Повний текст джерелаGiven the rapid increase in population and the growth in energy consumption as a consequence of major developments in transportation and technology, sustainable development is of special relevance, suggesting ways to mitigate greenhouse gases emissions, including carbon capture and storage (or utilization, CCSU), energy efficiency, alternative energy sources and energy savings, as already suggested by the Kyoto’s Protocol and the IPCC reports. Hence, much effort has been devoted in recent years to develop technologies for capture and storage of CO2 from concentrated sources of emission. Apart from establishing new technologies, over the last decades the science of porous solid materials has become one of the most intense areas of research and development for chemists, physicists, and materials scientists. In fact, considerable progress has been made in recent years on the development of novel adsorbents. For instance, Metal Organic Frameworks (MOFs) have been gaining considerable attention as promising nanoporous materials for gas storage and gas separation applications due to their exceptional physical and chemical properties, and have already been demonstrated to be promising materials in the separation of different gases, however, a molecular level understanding of gas adsorption in the pores is crucial to accelerate the design and development of these and other applications. It is also fundamental to know their behavior under moisture conditions and impurities content, as normally found at specific industrial applications. The work developed in this Thesis highlights the use of molecular simulation techniques for optimizing environmental related processes, providing new procedures to assess the use of these materials from their fundamental knowledge until their applications at industrial conditions. The overall objective is to advance in the field of materials for CO2 capture and separation at process conditions. The influence of water vapor and impurities is explicitly considered, both, in the light of the fundamentals of adsorption and in the application for post-combustion carbon dioxide capture by swing adsorption cycles. Starting from a brief description of the fundamentals of adsorption and molecular simulations, a novel throughout review on recent studies of materials for CO2 capture and separation is presented, thus providing valuable information to assess their industrial application. Based on this review, some of the most promising materials for CO2 separation in a Temperature Swing Adsorption (TSA) process have been studied in detail by using molecular simulations (compared to experimental data when available), proposing a new process for the evaluation and optimization capture systems under real conditions. In addition, given the great influence of water as a trace compound on the separation, CuBTC (one of the most studied MOFs, stable in water and with potential for industrial application) has been investigated in comparison to the benchmark zeolite 13X. The effect of the coexisting species as well as the influence of water and SO2 in flue gas is examined in detail in order to reach a better understanding of the adsorption capacity, selectivity, adsorption density location and isosteric heat distributions. And finally, detailed parametric studies have been carried out for a comparative computational investigation for separating of multi-component mixtures of flue gas by using other representative zeolites such as kaolinite and chabazite. Additional work, related to another environmental problem: the separation of a pollutant (ibuprofen) in water, by using activated carbons, is also presented here, demonstrating the versatility of the tools used for these types of systems.

Because of the toxicological relevance of pesticides introduced into the environment through agricultural practices, it is necessary to develop simple methodologies with low cost, enabling remove these pollutants from the environment, in particular of water intended for human consumption. The adsorption process is an efficient and low cost technique that have wide application. The adsorbent capacity of the leaves of Typha angustifolia L. herbaceous perennial plant belonging to the family Typhaceae, in Brazil it is also popularly known as taboa, was investigated for the removal of pesticides trifluralin, chlorpyrifos and α-endosulfan from aqueous medium. The the analytical method using solid phase extraction (SPE) and chromatography with electron capture detector (GC/ECD) was optimizates and validate. The validation criterions were reached and the analytical methos was considered efficient for trifluralin, chlorpyrifos and α-endosulfan quantification in an aqueous medium, providing credibility to the results obtained in the adsorption experiments. The adsorption capacity of T. angustifolia was evaluated under different parameters: treatment of the material, amount of material, contact time between the plant material and the pesticides solution and concentration of the pesticides solution. The results showed that treatment of the material with distilled water and was satisfactory and, for all doses evaluated the pesticide removal was efficient, with best results obtained at a dose of 3.0 g L-1 , equivalent to 60 mg of adsorbent in 20.0 mL of solution, in which the pesticide removal were between 73 and 80%. The adsorption kinetics of the pesticide by T. angustifolia showed that the adsorption equilibrium was reached in 40 minutes for all pesticides, removing up to 90% and using a very small amount of plant material (3 g L-1 ). The experimental data were evaluated using the kinetic models of pseudo-first order, pseudo-second order and Avrami. One of the limitations encountered in the concentration influence study is the limited solubility of the agrochemical in aqueous medium (between 0.33 and 1.00 mg L-1 ), resulting in the study of a small concentration range in the adsorption experiments. To study the pesticides adsorption mechanism by T. angustifolia material, the experimental data were applied to Langmuir, Freundlich and Sips non-linear isotherms models. Additional tests showed that the adsorption capacity is unaffected when using natural water in the adsorption experiments. The results indicate that the material obtained from of T. angustifolia leaves, has a great potential to be used as an alternative adsorbent material in pesticide contaminated aqueous solution treatment.
Devido à relevância toxicológica dos agrotóxicos introduzidos no ambiente através de práticas agrícolas, torna-se necessário o desenvolvimento de metodologias simples e de baixo custo, que permitam remover esses poluentes do meio ambiente, em especial, das águas destinadas a consumo humano. O processo de adsorção é uma técnica que possui grande aplicação, por ser eficiente e de baixo custo. A capacidade adsorvente das folhas de Typha angustifolia L., planta herbácea perene pertencente à família Typhaceae, no Brasil também conhecida popularmente como taboa, foi investigada para a remoção dos agrotóxicos trifluralina, clorpirifós e α-endossulfam de meio aquoso. Foi realizada a otimização e validação da metodologia analítica de extração em fase sólida (SPE) e determinação por cromatografia gasosa utilizando-se o detector por captura de elétrons (GC/ECD). A metodologia (SPEGC/ECD) atendeu aos critérios de validação estabelecidos e foi eficiente para a quantificação dos agrotóxicos em meio aquoso, fornecendo credibilidade aos resultados obtidos nos ensaios de adsorção. A capacidade de adsorção da T. angustifolia foi avaliada sob diferentes parâmetros: tratamento do material, dose de material, tempo de contato entre o material vegetal e a solução dos agrotóxicos e concentração dos agrotóxicos na solução. Os resultados obtidos mostraram que o tratamento do material com água destilada foi satisfatório e que para todas as doses de adsorvente avaliadas a remoção dos agrotóxicos foi eficiente, sendo obtido um melhor resultado para a dose de 3,0 g L-1 , equivalente a 60 mg de adsorvente para 20,00 mL de solução, onde se obteve remoção entre 73 e 80% dos agrotóxicos. O estudo cinético do processo de adsorção dos agrotóxicos pela T. angustifolia mostrou que o equilíbrio de adsorção foi alcançado em 40 minutos, para todos os agrotóxicos, com remoção de até 90%, utilizando uma dose muito pequena de material vegetal (3 g L-1 ). Os dados experimentais foram avaliados utilizando-se os modelos cinéticos de pseudo-primeira ordem, pseudo-segunda ordem e Avrami. Uma das limitações encontradas no estudo da influência da concentração foi a solubilidade limitada dos agrotóxicos em meio aquoso (entre 0,33 e 1,00 mg L-1 ), que fez com que os ensaios de adsorção fossem avaliados para uma pequena faixa de concentração. Para estudar o mecanismo de adsorção dos agrotóxicos pelo material T. angustifolia, os dados experimentais foram aplicados aos modelos não lineares de Langmuir, Freundlich e Sips. Ensaios adicionais mostraram que a capacidade de adsorção é pouco afetada quando se utiliza água natural obtida em represas nos ensaios de adsorção. Os resultados obtidos indicam que o material vegetal, obtido a partir das folhas de T. angustifolia, possui um grande potencial para ser utilizado como material adsorvente alternativo no tratamento de meio aquoso contaminado com os agrotóxicos trifluralina, clorpirifós e α-endossulfam.

Повний текст джерелаHistorically, porous silica (SiO2) is one of the most used adsorbents for a wide variety of processes in the industry. However, the fast grown on the demand of new nanotechnology based materials and sustainable green processes have made necessary the development of adsorbents with improved physico-chemical properties. One of the most applied options to modify porous silica is the incorporation on the surface of organic functional molecules, giving place to hybrid materials, in which the properties of both components are combined. In this doctoral thesis, supercritical carbon dioxide (scCO2) has been used as the solvent to carry out the functionalization processes. Carbon dioxide is a sustainable solvent and its use has been preferred in front of toxic organic liquid solvents, often applied in the traditional methods of synthesis. Amorphous silica matrices with structural ordered pores (MCM-41, 4 nm) and disordered pores (silica gel, 4-9 nm) were selected for the functionalization processes. Besides, the properties conferred by functionalization to microporous crystaline zeolites have been preliminary studied. The modifying agents applied in this thesis were either alkyl (octyltriethoxysialane) or amino (methylaminopropyltrimethoxisilane) silane and aziridine. The later compound is a monomer which polymerizes in presence of CO2, leading to hyperbranched polyethyleneimine (PEI) with multiple amino groups formed into the silica pores. This novel method only requires compressed CO2 as the reagent and the catalyst of the polymerization reaction of aziridine, which usually requires the use of organic solvents, a solid catalyst, high temperatures and long processing times. The functionalization of porous silica with aminosilane in scCO2 is more complex than the case of alkysilanes due to the high reactivity between amino groups and CO2 to form unsoluble carabamate species. However, in this study a protocol was designed to partially inhibit carabamate formation by controlling the pressure and temperature of the reaction media. The obtained materials were characterized using solid state characterization tools: low temperature N2 and CO2 adsorption, thermal analysis, infrared spectroscopy and X-Ray diffraction. Moreover, modeling and simulation methods were used as complementary tools that allowed the study of this complex systems with a high level of detail. The alkyl chain of the alkylsilane induced to the porous system a hydrophobic behavior, hence, obtaining materials candidates for oil adsorption. The functionalization with organic molecules containing the amino group allowed the preparation of materials for the adsorption and separation of CO2 from diluted gases (CO2 sequestration). The CO2 adsorption properties of the synthesized aminosilicas were evaluated combining experimental adsorption tools with molecular simulations. The characterization of these materials was based on the evaluation of the overall CO2 adsorption capacity and the influence of the temperature, the selectivity of the CO2 adsorption in gas mixtures, the stability in the cyclic adsorption/desorption process and the kinetics, which were determined by performing both microbalance and CO2 adsorption isotherms at different temperatures.

Повний текст джерелаScientific purpose of this doctoral dissertation is synthesis of functionalized two-dimensional materials (graphene and graphene oxide) and their comprehensive physicochemical characterization, with particular emphasis on adsorption and energy storage properties. We could demonstrate that covalent modification of graphene oxide (GO) with an organic polymer (BPEI) very favorably affects the efficiency of the adsorption process. The maximum adsorption capacity (qmax) values for heavy metal ions significantly favour this material in comparison to the majority of known carbon adsorbents. Moreover, functionalization of GO with mesoporous aminosilica (SiO2NH2) leads to obtaining an efficient and rapid adsorbent of organic cationic dyes (MB, RhB, MV). ln addition we proved that the functionalization of graphene (EEG) using the POM-surfactant su bu nits proved that this type of organic-inorganic hybrids material is very stable and have interesting electrical properties with potential application in the production of supercapacitors

Повний текст джерелаThe objective of this work was the measuring of adsorption equilibrium, by the gravimetric method. Experimental results are presented for the adsorption equilibrium of the series of n-alkanes, ethylene, nitrogen and carbon dioxide in two microporous materials, the metal-organic framework, MIL-53(Al) and zeolite 5A. Both of them have desirable characteristics for adsorption processes, such as the capture and storage of carbon dioxide, natural gas storage, separation of components of biogas, and separation of olefin/paraffin. The determination of the equilibrium of the pure components (ethane, propane, butane, ethylene, carbon dioxide and nitrogen) covers a wide range of thermodynamic conditions; temperatures between 303.15K and 373.15K, as well as pressure values between 0 and 50 bar. The adsorption equilibrium data were analyzed through the global adjustment for each adsorbate/adsorbent system, using the Sips and Toth models. The isosteric heat was also determined. The experimental data of methane, carbon dioxide and nitrogen were correlated successfully by the potential theory of adsorption collapsing into a single characteristic curve, independent of temperature. This analysis allows the extrapolation of adsorption data for other gases, for which no experimental data is still known. The adsorption capacity is generally higher in MIL-53(Al) than in zeolite 5A, and in the two adsorbents, the preferred adsorption capacity for carbon dioxide is a good indication that these materials have a strong potential in the capture and storage of carbon dioxide, in the purification of biogas or purification of methane from natural gas.

Повний текст джерелаMagnetite, also known as iron ferrite, is a mineral iron and a natural magnet found in iron deposits. In addition to its magnetic intrinsic behavior, the magnetite has the capacity to remove the metallic ions from aqueous medium by adsorption phenomena. The strong magnetic character of magnetite distinguishes it from other adsorbent types, which it allows to be readily removed from solution by magnetic separation. In this work, uranium (VI) adsorption, as UO22+ ions, from nitric solution by synthetic magnetite was investigated. It was prepared by simultaneous precipitation process, adding a NaOH solution into a solution containing Fe2+ and Fe3+ ions. The synthetic magnetite, a black powder, has exhibited a strong magnetic response in presence of a magnetic field, without nevertheless becomes magnetic. This typical superparamagnetic behavior was confirmed by magnetization measurements. Adsorption parameters of UO22+ ions such as pH. the adsorbent dose, contact time and equilibrium isotherm were evaluated. Maximum uranium adsorption was observed in the pH 4.0-5.0 range. It was noticed that increase in magnetite dose increased the percent removal of uranium, but decreased the adsorption capacity of the magnetite. It was observed from the relation between adsorption and contact time that the removal has increased very fast with time, and achieved the equilibrium within 30 minutes. The results of equilibrium isotherm agreed well with the Langmuir model, and so the theorical saturation capacity of the magnetite was determined for uranyl ions. The interaction between UO22+ ions and the magnetite was defined as a spontaneous chemical adsorption.

Повний текст джерелаVarious references on the use of ferrous compounds as non - conventional adsorption materials can be found in literature. According to the literature, such materials as hematite, galvanic slag and blast furnace slag were successfully used in liquid waste treatment for heavy metals removal. Thus, the use of abundant ferrous metallurgy slag may prove to be efficient for low cost treatment of liquid industrial waste. The main goal of the present work is the study of converter slag application as adsorber material for heavy metals removal from liquid waste. The present research was aimed at soluble copper ( Cu2+), nickel ( Ni2+ ) , cadmium ( Cd2+ ) , and lead (Pb2+) removal. These metals were chosen because of their high toxicity, and because they are considered as the most common pollutants present in liquid industrial waste. The obtained results on converter slag adsorption properties under optimized adsorption conditions show that 97,84 % of copper, 61,70 % of nickel, 87,22 % of cadmium and 96,20 % of lead can be removed from the liquid waste. The achieved adsorption rates are comparable to those of conventional adsorbers, and for soluble lead removal rates in the range of ( 92 - 115). 10 -3 mg g -1 min -1 were established. Additionally, if was shown that the investigated adsorption system presented spontaneous and endothermic behavior under conditions of activated adsorption with partial chemical adsorption characteristics. Such pattern is in good agreement with the models proposed by Langmuir and Freundlich for monolayer adsorption processes with adsorption centers having equal energy and specific heat of adsorption. Overall, the obtained results indicate the viability of the investigated material for commercial application.
