Full textFollowing the restrictions made by the United Nations and the European Community on certain halogenated flame-retardants, the current market demand tends to move towards non-halogenated compounds such as phosphorous flame-retardants. However, it is necessary to use high amounts of material for reaching interesting fire resistance properties, resulting in a drop of mechanical properties. This led us to combine a part of the phosphorous compounds with nanoscale metal oxides, known for their ability to improve the stability of poly (methyl methacrylate) (PMMA).We have first studied the effect of nanoparticles (titanium dioxide, alumina and boehmite) on the thermal diffusivity of PMMA, in order to highlight a mode of action of these additives during the thermal degradation of PMMA. A part of these metal oxides have then been substituted by two flame-retardants based on phosphorus and nitrogen: ammonium polyphosphate (APP) and melamine polyphosphate (MPP). In the obtained ternary systems (APP/MPP/metal oxide), the properties of fire resistance and thermal stability were studied and also the mechanisms involved in the degradation. Gaseous and condensed phases have been analyzed for this purpose

Full textAs regulations for emissions from gasoline engines become stricter, attention has been focused on the start-up phase (cold-start), when about 70-80% of total hydrocarbon (HC) emissions of an engine are released. This phase is a short period of 1-2 min prior to reaching the minimum catalyst operating temperature, around 200°C. In this thesis, the concept of single-file diffusion (in 1-D zeolites) was employed as a feasible approach to control automotive HC emissions during cold-start. This mechanism was investigated over a variety of zeolites with MTW structures for studying their trapping ability for lighter HC molecules, which are often desorbed before the three-way catalyst reaches its light-off temperature. In this thesis, a serie of ZSM-12 zeolites which different conterions (Na⁺, H⁺, Ag⁺) and with different Si/Al molar ratios (52, 64, 80) were synthesized. Temperature-programmed desorption (TPD) of ethylene and toluene, as models of light and heavy hydrocarbon molecules, was employed to screen these synthesized zeolites as potential HC traps. High heating rate desorption experiments were performed using the Phytronix Laser Diode Thermal Desorption system (S-960 LDTD) after desorption of toluene-ethylene mixture. Three heating rates which reflect the actual heating rate of the catalytic muffler have been used for the desorption process: 3, 5 and 9°C/s. For all solids considered in this study, the two HCs desorbed above 240°C. Ag-ZSM-12 was found the most appropriate HCs trapping adsorbent. Numerically, using a transient diffusion boundary value problem coupled with Fick’s law, it was possible to explain all qualitative features of the temperature dependent desorption profiles observed experimentally. Two steps must be considered, a cage to cage jumping followed by an escape from cage to gas phase. The two steps have different activation energies with EΓ> ED. For each component, both activation energies are strongly dependent on Si/Al ratio and radius of counterions. Moreover the effect of thermal vibration of the host lattice on diffusivities was also depicted.

Full textFrom the perspective of economic and environmental controversies over unconventional oil and gas resources, this thesis contributes to the development of integrated modelling tools intwo aspects : their ability to reflect the long-term dynamics of energy markets ; and the consideration of the links between the economy and the dynamics of the various greenhouse gases.In the first case, a set of simulations with the Imaclim-R model highlights the economic impacts of shale gas and light tight oil through (i) the links between growth paths and technicalinertia ; (ii) the conditionality of US competitiveness gains on implicit or explained strategies ; and (iii) the conditionality of US competitiveness gains on this country implicit or explicit strategies in terms of international specialization and exchange rate regime. In the course of these simulations, we study (α) the adjustment processes towards the long-term equilibrium, looking at the conditions of existence and convergence of the model temporary equilibria ; (β) the tractability limits of a stylized model of Imaclim-R reproducing the main mechanisms.In the second case, the question of the role of methane in short and long term climate strategies is addressed. The integration of the Oscar2.2 Earth System model into the Imaclim-Rmodel is used to assess the role of methane in terms of mitigation costs and to assess the risk of emissions leakage at shale gas wellheads. The simulations show that, on the one hand, theeconomic advantage of shale gas availability can be balanced against the costs induced by these emissions leakage. On the other hand, the ambitous climate strategies aiming at limitingtemperature increases well below 2° or 1.5°C require a more instant control of methane

Full textThe increase of the environmental issues drives to the integration of the environmental dimension in the product design process of companies of the mechanical industry. This process has widely evolved for the last decades, since suppliers are more deeply involved into their clients' process. As they reach a high level of responsibility, they may heavily influence the product environmental performance of a final system. Hence it is required to improve the integration of the environment in the client/supplier relationship. This integration is however limited due to three main issues : (1) an organizational issue linked the low integration of the environment in corporate hierarchical levels, (2) an operational issue which refers to the reduced environmental expertise which limits the long-term integration of the environment in the product design process, (3) a relational issue which concerns the unbalanced relationship between clients and suppliers. Our research work leads to the method GECO (Management of the Environment in the Client/Supplier relationship). It supports mechanical companies though a consistent, pro-active and tailor made approach within the management of the environment with clients and suppliers. First, the method allows companies to visualize the growing clients’ environmental issues they would potentially have to face up in short and long term. Thus it provides strategic information to focus the efforts on the relevant environmental issues. Second, the method provides a roadmap which guides companies with the choice of the relevant methods and tools to respond to the clients’ requirements. Finally, the method GECO supports the elaboration of an environmental strategy adapted to the suppliers' maturity. The method was experimented though two study cases with a large company from the railway industry and a small company of the defense sector. The relevance of the method has been confirmed, especially the diagnosis part

Full textThe purpose of this paper is to understand the values of ecosystem services obtained from different estimation methods and to provide guidance to facilitate their use for landscape management decisions. In the first chapter, we present an accounting for the ecosystems rendered by wetlands in Minganie, Québec. The accounting is divided in three categories: ecosystem services, natural capital and carbon sequestration. We proceed to analyse how these values may be used in the field and suggest that further analysis of the underlying estimation methods would help in identifying their areas of applicability. The second chapter takes a closer look at three estimations methods: replacement cost, marginal benefit methods and damage avoided costs. From this analysis it is concluded that a careful interpretation of monetary values is needed to properly guide their use in the decision making process.
