Hydrogénation sélective du 2-butyne-1,4-diol avec des catalyseurs de palladium supportés sur des matériaux filamenteux structurés

The principal objective of this thesis is the development of a palladium catalyst supported on woven fabrics of activated carbon fibers (ACF) for the reactions of hydrogenations in liquid phase and the design of multiphase reactors using the characteristic ...

Hydrogen production for fuel cell application in an autothermal micro-channel reactor

Albert Renken, Pierre Reuse

Results concerning the coupling of the steam reforming and total oxidn. of methanol in a two-passage reactor are presented. A com. available copper-based catalyst is used for the steam reforming. For the total oxidn., a highly active cobalt oxide catalyst ...

Modeling of the high-temperature polymerization of methyl methacrylate. 1. Review of existing models for the description of the gel effect

Thierry Meyer, Philip Nising

High-temp. polymn. has recently become of interest for industry because it yields higher reaction rates, and thus less reaction time, lower viscosity, and higher conversions. However, it also leads to new challenges for process engineering in regards to ma ...

Loop reactor staged with structured fibrous catalytic layers for liquid-phase hydrogenations

Albert Renken, Lioubov Kiwi, Eric Joannet

A novel concept of a recycle loop reactor is developed with structured filamentous catalysts integrated as trays in a staged bubble column. The reactor can be operated in batch or continuous mode. Woven fabrics of activated carbon fibers (ACF) were used as ...

Study of radio-frequency plasma deposition of amorphous silicon for the improvement of solar cell production

Juliette Ballutaud

Plasma enhanced chemical vapour deposition (PECVD) of thin films such as amorphous silicon has widespread applications especially in the field of photovoltaic solar cells and thin-film transistors for flat screen production. Industrial applications require ...

Novel monolithic electrochemically promoted catalytic reactor for environmentally important reactions

Christos Comninellis, György Foti

A novel dismantlable monolithic-type electrochem. promoted catalytic reactor and "smart" sensor-catalytic reactor unit has been constructed and tested for hydrocarbon oxidn. and NO redn. by C2H4 in presence of O2. In this novel reactor, thin (.apprx.20-4 ...

Plutonium management in the medium term

Rakesh Chawla

For many years various countries with access to commercial reprocessing services have been routinely recycling plutonium as UO2/PuO 2 mixed oxide (MOX) fuel in light water reactors (LWRs). This LWR MOX recycle strategy is still widely regarded as an interi ...

Improving plasma uniformity using lens-shaped electrodes in a large area very high frequency reactor

Christoph Hollenstein, Alan Howling, Laurent Fabien Hubert Sansonnens, Hannes Schmidt

Experiments using a lens-shaped circular electrode are described to measure the correction of plasma nonuniformity due to the standing wave effect in a large area very high frequency plasma reactor. This work is the experimental verification of the theoret ...

Micro-structured string-reactor for autothermal production of hydrogen

Albert Renken, Lioubov Kiwi, Chrystèle Horny

Novel micro-structured string-reactor designed as catalytically active wires placed in parallel into a tube was developed. The small diam. of the channels (.apprx.100 mm) leads to a short radial diffusion time, a narrow residence time distribution, and a l ...
