valorizing lignocellulosic biomass. In inexpensive systems such as pure water or dilute acid mixtures, carbohydrate monomer degradation rates exceed hemicellulose—and especially cellulose—depolymeriz ...

Protection Group Effects During α,γ-Diol Lignin Stabilization Promote High-Selectivity Monomer Production

Jeremy Luterbacher, Wu Lan, Masoud Talebi Amiri, Christopher Marc Hunston

Protection groups were introduced during biomass pretreatment to stabilize lignin's α,γ-diol group during its extraction and prevent its condensation. Acetaldehyde and propionaldehyde stabilized the α,γ-diol without any aromatic ring alkylation, which sign ...

Iron oxide-mediated semiconductor photocatalysis vs. heterogeneous photo-Fenton treatment of viruses in wastewater. Impact of the oxide particle size

César Pulgarin, Michaël Bensimon, Sami Rtimi, Stefanos Giannakis, Anna Carratala Ripolles, Masoud Talebi Amiri, Siting Liu

The photo-Fenton process is recognized as a promising technique towards microorganism disinfection in wastewater, but its efficiency is hampered at near-neutral pH operating values. In this work, we overcome these obstacles by using the heterogeneous photo ...

Formaldehyde stabilization facilitates lignin monomer production during biomass depolymerization

Jeremy Luterbacher, Yiming Li, Florent Emmanuel Héroguel, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Li Shuai

Practical, high-yield lignin depolymerization methods could greatly increase biorefinery productivity and profitability. However, development of these methods is limited by the presence of interunit carbon-carbon bonds within native lignin, and further by ...
