Texto completo da fonteThe recycling of rubber in the industry has become highly important due to environmental and financial reasons. A recycling approach is to devulcanize the rubber in order to reintroduce it as a raw material. This is a challenging process since the objective is to rupture the rubber network by breaking sulfur bridges without damaging the polymer chains. This work aims to study a devulcanization process known as “High Shear Mixing” (HSM). A machine was designed, built and instrumented with the purpose of studying the different phenomena occurring during the devulcanization process. During the treatment, the rubber is sheared between two cones with special geometries. During this shearing the treated rubber is self-heated, a cooling system prevents the rubber degradation due to excessive heat. The objectives were to better understand the process and the physics behind, to determine a process parameter to follow the rubber evolution and to optimize the treatment. Our analysis highlighted 2 parameters: the rubber temperature and the specific mechanical energy consumed during the process. This energy can be correlated to the degree of devulcanization of the rubber which is measured by means of physicochemical analyses. An optimal state of surface activation on the treated rubber was also described. A physical model of the rubber network evolution along the HSM treatment is proposed. To validate the recycling efficiency, the effect of adding different fractions of treated rubber in the same raw material formulation was tested. A Taguchi method was used to design formulations and HSM factors to be tested. Reformulated mixtures were vulcanized and rubber properties were analyzed

Texto completo da fonteThis work is devoted to the development of an environmentally friendly method for the valuation of waste tire. This method is based on the degradation of tires natural rubber (NR) mainly composed of cis-1,4-polyisoprene (PI), to form telechelic polyisoprene, using the Ruthenium-catalyzed olefins metathesis reaction. The ionic liquid medium was chosen for this process to allow the easy recover of the product and to limit the toxic metal contamination of the product. The IL used in this study are cyphos 101 and [DOIM][Br]. The optimization of the reaction on the PI showed that cryogenic grinding is necessary and that the degradation could be controlled by the reaction time and the concentration of PI in the IL. Under these conditions, the catalytic ionic liquid phase could be reused up to 8 times in the degradation reaction of PI. This process allowed the synthesis of amino or acetate functionalized PI. Finally, this method was applied successfully to the degradation of waste tire

Texto completo da fonteIn recent years, refineries have experienced strong imbalances in supply and demand of petroleum products due to the extraction of increasingly heavy petroleum and the high demand for light fractions such as naphtha and middle distillates. This problem has led to the research and development of new technologies for upgrading of heavy fractions with low commercial value such as atmospheric and vacuum residues. In this context, slurry-phase hydroconversion appears as an attractive technology capable of treating the heaviest feeds. However, the deep conversion of petroleum residues can’t be carried out in once-through mode. The recycling mode offers an excellent alternative to achieve the deep conversion while also providing operational flexibility to the hydroconversion units in terms of severity and catalyst consummation.The aim of this work was to study the impact of recycling mode on the slurry-phase hydroconversion performances of a vacuum residue. The first part of this work was dedicated to the reliability of a continuous micro-scale pilot unit and the generation of experimental data from this unit. For the hydroconversion experiments, three operating variables were varied: temperature, residence time and recycling rate. The experimental results obtained allowed evaluating the impact of recycling mode. In order to better understand the impact of recycling mode, the second part of this work was dedicated to the development of a model of the micro-scale pilot in recycling mode. This model was developed taking into account the chemical kinetics determined previously in a semi-batch reactor and the physical characterization (hydrodynamics and mass transfer) of the micro-scale pilot. The model was validated by comparing its predictions with experimental data

Texto completo da fonteNeodymium belongs to the lanthanide’s serie of the period system and is the key component of the permanent magnets Nd2Fe14B which are implemented in electronic devices and “green” technologies like wind turbines or electric cars and bicycles. Nowadays, only one percent of the neodymium in electronic scraps is recycled. Due to the geopolitical considerations and a strong increase of the use of permanent magnets, there is an impoverishment of the raw material resources leading to an instable market.Since some decades, few recycling processes have been developed on a lab scale without any upscaling to the industrial scale. The existing processes have several drawbacks like multiple steps to obtain the final desired product. This means that these methods have a long process time or use a large amount of chemical productsThe aim of this research was the development of a pyrochemical process, which could be an alternative to the existing recycling processes in order to extract neodymium from electronic scraps with less steps, a smaller amount of chemical products and a higher recovery rate of the rare neodymium. For this purpose a special reaction chamber has been created which resists to the severe experimental conditions induced by the use of high temperatures and corrosive molten salts. Moreover the electrochemical behaviour of neodymium in different chloride- and fluoride-based molten salts was studied in order to find the most appropriated setup.We could prove that the pyrochemical method could be the solution to recover neodymium from the old permanent magnets under its metallic form in just one single reaction step during an electrolysis

Texto completo da fonteRare earth elements (REEs) are omnipresent in high technology devices (smartphones, computers…) and are increasingly used in green technologies (wind power turbines, electric vehicles…). Due to their importance, these metals are considered critical for Europe, which has very few primary deposits. Access to these REEs can be considered through the recycling of end-of-life products, in particular through NdFeB or SmCo permanent magnets, which represent 37%, by weight, of the REEs market.In this context, this thesis studies the recycling of REEs, especially Nd, Pr and Dy from NdFeB permanent magnets, found in hard disk drives, through “eco-compatible” hydrometallurgical routes considering the use of organic acids in the leaching process as alternatives to the mineral acids, and the use of a diglycolamide (N,N,N′,N′‐Tetraoctyl diglycolamide - TODGA) as the extracting molecule as an alternative to organophosphorus compounds.Multiparametric studies were realized in order to evaluate the selective recovery of REEs from other elements present in these magnets, in particular iron.Thus, from the results obtained, two alternative methods are proposed.The first process consists in an oxidative roasting of the NdFeB magnet powder followed by two selective leaching steps that allow, after the steps of precipitation and calcination, the separation of Didymium oxide (Nd2O3. Pr2O3), dysprosium oxide (Dy2O3) and iron oxide (Fe2O3) which is non-leachable in acetic acid. The feasibility of this process has been demonstrated on synthetic mixtures of oxides having the same composition as an oxidized NdFeB magnet powder (leaching> 95%, oxide purity> 99.8%). However, the oxidative roasting conditions must be further optimized in order to reproduce the same results on the real NdFeB magnet powder.The second process starts with the complete leaching of the non-roasted NdFeB magnet powder followed by a solvent extraction step using the extracting molecule TODGA. Thereby, a two-stage solvent extraction allowed the extraction of all REEs (Nd, Pr and Dy) with excellent selectivity against other elements present in the acetic acid leachate (Fe, B, Co and Ni). The quantitative stripping of all extracted REEs was possible using an EDTA solution. In addition, a multi-stage solvent extraction, using TODGA, followed by a stripping step using water allowed the separation of Didymium and dysprosium

Texto completo da fonteThe aim of this PhD work was to propose a recycling process method of PC-ABS blend from real Waste Electrical and Electronic Equipment deposit (WEEE) deposits. This recycling process has to be able to overcome the problematic related to polymer recycling.The main constraints about recycling process are the presence of polymeric impurities after sorting step as well as mechanical reprocessing (extrusion and injection molded). Firstly, the effect of impurities on the mechanical properties (tensile and impact strength) and morphology (SEM, TEM) of PC-ABS blends have been studied. The presence of immiscible impurity deteriorates the mechanical properties of PC-ABS. The addition of an appropriate compatibilizer enhances the interface between PC-ABS and the impurity. The compatibilizer improves the impact strength and changes the morphology of this blend. Secondly, the optimization of injection molding parameters generates a change in morphology. This change leads to an increase of the impact strength.Both methods were applied to a flame retardant PC-ABS from WEEE with an impurity. The addition of a compatibilizer and the modification of injection molding parameters improve the impact strength. The presences of an impurity and a compatibilizer have a negative effect on the flame retardant properties of the PC-ABS blend
