Catalysis by acids and bases : proceedings of an international symposium ... by B Imelik( )

15 editions published in 1985 in 3 languages and held by 368 WorldCat member libraries worldwide

Because of the great importance of acid catalysis in the petrochemical industry, extensive research has been carried out during the last 30 years concerning the fundamental and applied aspects of catalysis by acids. In contrast, base-catalyzed reactions have received little attention in heterogeneous catalysis. The aim of this symposium was to evaluate our knowledge of the important area of acid and base catalysis and to cover a broad range of solids, zeolite chemistry being only one aspect of heterogeneous catalysis

Valorisation de la biomasse lignocellulosique en carburant : étude de catalyseurs hétérogènes pour la réaction d'aldolisation by Emmanuelle Ligner( Book )

2 editions published in 2013 in French and held by 2 WorldCat member libraries worldwide

The utilization of lignocellulosic biomass for fuel production requires the upgrading of the various oxygen-containing compounds from which it is formed. Following biomass depolymerization, these C5 and C6-building units include organic carbonyl groups, which can be condensed into compounds of more suitable molecular weights by aldolisation. The present work aimed at understanding the structure-activity relationship of heterogeneous catalysts used for the gas-phase aldol condensation of acetone, which was used as a model carbonyl-containing compound, in the presence of dihydrogen. Most efforts were devoted to the discovery of bifunctional systems (metallic + basic characters) exhibiting stable activity for the formation of linear oligomers. Alkali-substituted zeolites were first investigated but only displayed low activity. Several key parameters were shown to determine the activity, such as the nature of the alkali counter-cation, the residual sample acidity and the zeolite structure through the diffusivity of reaction products. Basic oxides derived from spinel structures (comprising Al, Na, Zn, Co or Cu) exhibited significantly greater acetone aldolisation activities than the basic zeolites aformentioned. Higher densities of basic sites lead to an increased formation of heavy products, resulting in the inhibition of the activity. The vicinity of metallic and aldolisation sites favored the formation of linear trimers, limiting the extent of cyclization. Cu-aluminate catalysts were shown to be instable under reductive atmospheres, and it is proposed that the active catalyst was formed of metallic copper particles supported onto an aluminium-rich oxide. The Na-content of the catalyst was shown to be crucial to obtain a solid with a stable catalytic activity and selective for the formation of linear trimers. The main role of Na was to limit dehydration of reaction intermediates and to favor the formation of oligomers
Catalyseurs à base de carbones nanodispersés pour l'oxydation catalytique en phase liquide de polluants organiques par l'oxygène ou le peroxyde d'hydrogène by Elena Polyanskaya( Book )

2 editions published in 2011 in Russian and held by 2 WorldCat member libraries worldwide

Les performances de carbones synthétiques présentant différentes morphologies et chimie de surface (nano-diamant, onion, nanotubes, Sibunit-4, Sibunit-4 oxydé) et de catalyseurs supportés à base de Fe ou de Ru dans l'oxydation en voie humide par le peroxyde d'hydrogène ou l'oxygène de composés modèles ayant différentes propriétés d'adsorption et un caractère plus ou moins réfractaire à l'oxydation (phénol, éthanol, acide formique) ont été systématiquement étudiées. Les matériaux carbonés ne contenant pas de métal sont extrêmement peu actifs dans l'oxydation des composés modèles par H2O2 ou O2, quelles que soient leur morphologie et la concentration en groupements oxygénés de surface. En présence d'ions Fe(III), les carbones de type graphite accélèrent l'oxydation des substrats organiques par H2O2, alors que les nano-diamants inhibent la réaction. Une explication, basée sur la conductivité de ces matériaux, a été proposée. L'activité des échantillons Sibunit-4 oxydé dans l'oxydation par H2O2 en présence ou non de Fe(III) décroît proportionnellement avec l'augmentation de la concentration en groupements acides de surface. L'oxydation est totalement inhibée lorsque cette dernière excède la concentration en fer dans la solution, du fait de la sorption de Fe sur ces groupements fonctionnels. L'activité des catalyseurs Ru/C dans l'oxydation par l'oxygène du phénol est affectée de deux façons différentes lors de la pré-oxydation du support : la plus grande concentration en groupements fonctionnels permet une meilleure dispersion du ruthénium, alors que l'on observe simultanément une diminution de la surface spécifique des échantillons qui est défavorable à l'activité catalytique
Catalyseurs électrochimiques pour le stockage et la réduction des oxydes d'azote (NOx) by Abdelkader Hadjar( Book )

2 editions published in 2009 in French and held by 2 WorldCat member libraries worldwide

L'objectif de ce travail était de démontrer la possibilité de coupler sur un même catalyseur, la fonction de stockage et réduction des NOx (sur le baryum) avec un effet électrochimique reposant sur un système micropile. Ce système micropile est composé de nanoparticules catalytiques (Pt et Rh) déposés sur conducteur ionique par les ions O2- (YSZ) en contact avec un support conducteur électronique (SiC dopé) de façon à pouvoir générer, sous mélanges réactionnels, une force électromotrice capable de réduire électrochimiquement une partie des NOx sur le Pt et d'oxyder le CO, les hydrocarbures imbrûlés et H2 sur le Rh. L'effet micropile a été observé sur un catalyseur Pt/Ba (matériau de stockage)/YSZ/Rh enduit dans les canaux d'un filtre à particule en carbure de silicium dopé, en condition essence pauvre à 400°C et en condition Diesel à plus basse température (300°C). Une augmentation de la conversion des NOx d'environ 10% a été observé sur les catalyseurs micropile. L'effet électrochimique a été détecté par une surproduction de CO2, en milieu riche (très peu ou pas de O2) provenant de la réaction d'oxydation électrochimique du CO (produit par vaporeformage) en réagissant avec les ions O2- provenant de YSZ. De plus, des tests catalytiques ont montré que YSZ peut être utilisée comme matériau de stockage des NOx. En effet, un traitement réducteur préalable augmente fortement sa capacité de stockage des NOx
Destruction catalytique à basses températures des composés organiques volatils (COV) by Mohamad Ousmane( Book )

2 editions published in 2010 in French and held by 2 WorldCat member libraries worldwide

The aim of the work was to study two classes of catalysts for the complete oxidation of volatile organic compounds. The target application for air pollution control is the total abatement of VOC at low temperature. Mixed oxide Co3O4-CeO2, were prepared by co-precipitation method. Among them, the mixed oxide corresponding to Co/Ce atomic ratio close to 1, was the best performing. The participation of surface oxygen species and high bulk mobile oxygen were the factors determining the high activity of Co30Ce in the total oxidation of propylene and toluene. Au (2wt%) and Pd (1wt%) catalysts were prepared over typical reducible oxides, such as CeO2 and TiO2. For comparison, catalysts over Al2O3, were also prepared. Moreover, the effect on the activity of Au and Pd supported over Al2O3 doped by cerium, manganese, iron and titanium was investigated. The so prepared Au and Pd catalysts were compared in the total oxidation of propylene. It was found that the activity of gold catalysts supported over un-doped oxides varied in the order: Au2%/Al2O3 < Au2%/TiO2 < Au2%/CeO2, while a different trend was observed for palladium catalysts: Pd1%/CeO2 < Pd1%/Al2O3 < Pd1%/TiO2. For Au catalysts, the nature of the support and the extent of interaction with the support are the key factors in determining the activity, whilst for the Pd supported ones, the activity seems to be governed by the nature of Pd species, Pd0/PdO, present in the catalyst. Au2%/Ce5%/Al2O3 and Pd1%/Ce5%/Al2O3 appear the best samples. The enhanced catalytic performances were attributed to high-oxygen mobility due to a defective ceria structure induced by the insertion of Al3+ ions into the lattice and also strong metal-support interaction between nanoparticles highly dispersed

Catalyseurs supportés pour la conversion des liquéfiats de charbon by Jérôme Stihle( )

1 edition published in 2011 in French and held by 1 WorldCat member library worldwide

This work focuses on the comprehension of the catalyst parameters (textural properties and support effect) that increase the yield of the coal liquid upgrading. The current in use catalyst was design for the petroleum vacuum residue conversion. However, these two feeds present different characteristics such as the average molecular weight and the amount of heteroelement (especially O and N). To reach our goal, an in-depth characterization of the coal liquid was carried out using techniques such as GCxGC, HR-13C-NMR, FT-ICR/MS. This coal liquid analysis pointed out its strong aromatic character. Extractive solvent experiments isolated the asphaltenes and preasphaltenes and their analysis show that they have a smaller average molecular weight distribution than that of petroleum asphaltenes. Catalytic experiments were carried out at 420°C, 15MPa of H2 for 8h. It shows that the increasing mesoporous size and the bimodality (meso + macroporosity) enable to raise the mass transfer thus the diffusion coefficient which enhances the yield in lighter products. The capability of TiO2 (as a support vs Al2O3) to promote HDO reaction, enables to restrain the competition between oxygen containing compounds and pure hydrocarbons. To conclude, this work demonstrates that several parameters can enhance catalyst's performance for the coal liquid upgrading
Influence de l'atmosphère réactive sur la stabilité structurale de catalyseurs Pt1 supporté et performances associées en oxydation de CO et photogénération d'hydrogène by Caroline Dessal( )

1 edition published in 2018 in French and held by 1 WorldCat member library worldwide

This PhD work is focused on the study of ultradispersed catalysts, composed of nanometer-sized clusters or isolated atoms (single-atom catalysts, SACs) of metal, a new class of catalysts which are currently the object of worldwide interest. The Pt/?-Al2O3 and Pt/TiO2 systems were prepared, characterized and evaluated for CO oxidation and hydrogen photogeneration, respectively.Several methods of impregnation and thermal treatment were compared, in particular through platinum dispersion analysis using scanning electron microscopy (STEM). For the preparation of SACs, our choice finally turned to the incipient wetness impregnation of Pt(NH3)4(NO3)2 precursor at low loading, followed by calcination in air.For the two catalytic systems of interest, the study of the performances and the structural evolution of the catalysts during the reactions shows that isolated Pt atoms (cations) are less active than their (reduced) cluster counterparts.In the case of Pt/?-Al2O3, operando X-ray absorption spectroscopy (XAS) using synchrotron radiation, operando diffuse reflectance infrared spectroscopy (DRIFTS), and environmental microscopy (E-STEM) allowed us to monitor the SAC formation and destabilization, the latter being however limited in oxidizing conditions. Indeed, the presence of oxygen stabilizes single Pt atoms via the formation of several Pt-O-Al bonds as shown by DFT modeling, whereas the presence of a reducing compound (CO, H2) leads to the formation of Pt clusters, mobile on their support.This work highlights the possible limitations in the stabilization and implementation of SACs for catalytic reactions involving reducing conditions

Catalyseurs à base d'oxyde de manganèse pour l'oxydation en voie humide catalytique de la méthylamine by France Schmit( )

1 edition published in 2014 in French and held by 1 WorldCat member library worldwide

Heterogeneous manganese based oxide associated to titanium, zirconium or cerium dioxide catalysts (Mn-Ti-O, Mn-Zr-O and Mn-Ce-O) were prepared using different synthesis route and evaluated in the Catalytic Wet Air Oxidation (CWAO) of methylamine. Various synthesis routes were investigated to prepare the catalysts, especially the sol-gel method using block copolymers, the nano-casting approach in mesoporous silicate templates and the solvothermal synthesis. Introduction of manganese was achieved in two different ways: either ab initio, from the beginning of the synthesis or a posteriori via impregnation of the support with a manganese precursor. If the textural properties of these materials are almost unchanged after reaction, an important segregation of the manganese was sometime observed. These catalysts were evaluated in the CWAO of methylamine, a model nitrogen-containing organic molecule. All catalysts were active in the degradation of methylamine. However, those combining manganese and cerium were performing much better than the manganese-zirconium and manganese-titanium ones. Two degradation pathways were evidenced. Whatever the catalyst, the first degradation route led to the formation of NH4 +, HCOO-, NO2 - and NO3 - ions in the aqueous phase. Ammonium and formate ions were produced in equimolar amount at the beginning of the reaction and appeared as primary products. Ammonium ions were refractory toward further oxidation and accumulated in the reaction mixture, while formate ions were totally mineralized to CO2 and H2O by the end of the reaction. Nitrite and nitrate ions were detected in trace amount. The second pathway would directly and mainly lead to N2 and CO2, without any intermediate compound being detected in the liquid phase. This last pathway would account for 50% of the degradation of methylamine. At the end of the reaction, the carbon fraction in methylamine was totally mineralized to CO2 and the selectivity in molecular nitrogen reached up to 50%
Contribution des caractérisations photocatalytiques et de l'analyse de surface pour l'application de propriétés photocatalytiques en surface de substrats organiques (textiles et papiers) by Imane Benchenaa( )

1 edition published in 2014 in French and held by 1 WorldCat member library worldwide

This thesis work is part of a collaborative project with an industrial purpose aiming at the development of composite materials with photocatalytic properties (composed of TiO2 nanoparticles) obtained by sol-gel process for application on organic substrates (textiles and paper): integration of TiO2 nanoparticles into a sol-gel hybrid (organic-inorganic) matrix and dispersion of TiO2 nanoparticles in mesoporous silica microparticles. The original contribution of this work was to develop characterization by surface analysis techniques (SEM, XPS and ToF-SIMS) and correlate these results to those from the photocatalytic tests (following the degradation of a model pollutant (formic acid) in aqueous solution under UV irradiation). Complementarily to the issue of matrices porosity, surface analysis techniques (SEM, XPS and ToF -SIMS) allowed to define criteria such as availability of photocatalyst (TiO2) at the outermost surface but also the modification of the matrix around the TiO2. These criteria were used to better understand the differences in photocatalytic properties of various composite materials deposited on the surface of organic substrates
