Electrochemically CO2 conversion using homogeneous and nanostructured heterogeneous Ru (II) electrocatalysts

The reduction of carbon dioxide to desirable products is an urgent goal in favour of the environment, the energy-cycle and mankind. We report the electrochemical reduction of CO2 to carbon monoxide by means of the ho-mogeneous electrocatalyst (1), [Ru(bpy) ...

Recent progress in syngas production via catalytic CO2 hydrogenation reaction

Alimohammad Bahmanpour

Synthesis gas production through the catalytic reverse water-gas shift (RWGS) reaction is an attractive option for the conversion of CO2 to fuels. Many metal-based catalysts have been introduced for this reaction in order to provide high activity, CO selec ...

Performance Analysis of Ammonia in Solid Oxide Fuel Cells

Jan Van Herle, Suhas Nuggehalli Sampathkumar, Peter Hugh Middleton, Steve Joris

Ammonia (NH3) has 17.8 wt% hydrogen and is easily liquified at 25°C and 8 bar pressure. Ammonia is carbon-free and can be produced sustainably at large scale and low cost. Solid oxide fuel cells generate electricity with efficiencies greater than 60% and c ...

Assessment of ammonia as energy carrier in the use with reversible solid oxide cells

Jan Van Herle, Michele Zendrini

Ammonia represents one of the most promising potential solutions as energy vector and hydrogen carrier, having a higher potential to transport energy than hydrogen itself in a pressurized form. Furthermore, solid oxide fuel cells (SOFCs) can directly be fe ...

Influence of residual stresses on the buckling capacity of axially loaded steel columns

Gabriele Falconi

Over the past 60-80 years, the design methodology of steel structures comprising conventional steel profiles, such as HEA, HEB or HEM, has remained unchanged. However, during the 21st century, production methods have improved considerably. The aim of this ...

Exergy and environmental analysis of black liquor upgrading gasification in an integrated kraft pulp and ammonia production plant

Daniel Alexander Florez Orrego

The black liquor is a byproduct of the kraft pulping process that contains more than half of the exergy content in the total woody biomass fed to the digester, representing a key supply of renewable energy to the pulping process. In this work, the conventi ...

A parametric neutron Bragg edge imaging study of additively manufactured samples treated by laser shock peening

Roland Logé, Christian Leinenbach, Markus Strobl, Nikola Kalentics

Laser powder bed fusion is an additive manufacturing technique extensively used for the production of metallic components. Despite this process has reached a status at which parts are produced with mechanical properties comparable to those from conventiona ...

Techno-economic comparison of green ammonia production processes

François Maréchal, Jan Van Herle, Ligang Wang, Hanfei Zhang

To reduce the fossil-fuel consumption and the impacts of conventional ammonia production on climate change, green ammonia production processes using green hydrogen need to be investigated. For commercial production scale, potential alternatives can be base ...
