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 ...

Effect of Short Reducing Pulses on the Dynamic Structure, Activity, and Stability of Pd/Al2O3 for Wet Lean Methane Oxidation

Oliver Kröcher, Davide Ferri

Natural gas is a suitable alternative to gasoline and diesel fuels to decrease the carbon footprint of the mobility and energy sectors. Unburnt CH4 is typically removed from the exhaust using palladium-based catalysts, which suffer from thermal deactivatio ...

Gas-sieving zeolitic membranes fabricated by condensation of precursor nanosheets

Michele Ceriotti, Kumar Varoon Agrawal, Pascal Alexander Schouwink, Luis Francisco Villalobos Vazquez de la Parra, Mostapha Dakhchoune, Claudia Esther Avalos, Yu Han, Rocio Semino Barbaresi

The synthesis of molecular-sieving zeolitic membranes by the assembly of building blocks, avoiding the hydrothermal treatment, is highly desired to improve reproducibility and scalability. Here we report exfoliation of the sodalite precursor RUB-15 into cr ...

Numerical investigation on water exchange of shale samples

Alessio Ferrari, Sara Incollingo

Interest in the hydraulic and mechanical characterization of shales has grown in recent years, because of their application in the context of energy geotechnics. In the frame of nuclear waste disposal shales are considered as host formations for the placem ...

CO2 Hydrogenation over Unsupported Fe-Co Nanoalloy Catalysts

Andreas Züttel, Kun Zhao, Robin Tobias Andreas Mutschler, Marco Calizzi, Nicola Patelli

The thermo-catalytic synthesis of hydrocarbons from CO2 and H2 is of great interest for the conversion of CO2 into valuable chemicals and fuels. In this work, we aim to contribute to the fundamental understanding of the effect of alloying on the reaction y ...

Design and Optimization of a Low Power and Fast Response Viscometer Used for Determination of the Natural Gas Wobbe Index

Danick Briand, Marjan Shaker, Pierre-André Farine, Gaël André Léon Farine, Conor Joseph Slater

This paper reports on the design of a microsystem-based thermal gas viscometer used for the determination of the quality of natural gas and its optimization through modification of its two main components: the hotplate and the capillary tube. Features, suc ...

Observation of methane filled hexagonal ice stable up to 150 GPa

Philippe Gillet, Richard Gaal, Livia Eleonora Bove Kado, Umbertoluca Ranieri

Gas hydrates consist of hydrogen-bonded water frameworks enclosing guest gas molecules and have been the focus of intense research for almost 40 y, both for their fundamental role in the understanding of hydrophobic interactions and for gas storage and ene ...

Steam Gasification of Carbonaceous Feedstocks via a 1.5 kWth Hybrid Solar/Autothermal Reactor

Sophia Haussener, Iacopo Guscetti

A continuous method of steam gasification through hybridization of a solar reactor with an autothermal gasification process is proposed and tested. The ability to autothermally gasify a carbonaceous feedstock within a solar reactor enables round-the-clock ...

On the physical mechanism of tip vortex cavitation hysteresis

Mohamed Farhat, Matthieu Dreyer, Ali Amini, Martino Reclari

Inception and desinence thresholds of tip vortex cavitation (TVC), generated by an elliptical NACA 16-020 hydrofoil, are measured at different flow conditions for various gas contents. It is observed that TVC often disappears at cavitation indices signific ...
