Syngas production with thermo-chemically recuperated gas expansion systems: An exergy analysis and energy integration study

In spite of the large degree of energy integration in the modern syngas production units, the highly endothermic reactions of steam methane reforming and the combined steam and power generation still require a huge amount of energy that is typically suppli ...

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 ...

High-pressure NMR spectroscopic and calorimetric studies on formic acid dehydrogenation and carbon dioxide hydrogenation

Cornel Fink

Our current energy production is convenient and simple, but it is not sustainable. The negative impacts on our environment are omnipresent in the form of smog, extinction of species, and global warming. A major challenge of our generation is the transition ...

Modeling and optimization of an industrial ammonia synthesis unit: An exergy approach

An exergy modeling and optimization of an industrial ammonia unit based on steam methane reforming (SMR) process is presented. The base-case unit produces about 1000 t NH3/day [1], as well as power and steam, with no auxiliary exergy use. Some critical ope ...

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 ...

High-yield, in-situ fabrication and integration of horizontal carbon nanotube arrays at the wafer scale for robust ammonia sensors

Mihai Adrian Ionescu, Hoël Maxime Guérin, Laurent Syavoch Bernard, Elizabeth Buitrago Godinez

This paper reports the successful experimental demonstration of the localized growth of horizontal, dense carbon nanotube (CNT) arrays in situ and at the wafer scale. The selectivity and directionality of the CNT catalytic growth process along with the ade ...

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 ...
