Pełny tekst źródłaIn many metallic deposits, especially in sedimentary context and particularly in black shales, spatial or genetic relationships are described between organic matter and metals. Several black shales/schists affected by increasing thermo barometric conditions were selected to study the behavior and fate of uranium from sedimentation to high grade metamorphism. In shallow buried cambro ordovician Alum Shales (Sweden), uranium is dispersed and is not detectable as a particular mineralogical expression. Thermal maturation of the Alum Shales and hydrocarbon generation did not cause any identifiable remobilization of primary concentration, since migrated hydrocarbons did not carry uranium. In contrast, greenschist facies metamorphism associated with the Caledonian orogeny resulted in a re expression of uranium mineralization as uraninite or urano titanate crystals, which may evolve into U Ti Zr Y phospho silicates. In the case of Talvivaara, amphibolite facies metamorphism caused remobilization of synsedimentary uranium and synmetamorphic crystallization, during Svecofennian orogeny at 1880 1870 Ma, of uraninite crystals that are frequently included in carbonaceous nodules. This study shows that uranium, which is preconcentrated during sedimentation, remains immobile in the early stages of burial but is remobilized with increasing PT conditions and crystallizes as uranium oxides and/or uranium (phospho-)silicates

Pełny tekst źródłaResearch work presented in this phD thesis was financed by a CIFRE grant given to Groupe Dacquin. Ground from the city of Rennes is, for the majority of it, composed of schists from the Brioverian era. These schists which can be encountered in the entire Armorican massif, present a weathering and a fracturing degree highly variable. This variability is hardly considered for the construction of retaining structure whether during the design step or the execution step. First, modellings using the finite elements method (PLAXIS 2D ©) have been carried out in order to evaluate the influence of ground anisotropy on the retaining wall behaviour (horizontal displacements and bending moments). The model used combined elastic anisotropy with an oriented plasticity criterion (type Mohr-Coulomb). Results obtained with this model, for different orientations of the plasticity criterion, were compared with the ones from the elastic isotropic model (with a Mohr-Coulomb plastic criterion). The same study was carried out with another finite elements software (CESAR-LCPC) in order to compare the results between the two sofwares. In both cases, an important influence of the orientation of the plasticity criterion was noted and lead to higher efforts in the wall, for certain orientations, compared to the isotropic model. These results confirmed the need of a better characterization of the anisotropy in materials such as Brioverian schists. In a second time, the characterization of the material was carried out on samplings spread over the city of Rennes and its area (during excavation work or on natural banks). Characterization was conducted from the microscopic to the macroscopic scale. Microscopic characterization based on observations with a scanning electron microscope, XRD analyses and thin section observations showed variations in the petrography of the samples (schistosity, granulometry, clay content) that lead to the differentiation of two types: sandstone and siltstone. The characterization at the macroscopic scale was divided into three parts: characterization of the rock matrix and its anisotropy (uniaxial compression tests, ultrasonic wave velocities and Schmidt hammer test), characterization of opened discontinuities (direct shear test) and the characterization of wear resistance (grindability and Micro-Deval tests). Siltstone samples were extremely sensitive to the water content (important decrease of the mechanical characteristics measured) whereas sandstones were less sensitive. The tests carried out lead to the definition of ranges for the mechanical properties of the Brioverian schists. Classification of Brioverian schists established by geotechnical engineers for the second subway line of Rennes was completed in order to better define the transitional states of strength of the material

Pełny tekst źródłaThe structure of a combustion front propagating in a fixed bed of crushed oil shale: co-current configuration. The propagation of a combustion front in reactive porous medium involves thermal, chemical and fluid flow mechanisms, with strong couplings. In order to describe the thermal and chemical structure of the combustion front, a new experimental device, finely instrumented, allowing to carry out 1D experiments in co-current combustion was designed and developed. To validate the combustion cell, a porous medium model - a mix of charcoal/sand was used. This fixed bed down flow reactor is equipped with an original system that allows micro sampling gas within the combustion front. For the experiments with the oil shale from Timahdit in Morocco, it was crushed and sieved into particle size at 500-1000 µm and mixed with sand. The combustion was carried out at air velocity of 0. 024 m s-1 at STP. The front propagates at 6. 13x10-5 m s-1 and its temperature peak is 1100 °C. A mass balance was made based on a detailed chemical and physical characterization of the medium, its solid residue after combustion and flue gas. The organic matter is converted into 1/4 of fixed carbon – which the oxidation reactions provide the energy to propagate the front -1/4 into pyrolysis gas and 1/2 into oil. A two temperature numerical model developed by IMFT was validated. Combining, experimental and numerical approach made it possible in fine to evaluate the thickness of the different reaction zones: oil shale devolatilization, fixed carbon oxidation and CaCO3 decarbonation. A parametric study varying the air velocity and particle size is finally proposed

Pełny tekst źródłaThe transformation of an oil shale sample from the Autun Basin in the Massif Central, France, was studied using microwave irradiation and conventional heating. Both methods led to similar liquid products yield, whereas the overall energy requirements were much lower using microwaves. The influence of water vapour in oil shale decomposition was studied under microwave energy. Oil shale samples were mixed with BEA zeolite to study the effect of its acidic character on oil shale transformation and resulting products characteristics. Liquid products yield decreased under these conditions, along with an increase in coke production. Gaseous and liquid products analysis showed a tendency for the production of lighter components when in the presence of zeolite. Y and BEA zeolites were treated with an alkaline solution at different reaction conditions. An increase in the total pore volume was observed, along with increased catalytic activity for the n-decane hydrocracking reaction at 30 bar. A microwave cavity was constructed for in situ IR spectroscopy studies performed while the sample is irradiated with microwaves. The results confirm the ability of microwaves to induce rapid variations in the sample and in the reaction temperature, and also, the suitability of such reactor for performing operando studies of catalytic systems

Pełny tekst źródłaThe high cost of the activated carbon has motivated the search of low cost adsorbents such as industrial by-products. In this sense, the use of industrial by-products of oil shale: Oil Shale (XC), Pirolized Oil Shale (XR) and Pirolized Oil Shale with Tires (XRP), from PETROSIX/PETROBRAS, and the spent catalyst (CAT), from FCC (Fluid Catalytic Cracking) unit were characterized and used in this work in the adsorption of organics compounds of industrial liquid effluent. The main contribution of this thesis is to propose a mathematical model to the adsorption process of organic compounds in oil shale, spent catalyst of FCC and powdered activated carbon. This model is based on HSDM (Homogeneous Surface Diffusion Model) model and on the hydraulic behavior of the adsorbent system. Other contribution is the structural and chemical characterization of several samples of oil shale (oil shale, Pirolized oil shale and Pirolized oil shale with Tires) and of the spent catalyst of FCC. A computational model to simulate the adsorption process of these materials is also developed and can be considered an additional contribution of this work. Experimental and simulated results allow characterization of the oil shale adsorbent as basically macroporous and with superficial area about 0.51 to 3.36 m2.g-1. In addition, they present the same crystal structures and clay micrografies characteristics. The adsorbent CAT is composed basically by Faujasite, silica and alumina. They present spherical beads, irregular forms and micropores, with superficial area characteristics of zeolitic materials (148 and 155 m2.g-1). The adsorption tests realized in the synthetic and industrial effluents (Phenolic and Petrochemical) showed the potential of application of the industrial by-products of oil shale and CAT in the removal of organics compounds (dyes, Phenol and COT) of these effluents. In respect of environmental standards to effluents disposal (CONAMA resolution 357), simulations results, obtained with the proposed model, has demonstrated that the use of only oil shale or CAT is not viable, because the high quantity of adsorbents required. However, such adsorbents can be used in the reduction of organic loads in both effluents, when combined with other processes. Each adsorbent showed be used where it is produced because of transportation cost. The CAT is indicated for the treatment of Petrochemical effluent while the others adsorbents may be applied in the phenolic effluent treatment.

Pełny tekst źródłaO estudo fitoquímico e biológico das espécies S. lentiscifolius, S. terebinthifolius, S. molle e S. polygamus conhecidas como ―aroeiras‖ (Anacardiaceae), distribuídas no Rio Grande do Sul, foi realizado visando o estabelecimento da composição química de óleos voláteis obtidos por hidrodestilação das partes aéreas (folhas, flores e frutos) coletadas em diferentes estações do ano. Além disso, folhas e frutos foram analisados e comparados para determinar as variações sazonais na constituição dos óleos. A composição química dos óleos foi determinada através de Cromatografia Gasosa acoplada à Espectrometria de Massas (CGEM). Os rendimentos dos óleos essenciais das partes aéreas das espécies estudadas variaram de 0,14-2,13%, dependendo do estágio de desenvolvimento e da parte coletada. Aproximadamente cento e trinta e cinco compostos foram identificados a partir dos óleos essenciais, representando aproximadamente 90% dos óleos das folhas, flores e frutos, coletados entre a primavera e o verão no período 2005 a 2011. Os óleos volatéis das espécies analisadas apresentaram um padrão qualitativo constante dos compostos: α-pineno, β-pineno, δ-2-careno, limoneno como monoterpênicos majoritários; germacreno-D, biciclogermacreno, δ-cadineno, espatulenol, óxido de cariofileno -cadinol com os esquiterpenos majoritários no óleo das folhas; α-pineno, mirceno epi-cubenol, cubenol, espatulenol como sesquiterpenos majoritários no óleo das flores; α-pineno, β-pineno mirceno como monoterpenos e epicubenol, cubenol, espatulenol, óxido de cariofileno e -cadinol como sesquiterpenos majoritários no óleo dos frutos. As variações quantitativas entre os diferentes constituintes 7 nos óleos das diferentes espécies foram marcantes. Adicionalmente, considerando-se o potencial terapêutico e os compostos descritos para o gênero, foi realizado o estudo fitoquímico e avaliadas as atividades antimicrobianas e antioxidantes dos óleos, dos extratos brutos, dos aquosos, dos compostos isolados e dos derivados. Os extratos aquosos obtidos do processo de hidrodestilação, parte foi seco por liofilização parte foi submetido à partição líquido-líquido com os solventes hexano, acetato de etila e n-butanol. Além desses, foi preparado o extrato bruto das folhas de S. lentiscifolius. O fracionamento cromatográfico do extrato bruto de acetato de etila de S. lentiscifolius levou ao isolamento do álcool graxo (119), ácido morônico (120). Também foram obtidos dois derivados do ácido morônico (120), por reação de redução empregando NaBH4, os quais foram caracterizados como ácido morólico (121) eácido 3-epi- morólico (122). A análise do extrato aquoso de acetato de etila de S. lentiscifolius levou ao isolamento do composto FLA-1 (115) e do ácido gálico (116), do qual foi obtido o derivado galato de metila (118). Do extrato aquoso n-butanólico de S. molle foi isolado o flavonóide quercetina (90) e rutina (117). As substâncias foram identificadas por dados físicos e técnicas espectroscópicas (RMN de 1H, 13C, COSY, HMQC e HMBC) espectrometria de massas e raios-X. A análise dos extratos aquosos por Cromatografia Líquida de Alta Eficiência (CLAE) levou à caracterização do ácido gálico (116), quercetina (90) e rutina (117) por comparação com padrões existentes no laboratório. Todos os extratos apresentaramo ácido gálico (116), exceto nos extratos de S. molle. A atividade antimicrobiana dos óleos das espécies S. lentiscifolius, S.terebinthifolius, S.molle e S. polygamus foram avaliadas pelo método de microdiluição frente uma coleção de microorganismos patogênicos, compostos por bactérias e fungos. Os resultados demonstraram que os óleos obtidos das diferentes plantas foram ativos frente à maioria dos microorganismos testados. Os melhores resultados foram encontrados para os óleos dos frutos de S. terebinthifolius. Os extratos brutos e frações de S. lentiscifolius, S. terebinthifolius e S. molle foram testados também quanto à sua atividade antibacteriana e antifúngica. Os melhores resultados foram encontrados para o extrato de S. lentiscifolius com uma Concentração Inibitória Mínima (CIM) 31,2- 12,5μg/mL. Além disso, os extratos e os compostos isolados foram avaliados quanto à atividade antioxidante, utilizando-se 2,2-difenil-picrilhidrazil (DPPH). Todos os extratos e compostos testados apresentaram resultados de inibição ao radical livre DPPH.

Sobre la continuidad en la crítica contemporánea respecto del tránsito de Husserl hacia el idealismo trascendental". Pontificia Universidad Católica del Perú, 2016. http://repositorio.pucp.edu.pe/index/handle/123456789/119241.
Pełny tekst źródłaSe reconoce generalmente que hay dos cismas en la historia temprana delmovimiento fenomenológico. El primero, el “gran cisma fenomenológico”, comenzó entre los años 1905 y 1913 y, como muchos de sus jóvenes contemporáneos, por ejemplo Pfänder, Scheler, Reinach, Stein e Ingarden, rechazó la transformación husserliana de la fenomenología de las Investigaciones lógicas (1900/1901) –esto es, de la fenomenología como psicología descriptiva– a la fenomenología de Ideas 1 (1913) –esto es, lafenomenología como idealismo trascendental. El segundo, el “cisma fenomenológicoexistencial”, tuvo lugar entre 1927 y 1933, desde que en Ser y tiempo (1927) la filosofía heideggeriana se apartó de la fenomenología transcendental husserliana de la conciencia y se encaminó hacia una analítica ontológica de la existencia humana como la vía hacia una interpretación de la pregunta por el sentido del Ser. Este ensayo no gira en torno ni al primero ni al segundo cisma per se, sino que trata de la relación entre los dos. Se sugiere que el primer cisma anticipa al segundo y que el segundo recapitula al primero,de manera que, aunque el primero pudiera haber ocurrido sin el segundo, el segundo no habría ocurrido, como fue el caso, sin el primero. Se indica que el segundo cisma yace temporalmente de manera más próxima al primero de lo que hasta la actualidad se ha apreciado. Con todo, el ensayo busca responder a la siguiente pregunta: ¿cómo es que el “gran cisma fenomenológico” y el “cisma fenomenológico-existencial” se iluminan el uno al otro filosóficamente?

Pełny tekst źródłaThis dissertation consists of a comprehensive appraisal of the development of humanism in the context of the return of the pontifical court in Italy at the time of a major crisis, the Great Western Schism. Our work primarily aims at linking two stories, generally conceived as distinct, and enlightening interactions between them. These are, firstly, the emergence of a generation of intellectuals that are considered to be representatives of a humanism that reached its full maturity after a century and a half of gestation and, secondly, the re-establishment of the pontifical power in Rome, a political enterprise whose first phase was characterized by a long and very complex struggle for unity and stability. This thesis is as follows : it examines firstly the construction of a scholarly network, secondly its relationship to historical and institutionnal contexts, namely the operation of the curia during the pontificates of Innocent VII, Gregory XII, Alexander V and John XXIII and the councils of Pisa and Constance. Finallyit it investigates the elaboration of a complete rhetorical model that served the papal propaganda. The socio-institutional dynamics and the ideological and ethical principles that served as the basis of a fruitful collaboration between humanism and papacy are highlighted, as well as ways of creating a memory and a common eloquence. This dissertation includes a series of additional annexes (prosopographical tables, typologies of rhetorical and diplomatic corpus, and editions of archival and literary documents)

Pełny tekst źródłaIn this dissertation we developed three main works in which adsorption phenomenon play a predominant role.According to the BP Statistical Review, Colombia’s reserves/production ratio is close to 12 and currently all the natural gas production comes from conventional reserves; meanwhile its unconventional technically recoverable gas reserves are about twelve times greater than conventional ones. Most of them are located in the Middle Magdalena Valley Sedimentary Basin (MMV). In this context we measured the methane adsorption capacity on five shale core samples obtained during exploratory drilling from three boreholes located in the MMV. The experiments were carried out at 50 and 75°C and for pressure ranging up to 3.5 MPa under dry conditions. The geochemical and structural characterizations were carried out in the Department of Geology of the Universidad Autonoma de Madrid. The effect of total organic carbon (TOC), thermal maturity, clay content and specific surface area (SSA) on methane adsorption capacity was studied. The results shows that the temperature has a negative effect on the adsorption capacity, while TOC has a positive effect, even if no linear regression was found between TOC and methane adsorption capacity. No correlation was observed between the clay content and the TOC-normalized adsorption capacity to methane, which indicates that clay minerals do not significantly contribute to methane adsorption in the case of our samples. In addition, there is not a general trend between TOC normalized and thermal maturity. Among the factors investigated in the present study, TOC has the major contribution to the adsorption uptake. A similar contribution is found for the SSA, which is consistent, considering the positive correlation between TOC and SSA. This set of data represents meaningful information for indirect estimations of the gas in place during the future recovery strategies. And maybe the most important, this study furthers the ongoing projects on the understanding of the adsorption effect on shale gas production and assessment.In addition to this work, we made a study on selective CH4/CO2 adsorption on a shale gas, which was previously characterized. The adsorption capacity and enthalpy of CO2 and CH4 pure at 50°C and for pressures up to 3.2 MPa were measured. Additionally, the equimolar mixture methane/carbon dioxide adsorption isotherms was performed up to 2 MPa at the same temperature. The results show that CO2 is preferentially adsorbed than methane, both in pure state as in the mixture. The estimated selectivity CO2/CH4 highlights a significant affinity of CO2 with the kerogen of this sample. These results are of great interest from an industrial point of view, because they mean that this shale could be a candidate for CO2 injection as recovery method; and for CO2 storage when it was depleted. Finally, having into account that separation and capture of CO2 have environmental connotations, we explored the separation of CO2 from an equimolar CH4/CO2 mixture using adsorbents of silica nanoparticles (natives and functionalized with amines) developed in the University of Vigo. We measured the adsorption capacity and enthalpy of CO2 and CH4 at 50°C and pressures up to 3MPa and the equimolar CH4/CO2 adsorption capacity at the same temperature and up to 2 MPa in both set of nanoparticles. The results showed that there is a preferential adsorption to CO2 over CH4 (in pure state and in the mixture), but CO2 adsorption is lower in native particles than in functionalized ones. However native particles are promising for CO2 capture. The value of selectivity of CO2 over CH4 is almost the same for both samples, it means that the functionalization process did not improve the performance of the particles in this case. This kind of works has a lot of perspective for the future

Pełny tekst źródłaHydrocarbons production from shales has been of growing industrial and scientific interest for the last fifteen years. The different kinds of shale resources represent huge quantities around the world and may durably change the energy market, as for example in the US. However, the recovery process remains critical and may drastically impact the profitability of these resources. In shales, the majority of the fluids are contained in micrometered nodules of organic matter : the kerogen, which acts as source rock and as reservoir for the oil and gas. The aim of the PhD thesis is to study the kerogen and the petroleum fluids contained in shales, by molecular simulations. For this purpose, Monte Carlo and Molecular Dynamics simulations with existing molecular simulation softwares and in-house codes have been used. The first part of the work has been dedicated to the construction of molecular models mimicking shales organic matter (kerogen and embedded fluids), based on analytical data. From these models, 3D structures have been generated under typical reservoir conditions. Agreements with available experimental results have been found on volumetric, storage, transport and mechanical properties. Then, we have focused our efforts on the adsorption and diffusion of hydrocarbon mixtures in such materials. Molecular simulations have been performed to provide both pseudo-experimental and reference data. On storage properties, a theoretical model which accounts for multicomponent adsorption of super-critical (dry gas) and sub-critical (condensate gas, light oil) mixtures has been developed and validated. On transport properties, the mechanisms governing hydrocarbon mass transfer have been identified and a model has been proposed which describes the dependence of mixture diffusion coefficients with thermodynamic conditions (composition, pressure and temperature)

Pełny tekst źródłaThe exploitation of natural unconventional resources in substitution for petroleum is one of the challenges of the 21st century. In situ microbial transformation of these resources in methane is one of the most promising pathway currently developed, although its application needs to be demonstrated. My objectives were to demonstrate the existence of a microbial conversion into methane of the organic matter (OM) of immature shales, and to quantify it in order to extrapolate the potential for methane production of the rocks at the sedimentary basin scale. A method of detection and monitoring of methanogenic consortia from paper shales in microcosms, combining quantitative PCR, GC-FID and Rock-Eval pyrolysis, was developed and validated. It was used to study the spatial distribution of methanogens in paper shales of the Paris Basin and to demonstrate the methanization of the OM of these rocks. The results show the conversion of the soluble fractions of the OM (bitumen) by methanogenic consortia isolated from shales, but also the transformation of a more complex fraction (kerogen). No strict correlation was established between lithology and presence of active methanogens, which makes the extrapolation of methane production to the basin scale more difficult. However, the localization of methanogens in both OM-rich and OM-poor zones constitute an advantage in the perspective of an economic exploitation of these resources. This work demonstrates a great potential for microbial methane production in the Paris Basin and paves the way to studies of economic feasibility and profitability on the scale of a production site

Pełny tekst źródłaWastewaters are often loaded in phosphate from human activities. The discharge of such wastewater without adequate treatment leads to rapid eutrophication of water bodies. The main of the present thesis was to characterize and investigate the removal efficiency of phosphate from water by natural geological material available in large amount in Ivory Coast. Ultimately, it has ambition to valorize geological material without mining interest for environmental purposes. For this research, the laterite, sandstone and shale were selected and prepared by mechanical crushing to obtain fine fractions below 80 µm. Detailed study to characterize these three rocks powder was performed, thus several mineralogical and physico-chemical properties were determinated by means of : X-ray diffraction (XRD), scanning electron microscopy (SEM), diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), N2-adsorption/desorption techniques (BET), energy dispersive x-ray spectroscopy (EDX), particle size distribution, cation exchange capacity and chemical analyses by atomic emission spectrometry (ICP-AES) and mass spectrometry (ICP-MS). Data shows high percentages of iron, aluminum and calcium oxides and oxyhydroxides for these three materials. This composition confer to the fine fraction the specific surface of 34; 4.7 et 16.5 m2/g for laterite, sandstone and shale respectively. In addition, the mineral structures of these materials reveal the presence of meso-and microporosity. These materials were then evaluated in the batch treatment of synthetic liquid effluents containing pure KH2PO4. The optimal dosage and equilibrium times were detected. After, isotherms were built at 20, 30 and 40°C. It was shown that phosphate affinity for the three absorbents is more important for laterite, sandstone and shale. The absorption process is strongly depends on pH. Phosphate retention rate on sandstone seem not to depend on temperature, on the other hand, those of laterite increase on the contrary way of the temperature and vice versa for schist. Several kinetic models (pseudo first order, pseudo second order, Elovich and diffusion models) were evaluated as well as thermodynamic parameters. Absorption reactions are perfectly described by the pseudo second order. Absorption equilibrium data allow defining interval where Langmuir and Freundlich model seems perfect. The proposed retention mechanism suggests the existence of two kinds of sites. DRIFTS analyses of adsorbents after adsorption revealed chemical interaction on adsorption process onto laterite and sandstone. This study demonstrated that laterite, sandstone and shale are an effective adsorbent for phosphate removal from aqueous solution. However, laterite shows a strong potentiality compared to the two others adsorbents
