Cover Story: Mechanism identification and determination of the kinetic parameters are key points in the development of effective catalytic systems in the dry reforming reaction. In order to find the more appropriate rate law, which adequately describes the reaction with a selected catalyst, model discrimination can be applied to identify the existing model that best fits the experimental data. This discrimination, applied to literature data with Eley–Rideal and Langmuir–Hinshelwood Kinetic Models, was easily accomplished with the proposed ANEMONA.XLT tool. View Paper here.

Experimental Demonstration and Validation of Hydrogen Production Based on Gasification of Lignocellulosic Feedstock

  • Jürgen Loipersböck,
  • Markus Luisser,
  • Stefan Müller,
  • Hermann Hofbauer and
  • Reinhard Rauch

The worldwide production of hydrogen in 2010 was estimated to be approximately 50 Mt/a, mostly based on fossil fuels. By using lignocellulosic feedstock, an environmentally friendly hydrogen production route can be established. A flow sheet simulatio...

Magnesium Incorporation in n-CdTe to Produce Wide Bandgap p-Type CdTe:Mg Window Layers

  • Ashfaque E. Alam,
  • Ayotunde A. Ojo,
  • Jacek B. Jasinski and
  • Imyhamy M. Dharmadasa

In order to develop wide bandgap p-type window materials to use in graded bandgap devices, the effects of magnesium (Mg) in n-CdTe layers were explored. In this work, magnesium-incorporated cadmium telluride (CdTe:Mg) layers were electroplated using...

Experimental Investigation of the Gas/Liquid Phase Separation Using a Membrane-Based Micro Contactor

  • Kay Marcel Dyrda,
  • Vincent Wilke,
  • Katja Haas-Santo and
  • Roland Dittmeyer

The gas/liquid phase separation of CO2 from a water-methanol solution at the anode side of a µDirect-Methanol-Fuel-Cell (µDMFC) plays a key role in the overall performance of fuel cells. This point is of particular importance if the &micr...

Demonstration of the Use of 3D X-ray Tomography to Compare the Uniformity of Catalyst Coatings in Open-Cell Foams

  • Marie-Line Zanota,
  • Stéphanie Pallier,
  • Anaïs Dousse,
  • Joël Lachambre and
  • Valérie Meille

Coating open-cell foams by a catalytic layer is a necessary step to obtain structured catalytic foam reactors. The dip-coating method, consisting of immersing the foam in a suspension or in a sol-gel, is generally used to obtain the coating. The exce...
