Biomass screening for syngas production by flash photopyrolysis

Hubert Girault, Mathieu Soutrenon, Wanderson Oliveira Da Silva

A few seconds flash photopyrolysis is used as efficient screening tool for the investigation of selected biomass in producing syngas, hydrogen and biochar. This innovative approach allowed rapid pyrolysis of the biomass, which was followed by a precise gas ...

Biomass to energy: a machine learning model for optimum gasification pathways

Berend Smit, Kevin Maik Jablonka, Susana Garcia Lopez

Biomass is a highly versatile renewable resource for decarbonizing energy systems. Gasification is a promising conversion technology that can transform biomass into multiple energy carriers to produce heat, electricity, biofuels, or chemicals. At present, ...

Recent progress in syngas production via catalytic CO2 hydrogenation reaction

Oliver Kröcher, Alimohammad Bahmanpour

Synthesis gas production through the catalytic reverse water-gas shift (RWGS) reaction is an attractive option for the conversion of CO2 to fuels. Many metal-based catalysts have been introduced for this reaction in order to provide high activity, CO selec ...

Characterization of primary and aged wood burning and coal combustion organic aerosols in an environmental chamber and its implications for atmospheric aerosols

Satoshi Takahama, Nikunj Dudani, Imad El Haddad, Amir Yazdani

Particulate matter (PM) affects visibility, climate, and public health. Organic matter (OM), a uniquely complex portion of PM, can make up more than half of total atmospheric fine PM mass. We investigated the effect of aging on secondary organic aerosol (S ...

Platinum Nanoparticles on Sintered Metal Fibers Are Efficient Structured Catalysts in Partial Methane Oxidation into Synthesis Gas

Lioubov Kiwi

Efficient structured catalysts of partial methane oxidation into synthesis gas were obtained by electrochemical modification of the surface of sintered FeCrAl alloy fibers in an ionic liquid BMIM-NTf, with further introduction of platinum nanoparticles. It ...

Visualizing the importance of oxide-metal phase transitions in the production of synthesis gas over Ni catalysts

Stéphane François Jean Poitel

Synthesis gas, composed of H-2 and CO, is an important fuel which serves as feedstock for industrially relevant processes, such as methanol or ammonia synthesis. The efficiency of these reactions depends on the H-2 : CO ratio, which can be controlled by a ...

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 ...

Techno-economic evaluation of biomass-to-fuels with solid-oxide electrolyzer

François Maréchal, Jan Van Herle, Ligang Wang, Hanfei Zhang

Thermochemical biomass-to-fuel conversion requires an increased hydrogen concentration in the syngas derived from gasification, which is currently achieved by water–gas-shift reaction and CO2 removal. State-of-the-art biomass-to-fuels convert less than hal ...

Hyphenated Analytical Techniques for Studying the Speciation and Fate of Contaminants and Nanoparticles in Waste Treatment and Bioenergy Processes

Debora Foppiano

The widespread use of nanoparticles (NPs) and other potentially ecotoxic chemical compounds to enhance the quality of consumer products has raised concern about their fate in the environment. Indeed, those products have to be ultimately disposed of and alo ...

Trade-off designs and comparative exergy evaluation of solid-oxide electrolyzer based power-to-methane plants

François Maréchal, Jan Van Herle, Ligang Wang

Solid-oxide electrolyzer (SOE) based power-to-methane (PtM) system can efficiently store surplus renewable power into synthesis natural gas by electrolysis and methanation. The system performance depends on the operating point of the electrolyzer and syste ...
