Catalytic activity of HAlBEA and NixHAlBEA zeolites in hydrogen-assisted dehydrochlorination of 1,2-dichloroethane into vinyl chloride monomer

Rafal Baran, Anna Srebowata, I.I. Kaminska, D. Łomot, Stanislaw Dzwigaj

HAlBEA zeolite is prepared by calcination of parent TEABEA zeolite at 823 K for 3 h in air following ionic exchange with NH4NO3 solution. NixHAlBEA zeolites are prepared by impregnation of HAlBEA with an aqueous solution of Ni(NO3)2, following a drying at 333 K to obtain NixHAlBEA. The calcination…

On the graphical analysis of the impedance response of passive electrodes

Mai T.T. Tran, Oumaïma Gharbi, Mark E Orazem, Bernard Tribollet, Mireille Turmine, Vincent Vivier

The analysis of the capacitive behavior of a passive electrode is often a difficult subject because the response obtained by electrochemical impedance spectroscopy (EIS) is characterized by a non-ideal behavior that we try to model by using a constant phase element (CPE) [1, 2]. In doing so, both…

On-line inductively coupled plasma-atomic emission spectroelectrochemistry: Real-time element-resolved electrochemistry

Borhan Bin Mohamad Sultan, Oumaïma Gharbi, Kevin Ogle, Junsoo Han

Electrochemical techniques are coupled with inductively coupled plasma (ICP) atomic emission spectrometry for in-line electrolyte analyses. In this way, direct measurement of the elemental dissolution rates in real-time or element-resolved electrochemistry can be carried out, complementary to…

Low temperature dry reforming of methane on rhodium and cobalt based catalysts: active phase stabilization by confinement in the mesoporous SBA-15

N. El Hassan, M.N. Kaydouh, H. Geagea, H. Elein, Karam Jabbour, S. Casale, H El Zakhem, Pascale Massiani

Two silica supports either non porous (SiO2) or mesoporous (SBA-15) were impregnated with cobalt (12 wt%) in order to study the confinement effect on catalytic performances in dry reforming of methane. Further increase of activity was obtained by adding small amounts of rhodium (0.2 and 0.5 wt%) to…

Sensibilité de la réaction de conversion de l'éthanol en n-butanol à la structure des hydroxyapatites : mode de fonctionnement, Sensitivity of the ethanol conversion in n-butanol to the hydroxyapatite structure

Manel Ben Osman

Les hydroxyapatites (HAps) sont des matériaux basiques qui présentent des propriétés catalytiques atypiques, notamment une sélectivité importante en butanol à partir de l’éthanol. Leur versatilité en termes de composition et de morphologie, facilement contrôlée par la synthèse, s’accompagne d’une…, StructureHydroxyapatites (HAps) are basic materials which exhibit atypical catalytic properties, particularly a high selectivity in n-butanol from ethanol’s conversion. Versatility in terms of composition and morphology, easily tuned by synthesis, is accompanied by a high modularity of acid-base…

On the promotional effect of Pd on the propene-assisted decomposition of NO on chlorinated Ce0.68 Zr0.32 O2

Cyril Thomas, Olivier Gorce, Céline Fontaine, Jean-Marc Krafft, Françoise Villain, Gérald Djéga-Mariadassou

The selective catalytic reduction (SCR) of NOx assisted by propene is investigated on Pd/Ce0.68 Zr0.32 O2 catalysts (Pd/CZ), and is compared, under identical experimental conditions, with that found on a Pd/SiO2 reference catalyst. Physico-chemical characterisation of the studied catalysts along…

Electrochemical and spectroscopic evidences of corrosion inhibition of bronze by a triazole derivative

Ahmed Dermaj, Najat Hajjaji, Suzanne Joiret, Kamal Rahmouni, Abdellah Srhiri, Hisasi Takenouti, Vincent Vivier

The electrochemical behavior of the bronze (Cu–8Sn in wt%) was investigated in 3% NaCl aqueous solution, in presence and in absence of a corrosion inhibitor, the 3-phenyl-1,2,4-triazole-5-thione (PTS). The inhibiting effect of the PTS was evidenced for concentrations higher than 1 mM for the…
