Carbon balance of a European mountain bog at contrasting stages of regeneration

Carbon dioxide and methane (CH4) fluxes were measured in a cutover bog of the Jura Mountains (France) together with biotic and abiotic variables for two entire vegetation periods in order to compare the carbon balance of the bog at three stages of regenera ...

Similarity solution of axisymmetric flow in porous media

David Andrew Barry, Marc Parlange

Applications of the axisymmetric Boussinesq equation to groundwater hydrology and reservoir engineering have long been recognised. An archetypal example is invasion by drilling fluid into a permeable bed where there is initially no such fluid present, a ci ...

Assessing Model Complexity from Anaerobic Digestion Data: When is Model AM1 Required?

Benoît Chachuat, Olivier Bernard

The anaerobic digestion ecosystem is complex, involving a broad variety of substrates and up to 140 bacterial species. This paper applies a methodology that determines the least number of macroscopic bioreactions to be taken into account in order to explai ...

Process design of Synthetic Natural Gas (SNG) production using wood gasification

François Maréchal, Claude Friedli, Alexis Joseph Duret

The process design of a 10 to 20MWth Synthetic Natural Gas (SNG) production process from wood has been performed. Combining process modeling and process integration techniques, this study proceeds via the following stages: • thermodynamic modeling: mass, e ...

Atmospheric science: Atmospheric methane and nitrous oxide of the late pleistocene from Antarctic Ice Cores

Jérôme Chappellaz

A classical method for understanding the coupling between northern and southern hemispheres during millennial-scale climate events is based on the correlation between Greenland and Antarctic ice core records of atmospheric composition. Here we present a ne ...

State-resolved gas-surface reactivity of methane in the symmetric C-H stretch vibration on Ni(100)

Thomas Rizzo, Rainer Beck, Plinio Maroni, Marco Sacchi, Thanh Tung Dang

The state-resolved reactivity of CH4 in its totally symmetric C-H stretch vibration (nu(1)) has been measured on a Ni(100) surface. Methane molecules were accelerated to kinetic energies of 49 and 63.5 kJ/mol in a molecular beam and vibrationally excited t ...

Planar and Tubular perovskite-type membrane reactors for the partial oxidation of methane to syngas

Daniel Favrat, Jan Van Herle, Stefan Diethelm, Joseph Sfeir

Dense planar and tubular oxygen separation membranes of La 0.6Ca0.4Fe0.75Co0.25O3-d were investigated as reactors for the partial oxidation (POX) of methane to syngas. Disk-shaped membranes were prepared by compaction and tubes by extrusion. Their permeati ...

N2O and CH4 variations during the last glacial epoch: Insight into global processes

Jérôme Chappellaz

The atmospheric methane concentration in ancient times can be reconstructed by analysing air entrapped in bubbles of polar ice sheets. We present results from an ice core from Central Greenland (Eurocore) covering the last 1000 years. We observe variations ...

Effects of elevated CO2 and N deposition on CH4 emissions from European mires

Edward Mitchell

[1] Methane fluxes were measured at five sites representing oligotrophic peatlands along a European transect. Five study plots were subjected to elevated CO2 concentration (560 ppm), and five plots to NH4NO3 (3 or 5 g N yr(-1)). The CH4 emissions from the ...

Materials for Methane-fueled SOFC Systems

Jan Van Herle, Stefan Diethelm, Raphaël Ihringer, Joseph Sfeir

Abstract: A short overview of recent work on electroceramic materials relevant to methane-fueled SOFC systems is given. Various fuel feed options are considered, such as pure methane, biogas, and the addition of reforming agents. The principle and implemen ...
