Porosity Design of Shaped Zeolites for Improved Catalyst Lifetime in the Methanol-to-Hydrocarbons Reaction

Rogéria Bingre, Renna Li, Qiang Wang, Patrick Nguyen, Thomas Onfroy, Benoit Louis

Additional porosity, such as meso-and macropores, was introduced in zeolite extrudates with the intention intuit of improving the effective diffusivity of the catalysts. The samples were characterized in depth by nitrogen adsorption-desorption, mercury intrusion porosimetry, ammonia temperature…

Promoting Ag/Al2O3 Performance in Low-Temperature H2-C3H6-SCR by Thermal Pretreatment of γ-Alumina in Water

Tesnim Chaieb, Laurent Delannoy, Catherine Louis, Cyril Thomas

The present work highlights for the first time that a thermal treatment of γ-Al2O3 in water at 80 °C for 24 h prior to Ag deposition (Ag/Al2O3-OH) leads to a drastic enhancement of H2-C3H6-SCR performance at low temperature. This enhancement is attributed to the higher NOx coverage on Ag/Al2O3-OH…

LRS-1, a new delaminated phyllosilicate material with high acidity », Chem. Mater., 18(1), 34-40 (2006).

Bachar Zebib, Jean-François Lambert, Juliette Blanchard, Michèle Breysse

Well-crystallized samples of the phyllosilicate magadiite have been synthesized in their sodic form, both purely silicic and with an Al/Si ratio of 30. They have been delaminated by a procedure consisting of CTMA+ swelling in the presence of TPAOH, sonication, and calcination at 700°C to remove the…

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…

Solvent effects on the vibrational spectrum of 3-hydroxyflavone

Ari Paavo Seitsonen, Abdenacer Idrissi, Stefano Protti, Alberto Mezzetti

3-hydroxyflavone (3HF) is a widely studied molecule that acts as a simplified prototype of biological, more complex flavonoids. Its solvation mechanism is still under investigation. Here we report a joint experimental and simulation study of the vibrational properties of 3HF in gas phase and in…

Impregnation of .gamma.-Alumina with Ni(II) or Co(II) Ions at Neutral pH: Hydrotalcite-Type Coprecipitate Formation and Characterization

Jean-Baptiste d'Espinose de la Caillerie, Maggy Kermarec, Olivier Clause

The adsorption of Co(II) or Ni(II) ammine complexes from aqueous solutions onto y-alumina at neutral or near neutral pH (7 < pH < 8.2) and ambient temperature is investigated as a function of the ion concentration in the impregnating solutions, the contact and aging times, and the drying…
