Matzen-Fredel, Anna. « Immobilisation of metathesis catalysts on mesoporous materials for the conversion of bio sourced fatty compounds ». Thesis, Lille 1, 2012. http://www.theses.fr/2012LIL10174.
Texte intégralAs fossil resources constantly decrease, the concept of bio-refinery is a most attractive approach to generate chemicals from renewable resources. In this context, unsaturated fatty acids derived from the hydrolysis of crops extracted-triglycerides are a major class of substrates. These must be converted to high added-value derivatives: catalytic transformations can play a key role in this, by converting such compounds into other functionalized derivatives. A most attractive reaction to meet this challenge is olefin metathesis. Based on product/catalyst separation and catalyst recycling issues, use of heterogeneous catalysts is of high interest.We thus prepared heterogenized commercial ruthenium catalysts. The hybrid materials were prepared in a two-step procedure: after silver salt-mediated cationization, the organometallic species were immobilized by ion exchange on mesoporous aluminosilicates of the MCM-41 family. The novel catalysts were characterized by solid-state NMR, IR, XRD, BET, elemental analysis and TGA. They were successfully applied in several metathesis reactions involving the archetypic methyl oleate, a C18 unsaturated ester, with different grades of purity. The probed reactions were self-metathesis, ethenolysis and cross-metathesis with functionalized olefins derived from acrylic and crotonic acids. Though recycling was not completely successful, the supported catalysts were able to efficiently catalyze all these transformations, providing in some instances the first heterogeneously examples of such reactions with high activity and selectivity

Texte intégralWith the aim of improving the understanding of the fire behavior of synthetic and bio-sourced composite materials, the objective of this thesis is to highlight physicochemical phenomena related to fire safety for materials that can be used in applications of aeronautics and/or automobiles. In this context, part of the experimental tests was carried out using the NexGen burner developed according to FAA requirements to carry out fire certification tests. The second part of the results was obtained using a cone calorimeter to assess the fire behavior of composite materials on a medium scale. In addition to fire certification tests, this research study focused on the development of bio-sourced composite materials. Indeed, considering the non-biodegradable nature of synthetic composite materials such as carbon-PEKK, carbon-BMI, and carbon-phenolic, the lack of work dealing with the subject and the problem of global warming, this thesis proposes a physical characterization -chemical of bio-sourced composite materials subjected to different heat flow densities. The bio-sourced composite materials manufactured as part of this thesis consist of flax fibers and banana fibers; manufactured using the VARTM method. To improve the thermo-physical properties of these materials to increase their performance from a fire safety point of view, an additional layer of flame retardant was applied to their surface. For the study of the thermal degradation of bio-sourced materials, three heat flow densities were used, notably 20, 35, and 50 kW/m². The parametric study focused on the fire performance index, the fire growth index, the mass loss, the pyrolysis flow rate, the surface temperature of the rear face and the front face of the sample, and the gaseous emissions obtained for each test configuration. Using the results, it is shown that for the configuration characterized by the most intense flame, the carbon-PEKK composite material is the most thermally stable. In addition, for the three heat flows studied, the bio-sourced composite materials present different thermo-physical behavior. Indeed, on a medium scale, materials based on flax fibers have thermal properties superior to those of materials based on banana fibers. However, on a large scale, the opposite observation was highlighted. It appears that the thermal properties of bio-sourced materials strongly depend on their size

Texte intégralThe valorization of plant waste, so abundant in Morocco, offers great potential for the development of a new sector of composite materials. Nevertheless, this potential remains under-exploited. In this context, this study was carried out to investigate the thermal and acoustical characteristics of local composite panels based on plant fibers. The aim is twofold: on the one hand, to offer an alternative solution to waste management in Morocco, and on the other hand, to improve the thermal and acoustic performance of walls.Several samples of composite materials based on plant fibers (wood chips, sawdust, crushed hemp shiv, and fibred hemp shiv) were developed to assess their thermal and acoustical characteristics.From a thermal point of view, the experimental results have shown that the majority of composites studied exhibit low values of the thermal conductivity and diffusivity. In addition, the variation in bulk density has a considerable effect on the thermal properties of the composites. In addition, the thermal inertia parameters of the exterior wall are influenced by the thermophysical properties, thickness, and position of the insulation in the wall, as well as the internal global heat exchange coefficient.From an acoustic point of view, the samples have a significant acoustic absorption capacity, particularly at high frequencies. They can absorb more than 50% of incident sound energy over a wide range of frequencies. Composite bulk density and particle size also influence acoustic absorption.In conclusion, the results obtained provide a reliable and promising assessment of the thermal and acoustic performance of plant-based insulation materials. The development of this sector will contribute to Morocco's energy efficiency development program and enrich the database of insulation materials available in the country

Texte intégralTo respond to the growing interest in ecology, the development of eco-responsible materials has become preponderant in areas such as transportation and mobility. One potential solution is to replace synthetic fibers by natural ones and virgin polymers by recycled ones. Indeed, these materials present similar specific properties and a lesser environmental footprint. However, natural fibers are very hydrophilic, which can be a problem in long-term outdoor use. As for the polymers, they undergo modifications during recycling that can affect their compatibility with fibers. This thesis' aim is to investigate how the use of a recycled matrix affects the properties of polypropylene/flax composites and their behavior under hydrothermal and cyclic ageing. First, the influence of processing parameters (compatibilizing agent's percentage, consolidation time, temperature and pressure, cooling rate and exit temperature) on the mechanical properties of virgin matrix composites was studied in order to obtain a reference material. Then, the impact of the use of recycled matrices on the properties of the composite was studied. Finally, hydrothermal and cyclic ageing (immersion, freezing and drying) were applied to all composites (with virgin and recycled matrices). A multiscale analysis combining physicochemical, structural and mechanical characterizations was carried out during ageing to better understand the influence of the matrix on the behavior of the composites over time
