Dehydrogenation of Formic Acid over a Homogeneous Ru-TPPTS Catalyst: Unwanted CO Production and Its Successful Removal by PROX

Gabor Laurenczy, Nordahl Autissier, Veronica Henricks

Formic acid (FA) is considered as a potential durable energy carrier. It contains ~4.4 wt % of hydrogen (or 53 g/L) which can be catalytically released and converted to electricity using a proton exchange membrane (PEM) fuel cell. Although various catalyst ...

Future experimental programmes in the CROCUS reactor

Andreas Pautz, Vincent Pierre Lamirand, Mathieu Hursin, Oskari Ville Pakari, Pavel Frajtag

CROCUS is a teaching and research zero-power reactor operated by the Laboratory for Reactor Physics and Systems Behaviour (LRS) at the Swiss Federal Institute of Technology (EPFL). Three new experimental programmes are scheduled for the forthcoming years. ...

On the Use of Second-Order Modifiers for Real-Time Optimization

Dominique Bonvin, Timm Faulwasser

We consider the real-time optimization of static plants and propose a generalized version of the modifier-adaptation strategy that relies on second-order adaptation of the cost and constraint functions. We show that second-order adaptation allows checking ...

Wastewater treatment processes modelling for anaerobic digestion effluents

Miriel Steudler

The general topic of this research project is the modelling of wastewater treatment processes for anaerobic digestion effluents, which are characterized by high nitrogen concentrations. In order to avoid eutrophication of lakes and rivers caused by nutrien ...

Insight into the decomposition pathway of the complex hydride Al3Li4(BH4)(13)

Elsa Callini

The decomposition pathway of the complex hydride Al3Li 4(BH4)13 is in the focus of this study. Initially the compound attracted great interest due to its high H2 capacity (17.2 wt.%) and desorption at moderate temperatures (<100 °C). This work sheds lig ...

Biphasic Model Describing Soybean Oil Epoxidation with H2O2 in Continuous Reactors

Albert Renken

Epoxidized soybean oil (ESBO) is produced in industry by reacting soybean oil, at 60-70 degrees C, with hydrogen peroxide in the presence of formic or acetic acid. A small amount of sulphuric or phosphoric acid is necessary to catalyze the oxidation of the ...

The generation IV gas-cooled fast reactor

Manuel Alexandre Pouchon, Konstantin Mikityuk

The gas cooled fast reactor (GFR) is a helium-cooled fast spectrum reactor operating within a closed fuel cycle. It combines the advantages of fast reactors, in terms of a more sustainable use of uranium resources and waste minimisation, with the wider app ...

Structured catalytic wall microreactor for efficient performance of exothermic reactions

Lioubov Kiwi, Bryan Bromley, Marina Ruta, Turan Eslanloo Pereira

A novel microreactor with structured catalytic wall (SCWMR) has been developed for highly exothermic, gas/solid reactions and tested for the selective acetylene hydrogenation. The reactor design is similar to the so-called "slit microreactor". The structur ...

Cross-section modelling effects on pressurised water reactor main steam line break analyses

Rakesh Chawla, Hakim Ferroukhi, Omar Zerkak

Because of the strong asymmetric overcooling effects occurring during a PWR main steam line break (MSLB) event, an accurate analysis of this transient requires the use of 3-D kinetics methods. An assessment has been made of the relative performance of the ...
