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 ...
Royal Soc Chemistry2024Assessing the effect of O2 dithering on CH4 oxidation on Pd/Al2O3
Under periodic lean/rich operation generated by repeated O2 pulses (O2-dithering), the abatement of CH4 and NO is enhanced compared to static operation. However, it is not well understood how the dithering parameters (pulse amplitude and frequency) affect ...
ELSEVIER SCIENCE SA2023Intentional oxygen oscillations on Pd/Al2O3 for enhanced methane removal from the exhaust of natural gas engines
Natural gas (NG) is a suitable alternative to gasoline and diesel fuels to decrease the carbon footprint of the mobility and energy sectors. Although NG is considered a fossil fuel, methane (CH4), its main component, can be produced industrially from power ...
EPFL2022Amine Functionalization in Porous Adsorbents for Carbon Capture and Conversion
Metal-organic Frameworks (MOFs) are a class of crystalline porous materials with exceptionally high surface area, chemical tunability and stability. Due to alarming CO2 emission and global concern, research is focused on developing porous materials like MO ...
EPFL2022Monomeric Fe Species in Square Planar Geometry Active for Low Temperature NH3-SCR of NO
Monomeric Fe species in zeolites are considered to be the active sites for the low temperature activity toward ammonia-assisted selective catalytic reduction of nitrogen oxides (NH3-SCR) in exhaust gases. Herein, we report on a preparation method to synthe ...
AMER CHEMICAL SOC2022A data-science approach to predict the heat capacity of nanoporous materials
Berend Smit, Susana Garcia Lopez, Elias Moubarak, Balázs Álmos Novotny, Seyedmohamad Moosavi, Daniele Ongari, Mehrdad Asgari, Andres Adolfo Ortega Guerrero, Özge Kadioglu
The heat capacity of a material is a fundamental property of great practical importance. For example, in a carbon capture process, the heat required to regenerate a solid sorbent is directly related to the heat capacity of the material. However, for most m ...
NATURE PORTFOLIO2022Optimization of the Distance between Cylindrical Light Distributors Used for Interstitial Light Delivery in Biological Tissues
Georges Wagnières, Aurelien Stephen Arnaud Gregor
Cylindrical light diffusers (CLDs) are often employed for the treatment of large tumors by interstitial photodynamic therapy (iPDT) and photoimmunotherapy (PIT), which involves careful treatment planning to maximize therapeutic dose coverage while minimizi ...
MDPI2022In situ spectroscopic studies of the effect of water on the redox cycle of Cu ions in Cu-SSZ-13 during selective catalytic reduction of NOx
Davide Ferri, Rob Jeremiah G. Nuguid
The effect of water on the NH3-assisted selective catalytic reduction of NOx (NH3-SCR) has been largely neglected, despite the inevitable presence of water vapor in real emissions produced by fuel combustion. In this work, we investigated the role of water ...
ROYAL SOC CHEMISTRY2022Flexible application of biogas upgrading membranes for hydrogen recycle in power-to-methane processes
Oliver Kröcher, Andreas Gantenbein
Direct methanation of biogas converts the CO2 in raw-biogas to methane, enabling higher methane yield and an elelctricity storage option via Power-to-Gas. As the thermodynamic equilibrium limits the methane yield, unreacted hydrogen has to be removed and r ...
PERGAMON-ELSEVIER SCIENCE LTD2021Using stratospheric aerosol injection to alleviate global warming: when?
Marie-Valentine Renée Agnès Florin
Stratospheric aerosol injection (SAI), a type of solar radiation modification (SRM), has the potential to reduce global warming caused by excessive greenhouse gases in the atmosphere. However, there is currently widespread opposition to it, because deployi ...
