Ethylene production via catalytic dehydration of diluted bioethanol: a step towards an integrated biorefinery

Ilenia Rossetti, Matteo Compagnoni, Elisabetta Finocchio, Gianguido Ramis, Alessandro Di Michele, Yannick Millot, Stanislaw Dzwigaj

After a preliminary thermodynamic investigation, proper operating conditions have been selected to maximize ethylene productivity by ethanol dehydration and limit side products such as coke and higher olefins or oxygenates. We focused on the possibility to operate with a diluted bioethanol solution…

Oscillatory Behavior of Pd-Au Catalysts in Toluene Total Oxidation

Tarek Barakat, Joanna Rooke, Dayan Chlala, Renaud Cousin, Jean-François Lamonier, Jean-Marc Giraudon, Sandra Casale, Pascale Massiani, Bao-Lian Su, Stéphane Siffert

In this work, the activity of bimetallic Pd-Au doped hierarchically structured titania catalysts has been investigated in the total oxidation of toluene. In earlier works, doping titania with group Vb metal oxides ensured an increased catalytic performance in the elimination of VOC molecules. A…

Esterification of fatty acids with alcohols over niobium phosphate

Iria A.L. Bassan, Danielle R. Nascimento, Rosane A.S. San Gil, M.I. Pais da Silva, Carla R. Moreira, Wilma A. Gonzalez, Arnaldo C. Faro, T. Onfroy, Elizabeth R. Lachter

The aim of this study is the evaluation of niobium catalysts (niobic acid, niobium phosphate) in the esterification reactions of fatty acids (C12-C18) with alcohols (methanol, ethanol, butanol). The catalysts were characterized by different techniques (N2 adsorption/desorption, XRD, FTIR, FTIR of…

Effect of the order of Ni and Ce addition in SBA-15 on the activity in dry reforming of methane, Effet de l'ordre d'ajout du Ni et du Ce dans SBA-15 sur l'activité en reformage à sec du methane

Marie-Nour Kaydouh, Nissrine El Hassan, Anne Davidson, Sandra Casale, Pascale Massiani

Dry reforming of methane has been carried out on SBA-15 catalysts containing 5 wt% Ni and 6 wt% Ce. The effect of the order of Ni and Ce impregnation on the catalytic activity has been studied. Both metals were added using the “two-solvent” method that favors metal dispersion inside the pores.…

Heterogeneous Partial (amm) Oxidation and Oxidative Dehydrogenation Catalysis on Mixed Metal Oxides

Jacques C. Védrine

This paper presents an overview of heterogeneous partial (amm)oxidation and oxidative dehydrogenation (ODH) of hydrocarbons. The review has been voluntarily restricted to metal oxide-type catalysts, as the partial oxidation field is very broad and the number of catalysts is quite high. The main…

Bimetallic Fe-Ni/SiO2 catalysts for furfural hydrogenation: Identification of the interplay between Fe and Ni during deposition-precipitation and thermal treatments

Dichao Shi, Qifeng Yang, Christi Peterson, Anne-Félicie Lamic-Humblot, Jean-Sébastien Girardon, Anne Griboval-Constant, Lorenzo Stievano, Moulay Tahar Sougrati, Valérie Briois, Paul A.J. Bagot, Robert Wojcieszak, Sébastien Paul, Eric Marceau

Supported Fe-Ni catalysts have been reported for their activity and selectivity in the hydrogenation of unsaturated organic molecules. However, the control of the size and composition of the bimetallic nanoparticles remains a bottleneck when oxide-supported catalysts are prepared by impregnation,…

Flavonols and 3-hydroxychromones: new applications for a class of environment-sensitive fluorescent molecules

Stefano Protti, Alberto Mezzetti

Flavonols are naturally-occuring molecules that exhibit interesting fluorescence properties. Thanks to an excited-state intramolecular proton transfer, to specific interactions with their molecular environment and to ground-state proton transfer reactions, very often a dual or even triple…

Improvement of the Catalytic Performances of SBA‐15 in the Formylation of Aniline upon the Introduction of Template‐Free Nano‐Faujasite in Its Synthesis Gel

Karima Baghdad, Mohammed Abdelkrim Hasnaoui, Franck Launay

Faujasite nanoparticles with average size of 10–40 nm were obtained without any organic structure directing agents (Green synthesis), then used as precursors for the synthesis of NaY/SBA-15 composites. Two types of composites were obtained with meso/micro porosity (C1 and C2).The inorganic salt,…
