Revisiting the concept of extents for chemical reaction systems using an enthalpy balance

Dominique Bonvin, Diogo Filipe Mateus Rodrigues

For the investigation of complex reaction systems, it has been proposed to decouple the various rate processes using a linear time-invariant transformation that is constructed from knowledge of stoichiometry, reaction enthalpies, inlet compositions and tem ...

A novel reactor concept for thermal integration of naphtha reforming with propane ammoxidation

Alimohammad Bahmanpour, Samira Ebrahimian

In this study, propane ammoxidation as an exothermic process is thermally coupled with the endothermic naphtha reforming process which resulted in the elimination of the naphtha reforming furnaces. Both processes are available in petrochemical plants. Naph ...

Fast real time and quantitative gas analysis method for the investigation of the CO2 reduction reaction mechanism

Andreas Züttel, Emanuele Moioli, Wen Luo, Robin Tobias Andreas Mutschler

We present a new fast real time and quantitative gas analysis method by means of mass spectrometry (MS), which has approximately an order of magnitude faster sampling rate in comparison with a traditional gas chromatography. The method is presented and dis ...

Alkali Activation of AOD Stainless Steel Slag Under Steam Curing Conditions

Muhammad Salman, Ruben Anton Snellings

Crystalline argon oxygen decarburization slag, in powdery form, was investigated for its hydration potential by alkali activation and curing at 80 degrees C. Na-silicate and K-silicate of the same modulus were used as activators. Isothermal calorimetry at ...

Fine structuration of low-temperature co-fired ceramic (LTCC) microreactors

Albert Renken, Paul Muralt, Lioubov Kiwi, Thomas Maeder, Bo Jiang, Julien Haber

The development of microreactors that operate under harsh conditions is always of great interest for many applications. Here we present a microfabrication process based on low-temperature co-fired ceramic (LTCC) technology for producing microreactors which ...

Nanocalorimetric platform for accurate thermochemical studies in microliter volumes

Martinus Gijs, Thomas Lehnert, Raphaël Etienne Jean Trouillon, Rima Padovani

A straightforward and general way for monitoring chemical reactions is via their thermal signature. Such approach requires however an experimental setup with a high thermal stability that simultaneously allows time-resolved heat detection with high sensiti ...

Continuous Production of Tailored Silver Nanoparticles by Polyol Synthesis and Reaction Yield Measured by X-ray Absorption Spectroscopy: Toward a Growth Mechanism

Christian Ludwig, Heinrich Hofmann, Paul Bowen, Frank Nüesch, Andrea Testino, Jose Enrico Quijano Quinsaat

Two complementary topics are discussed: (i) the continuous production of silver nanoparticles (AgNPs) and (ii) the measurement of reaction yield by X-ray absorption near-edge spectroscopy (XANES). The continuous polyol synthesis of AgNPs in grams amount an ...

Infrared imaging of temperature profiles in microreactors for fast and exothermic reactions

Albert Renken, John Richard Thome, Lioubov Kiwi, Navid Borhani, Madhvanand Namadeo Kashid, Julien Haber

Though microreactors provide high heat transfer rates, temperature profiles are formed in case of fast and highly exothermic reactions. A method based on non-intrusive infrared thermometry has been developed to track these profiles quantitatively with a re ...

Micro-batch reactor for catching intermediates and monitoring kinetics of rapid and exothermic homogeneous reactions

Albert Renken, Lioubov Kiwi, Madhvanand Namadeo Kashid, Petra Prechtl, Olivier Détraz, Mireia Santacana Moya

The mechanism and kinetics of rapid and exothermic reactions is difficult to study using conventional offline techniques. This paper deals with experimental investigations of highly exothermic and fast model reaction (cyclisation of pseudoionone) using slu ...
