Full textIn the first part of my work, I have prepared four different catalysts based on manganese oxides: a perovskite (LaMnO3), via sol-gel method; a simple oxide (Mn2O3), by rapid method and an Octahedral Molecular Sieve (OMS-2) by two different preparation methods, via solid state (OMSs) and hydrothermal method (OMSh). The physicochemical properties of these catalysts were characterized by X-ray diffraction (XRD), N2 adsorption–desorption, TGA/DTA, ICP-OES and H2-TPR. Their catalytic performances were evaluated in the oxidation of toluene. Three consecutive catalytic cycles were performed for each catalyst in order to reach steady state performances. In order to assess the stability of the catalysts under reaction conditions, the catalytic performances were studied upon long-term experiments running for 24 h at 25% of toluene conversion. Tests of toluene oxidation over a typical industrial catalyst, such as a commercial Pd/Al2O3 catalyst containing 0.78 wt% Pd, were also performed for comparison purposes. The crystalline features detected in the XRD patterns are well consistent with the formation of the desired structures. Based on their specific surface area and their low-temperature reducibility, the catalysts were ranked as follows: OMSs> Mn2O3> OMSh> LaMnO3. This trend was in good agreement with the performances observed in the catalytic removal of toluene. A kinetic model was proposed and a good agreement was obtained upon fitting with the experimental data. In the second part of my work, LaMnO3 (LM) catalysts with molar ratio of citric acid (CA) to metal nitrates (Mn and La) ranging from 0.5 to 2 (LM 0.5 to LM 2) were synthesized by citrate sol–gel method, in order to study effect of citric acid ratio on the physico-chemical properties and the catalytic performances. The physicochemical properties of these catalysts were characterized by X-ray diffraction (XRD), N2 adsorption–desorption and by inductively coupled plasma atomic emission spectroscopy (ICP-AES). Over selected samples, additional characterizations by thermogravimetric and differential thermal analysis (TGA/DTA), temperature-programmed reduction by hydrogen (H2-TPR) and X-ray photoelectron spectroscopy (XPS) were carried out. The results show that the molar ratio of citric acid to metal nitrates significantly influenced the TGA/DTA profile of gels along with the physico-chemical properties of the catalysts. The crystalline features detected by XRD are well consistent with the formation of LaMnO3 perovskite phase. Small features of Mn2O3 were detected in the diffraction patterns of all LM catalysts except for high CA/Mn+La nitrates molar ratio (1.9 and 2.0). Conversely, La2O3 peaks appeared for values ranging from 1.6 to 2, the highest intensity being detected at molar ratio equal to 2. The catalytic performances were evaluated in the oxidation of toluene, performing three consecutive catalytic cycles in order to reach steady-state performances. In order to assess the stability of the catalysts under reaction conditions, long-term experiments running for 24 h at 17 % of toluene conversion were carried out. The catalysts LM1.2, LM1.3 and LM1.5 showed the best catalytic performances in terms of toluene conversion, LM0.8 was poor performing, while LM1 and LM1.7 exhibited an intermediate behaviour

Full textVolatile organic compounds (VOCs) contribute significantly to air pollution. Several techniques are available for their elimination including the interesting catalytic oxidation. In recent years many efforts have been made to design catalysts based on transition metal oxide to replace noble metals, usually more active for this reaction, but more expensive. The main objective of this thesis is the development of a new synthesis way to produce catalysts based on metal oxide for the removal of toluene, chosen as a model VOC, using air as oxidant. The catalysts were prepared using ionotropic alginate gels as precursors. This biopolymer, a polysaccharide extracted from brown macroalgae is a block copolymer functionalized on each sugar unit by a carboxylate function. The carboxylate- cations coordination leads to the formation of gels. After drying, the matrix is eliminated by thermal treatment and this synthesis route can lead to unsupported but well dispersed metal oxides with a good control of the structure, composition and particle size. All materials obtained based on Fe, Co, Mn, Cu, were characterized by XRD, TPR, SEM, TEM, TGA, XPS, EDS, EA, and adsorption-desorption of nitrogen. Among the oxides (single and mixed oxides) evaluated as catalysts in the reaction of toluene oxidation in gas phase, the copper manganese oxide was the most promising catalyst. Its performance is attributed to the presence of the spinel mixed phase Cu1.5Mn1.5O4, obtained independently of the alginate structure. This catalyst showed no deactivation over time (75 h) or after successive uses. Its textural and structural properties were preserved. Finally, several kinetic models (power law model, Langmuir - Hinshelwood model and Mars-van Krevelen model) were fitted on experimental data. The complete analysis of the kinetic data allowed to conclude that the rate of toluene total oxidation reaction in gas phase on copper manganese mixed oxide, is best described by a Mars-van Krevelen model

Full textThe use of catalytic processes in air pollution abatement is widespread and regarded as one of the most promising methods for atmospheric pollutants removal. Heterogeneous catalysts are efficiently used to reduce toxic emissions, such as Volatile Organic Compounds (VOC), among which toluene was selected as model molecule to be used in this study. Hydroxyapatite (Ca10(PO4)6(OH)2), which was shown, through previous investigations, to be extremely useful in the field of environmental management, owing to its particular structure and attractive properties, was chosen to be the active phase support in the current work. Copper and manganese oxides, transition metal oxides which had proven to be highly active in the total oxidation of toluene in the past, were designated for the role of active phases in the presently prepared hydroxyaptite (Hap) -supported catalysts. Firstly, a close examination into the use of Hap supported binary Cu-Mn oxides with different atomic Cu/Mn composition (2; 1; 0.5) was conducted. This study showed binary oxide catalysts to be more efficient than the single transition metal oxide catalysts, and determined an optimal Cu/Mn molar ratio value equal to 2. Secondly, β-cyclodextrin (β-CD), an organic complexing agent, was employed to adjust poor copper species dispersion, a problem that limits the performances of Cu-supported catalysts. Not only was the success of using β-CD in improving Cu dispersion and reducibility revealed through physicochemical analysis, but a meticulous inspection of the interactions taking place within the synthesized system, from solution stage to that of calcined product, exposed the role of β-CD at each step of the Cu/Hap catalyst preparation, evidencing the occurrence of interactions between β-CD molecules and both Cu2+ ions derived from copper precursor and Ca2+ ions of hydroxyapatite support. Finally, an investigation of manganese speciation in Mn/Hap catalysts with different Mn loadings was carried out. Results indicated an increase in Mn average oxidation state (AOS) going hand in hand with that of Mn content. However, a lower Mn AOS turned out to be more beneficial for the catalyst’s reducibility
