Titre : Design of a lab-scale rotary cavity-type solar reactor for continuous thermal dissociation of volatile oxides under reduced pressure Type de document : texte imprimé Auteurs : Marc Chambon, Auteur ; Stéphane Abanades, Auteur ; Flamant, Gilles, Auteur Année de publication : 2011 Article en page(s) : pp. [021006/1-7] Note générale : Energie Solaire Langues : Anglais (eng) Mots-clés : Chemical reactors Solar absorber-convertors Solar heating Solar radiation Zinc compounds Index. décimale : 621.47 Résumé : A high-temperature lab-scale solar reactor prototype was designed, constructed and operated, allowing continuous ZnO thermal dissociation under controlled atmosphere at reduced pressure. It is based on a cavity-type rotating receiver absorbing solar radiation and composed of standard refractory materials. The reactant oxide powder is injected continuously inside the cavity and the produced particles (Zn) are recovered in a downstream ceramic filter. Dilution/quenching of the product gases with a neutral gas yields Zn nanoparticles by condensation. The solar thermal dissociation of ZnO was experimentally achieved, the reaction yields were quantified, and a first concept of solar reactor was qualified. The maximum yield of particles recovery in the filter was 21% and the dissociation yield was up to 87% (Zn weight content in the final powder) for a 5 NL/min neutral gas flow-rate (typical dilution ratio of 300).

Titre : Methane decarbonization in indirect heating solar reactors of 20 and 50 kW for a CO2-free production of hydrogen and carbon black Type de document : texte imprimé Auteurs : Sylvain Rodat, Auteur ; Stéphane Abanades, Auteur ; Flamant, Gilles, Auteur Année de publication : 2012 Article en page(s) : 07 p. Note générale : Solar energy Langues : Anglais (eng) Mots-clés : Chemical reactors Heating Hydrogen production Index. décimale : 621.47 Résumé : Solar methane decarbonization is an attractive pathway for a transition toward an hydrogen-based economy. In the frame of the European SOLHYCARB project, it was proposed to investigate this solar process extensively. At CNRS-PROMES, two indirect heating solar reactors (20 and 50 kW) were designed, built, and tested for methane decarbonization. They consist of graphite cavity-type receivers approaching the blackbody behavior. The CH4 dissociation reaction was carried out in tubular sections inserted in the solar absorber receiving concentrated solar irradiation. The 20 kW solar reactor (SR20) was especially suitable to study the chemical reaction and methane conversion performances depending on the experimental conditions (mainly temperature and residence time). The 50 kW solar reactor (SR50) was operated to produce significant amounts of carbon black for determining its properties and quality in the various possible commercial applications. The main encountered problem was the particle evacuation. Solutions were proposed for large-scale industrial applications. A process analysis was achieved for a 14.6 MW solar chemical plant on the basis of a process flow-sheet. A production of 436 kg/h of hydrogen and 1300 kg/h of carbon black could be obtained for 1737 kg/h of methane consumed, with an hydrogen cost competitive to conventional methane reforming. This paper summarizes the main results and conclusions of the project.
