Conception raisonnée de catalyseurs bifonctionnels : élaboration de catalyseurs Pt0/zéolithe-Alumine, Rational design of bifunctional catalysts : development of Pt0/zeolithe-alumina catalysts

Olfa Ben Moussa

Les catalyseurs bifonctionnels pour l’hydrocraquage nécessitent à la fois des sites acides de Brønsted et des sites métalliques. L’intimité entre sites acides et sites métalliques peut donc influer sur l’activité et la sélectivité de la réaction. Nous nous sommes proposés d’explorer l’effet de la…, Bifunctional hydrocracking catalysts require both Brønsted acid sites and metal sites. Hence, the intimacy between acid sites and metal sites can influence the activity and selectivity of the reaction. We intended to explore the effect of metal sites-acid sites distance on the conversion of n-…

Low temperature dry methane reforming over Ce, Zr and CeZr promoted Ni–Mg–Al hydrotalcite-derived catalysts

Radosław Dębek, Maria Elena Galvez, Franck Launay, Monika Motak, Teresa Grzybek, Patrick da Costa

Hydrotalcite derived catalysts promoted with Ce, Zr and CeZr showed considerable activity in dry methane reforming (DMR) at low temperatures (550°C). Direct methane decomposition resulting in the extensive formation of fishbone-type carbon nanofibers was substantially inhibited in the presence of…

Investigation of the collapse of bubbles after the impact of a piston on a liquid free surface

Maya Mounir Daou, Elena Igualada, Hugo Dutilleul, Jean-Marie Citerne, Javier Rodríguez-Rodríguez, Stéphane Zaleski, Daniel Fuster

A novel technique based on the impact of a piston on a liquid confined in a vessel is described. Pressure measurements reveal that strong pressure variations (up to 100 atmospheres) with a rich content of frequencies are efficiently transmitted to the liquid. High-speed camera visualizations show…

Synthesis of small Ni-core–Au-shell catalytic nanoparticles on TiO2 by galvanic replacement reaction

Julien Reboul, Z. y Li, Jun Yuan, Kazuki Nakatsuka, Masakazu Saito, Kohsuke Mori, Hiromi Yamashita, Yu Xia, Catherine Louis

We report the first preparation of small gold–nickel (AuNi) bimetallic nanoparticles (<5 nm) supported on titania by the method of galvanic replacement reaction (GRR), evidenced by the replacement of Ni atoms by Au atoms according to the stoichiometry of the reaction. We showed that this…

PEDOT nanostructures synthesized in hexagonal mesophases

Srabanti Ghosh, Hynd Remita, Laurence Ramos, Alexandre Dazzi, Ariane Deniset-Besseau, Patricia Beaunier, Fabrice Goubard, Pierre-Henri Aubert, François Brisset, Samy Remita

We describe a single step preparation of nanostructures of poly(3,4-ethylenedioxythiophene), PEDOT, in the hydrophobic domains of cationic surfactant-based hexagonal mesophases via chemical oxidative polymerization of EDOT monomers using FeCl3 as an oxidizing agent. After polymerization, the…

Corrosion propagation monitoring using electrochemical noise measurements on carbon steel in hydrogenocarbonated solution containing chloride ions

Chloé Comas, François Huet, Kieu Ngo, Marion Fregonese, Hassane Idrissi, Bernard Normand

The propagation of localized corrosion on API 5 L X65 carbon steel in hydrogenocarbonated solution containing chloride ions was monitored during long immersion times by electrochemical noise (EN) measurements in ZRA mode. Monitoring corrosion propagation from the EN amplitude is possible but…

The remarkable effect of the preparation procedure on the catalytic activity of CoBEA zeolites in the Fischer-Tropsch Synthesis

Karolina A. Chalupka, Sandra Casale, Ewa Zurawicz, Jacek Rynkowski, Stanislaw Dzwigaj

This work deals with the investigation of the influence of the preparation procedure and Co content on the activity of CoBEA zeolite in Fischer – Tropsch synthesis. For this purpose the Co-containing zeolites were prepared by a conventional wet impregnation (CoxAlBEA series) and a two-step…
