Book excerpt: Natural gas has gain popularity for transportation among other fuels since it is the cleanest burning fossil fuel. However, the important challenge for utilizing natural gas is its comparatively low volumetric energy storage density. Consequently, a suitable natural gas storage is needed. Adsorbed natural gas (ANG) is an interesting alternative because it could be expected to reduce the cost and potential damage from compressed natural gas (CNG) and liquefied natural gas (LNG) technology. Comparative adsorption of methane and carbon dioxide on activated carbon ZIF-8, UiO-66, and MIL-53 (Al) was investigated at 35 °C and up to 100 psi. The addition of PVDF in ZIF-8 and activated carbon were also studied including 75 wt% ZIF-8, 50 wt% ZIF-8, 25 wt% ZIF-8, 50 wt% ZIF-8, and 25 wt% ZIF-8. The result shows that the methane and carbon dioxide adsorption increase with the pressure. MIL-53 shows the highest methane and carbon dioxide adsorption. The high surface area and micropore volume corresponds to the high methane and carbon dioxide adsorption. However, the high micropore volume to total pore volume ratio also contributes to higher methane adsorption in the case of ZIF-8 and UiO-66. ZIF-8 has higher methane adsorption than UiO-66 although they have about the same surface area and micropore volume. On the contrary, UiO-66 has higher carbon dioxide adsorption than ZIF-8 affecting from chemical properties such as an open metal site and an organic ligand. Moreover, ZIF-8 has the highest CH4/CO2 selectively because it has high surface area, high micropore volume, high micropore volume to total pore volume ratio, and proper open metal site and organic ligand.

Available in PDF, EPUB and Kindle. Book excerpt: The work presented in this dissertation describes the design, synthesis, and characterization of metal-organic frameworks for applications in gas storage and gas separations, with a specific focus on natural gas and hydrogen storage for mobile applications and on post-combustion carbon dioxide capture from coal- or natural gas-fired power plants. A wide variety of techniques and spectroscopic methods are covered, including gas adsorption, x-ray diffraction, infrared and UV-vis-NIR spectroscopies, and calorimetry. Chapter One provides a brief introduction to metal-organic frameworks as a new class of porous materials for gas adsorption-related applications. The potential of metal-organic frameworks for use in post-combustion carbon dioxide capture and natural gas storage is discussed, and the unique and promising properties of adsorbents with stepped adsorption isotherms for these applications are highlighted. In Chapter Two, two representative metal-organic frameworks, Zn4O(BTB)2 (BTB3- = 1,3,5-benzenetribenzoate; MOF-177) and Mg2(dobdc) (dobdc4- = 1,4-dioxido-2,5-benzenedicarboxylate; Mg-MOF-74, CPO-27-Mg), are evaluated in detail for their potential use in post-combustion CO2 capture via temperature swing adsorption (TSA). Low-pressure single-component CO2 and N2 adsorption isotherms were measured every 10 °C from 20 to 200 °C, allowing the performance of each material to be analyzed precisely. In order to gain a more complete understanding of the separation phenomena and the thermodynamics of CO2 adsorption, the isotherms were analyzed using a variety of methods. These results show that the presence of strong CO2 adsorption sites is essential for a metal-organic framework to be of utility in post-combustion CO2 capture via a TSA process, and present a methodology for the evaluation of new metal-organic frameworks via analysis of single-component gas adsorption isotherms. Chapter Three briefly discusses high-pressure adsorption measurements and reviews efforts to develop metal-organic frameworks with high methane storage capacities. To illustrate the most important properties for evaluating adsorbents for natural gas storage and for designing a next generation of improved materials, six metal-organic frameworks and an activated carbon, with a range of surface areas, pore structures, and surface chemistries representative of the most promising adsorbents for methane storage, are evaluated in detail. High-pressure methane adsorption isotherms are used to compare gravimetric and volumetric capacities, isosteric heats of adsorption, and usable storage capacities. Additionally, the relative importance of increasing volumetric capacity, rather than gravimetric capacity, for extending the driving range of natural gas vehicles is highlighted. Other important systems-level factors, such as thermal management, mechanical properties, and the effects of impurities, are also considered, and potential materials synthesis contributions to improving performance in a complete adsorbed natural gas system are discussed. Chapter Four discusses the design and validation of a high-throughput multicomponent adsorption instrument that can measure equilibrium adsorption isotherms for mixtures of gases at conditions that are representative of an actual flue gas from a power plant. This instrument is used to study 15 different metal-organic frameworks, zeolites, mesoporous silicas, and activated carbons representative of the broad range of solid adsorbents that have received attention for CO2 capture. While the multicomponent results provide many interesting fundamental insights, only adsorbents functionalized with alkylamines are shown to have any significant CO2 capacity in the presence of N2 and H2O at equilibrium partial pressures similar to those expected in a carbon capture process. Most significantly, the amine-appended metal organic framework mmen-Mg2(dobpdc) (mmen = N,N′-dimethylethylenediamine, dobpdc4– = 4,4′-dioxido-3,3′-biphenyldicarboxylate) exhibits a record CO2 capacity of 4.2±0.2 mmol/g (16 wt %) at 0.1 bar and 40 °C in the presence of a high partial pressure of H2O. In Chapter Five, the flexible metal-organic frameworks M(bdp) (M = Fe, Co; bdp2– = 1,4-benzene-dipyrazolate) are shown to exhibit methane adsorption isotherms that feature a sharp step, giving rise to unprecedented performance characteristics for ambient temperature methane storage. Adsorption measurements combined with in situ powder X-ray diffraction and microcalorimetry experiments performed on Co(bdp) demonstrate a new approach to designing adsorbents for gas storage, wherein a reversible phase transition is used to achieve a high deliverable capacity while providing intrinsic thermal management. Importantly, the energy of the phase transition, together with the adsorption and desorption step pressures, can be controlled through variations in the framework structure, such as replacing Co with Fe, or by application of mechanical pressure. This approach overcomes many of the challenges to developing adsorbents for natural gas storage discussed in Chapter Three and is also relevant to other gas storage applications. Chapter Six discusses the synthesis and characterization of a new Ti(III) metal-organic framework that is constructed from 1,4-benzenedicarboxylate bridged Ti3O(COO)6 clusters. While many metal-organic frameworks have been synthesized with exposed divalent metal cations, there are comparatively few examples of metal-organic frameworks with coordinatively unsaturated trivalent metal centers. Among other potential applications, frameworks with exposed trivalent metal cations are of particular interest for ambient temperature H2 storage. Additionally, there are also very few reported titanium-based metal-organic frameworks and none that contain all titanium(III). Through a combination of adsorption measurements, diffraction analysis, EPR, infrared, and UV-vis-NIR spectroscopies, and magnetic measurements, this framework is shown to contain five-coordinate Ti3+ cations that irreversibly bind O2 to form titanium(IV)-superoxo and -peroxo species.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon Capture offers potential remediation for greenhouse gases from industrial point sources, and physical sorbents are an economically viable option, but one that requires optimisation. Here, materials were investigated to assess the effect of incorporation of functionalised ligands, which utilise a Lewis basic character, on the potential of such materials for Carbon Capture applications. Materials were investigated for their structural and adsorptive properties, allowing analysis and evaluation of the selective capture of carbon dioxide. Characterisation included single crystal X-ray diffraction, powder X-ray diffraction, infrared spectroscopy, thermogravimetric analysis, and elemental analysis. Adsorption properties were evaluated using volumetric nitrogen adsorption at 77 K, which showed all three materials experienced activated diffusion, and gravimetric carbon dioxide adsorption at 273 K. Further gravimetric adsorption analysis was performed at various temperatures using carbon dioxide, methane, and nitrogen gases, to analyse the performance of these materials under simulated conditions for carbon capture processes. Thermodynamic and kinetic properties were determined in order to provide an indication of the underlying processes governing diffusion and equilibration of adsorption.Three materials were investigated; Cu(bpetha)2SiF6 (bpetha = 1,2-bis(4-pyridyl)ethane), [Cu(TPT)]BF4.0.75H2O and [Cu(TPT)]NO3.MeOH (TPT = 1,3,5-tris(4-pyridyl)-2,4,6-triazine). Cu(bpetha)2SiF6 showed promising results for carbon dioxide adsorption (0.6 mmol g−1 at 100 kPa and 333 K), having kinetically selective behaviour for nitrogen and methane at timescales that are suitable for pressure swing adsorption processing (90 %/5 % of equilibrium uptake for carbon dioxide vs. nitrogen in under 3 min). The material also showed enhanced adsorption interactions towards carbonvdioxide as a consequence of electronegative fluorine atoms within the structure, and also exhibited flexibility of the framework towards carbon dioxide. [Cu(TPT)]BF4.0.75H2O showed poor adsorption capabilities for carbon dioxide (0.15 mmol g−1 at 100kPa and 333 K), which is ascribed to pore blocking effects of the anion within the structure. [Cu(TPT)]NO3.MeOH showed moderate uptakes for CO2 at low temperatures (1.96 mmol g−1 maximum capacity at 273 K), but demonstrated better adsorption capabilities for methane at higher temperatures (1.54 mmol g−1 at 100 kPa and 333 K). The framework experienced a large structural change upon adsorption, which was probed using methane at different temperatures.The results of this study showed that materials synthesised with inherent functionalisation could be developed to enhance carbon dioxide adsorption for Carbon Capture applications. However, other structural effects of the materials must be considered as the complexity of Metal-Organic Framework structures can influence the adsorption properties via a variety of mechanisms.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomethane is a proven source of clean energy, it is one of the most cost-effective and environment-friendly substitute for natural gas and diesel. The European Union primary energy production from biomethane has folded by ~23 times in a 5 years time period (2011-2016) making necessary to find new and improved solutions for the separation of methane (CH4) and carbon dioxide (CO2), main components of biogas. In this context, the objective of this doctoral thesis is the determination of performance indicators such as the adsorption capacity and selectivity of activated carbons (ACs) for the CH4/ CO2 separation. This work focuses on the adsorption properties of activated carbons for the methane/carbon dioxide separation. To this end, CH4 and CO2 pure gas experimental adsorption isotherms of activated carbons were obtained on a pressure range of 0.1 to 3 MPa) and temperatures ranging from 303 to 323 K. The first part of this thesis project consisted in the analysis of the CH4 and CO2 pure gas adsorption properties of 5 commercial activated carbons Using a set of five commercial activated carbons a linear relationship between the adsorbent surface area and the CO2 adsorption capacity was determined. The micropore volume also showed a direct influence on the adsorption capacity. The second part of this work consisted in the study of the carbon dioxide and methane adsorption behavior of biomass-based activated carbons. Using a series of 3 ACs that had been obtained from olive stones by different activation methods, the activation technique proved to be of mayor importance as it determines the textural and chemical properties of the adsorbent and thus its gas adsorption capacity.Lastly, the CH4/CO2 adsorption selectivity of the 5 commercial activated carbons was calculated from the equimolar mixture adsorption isotherms. The selectivity factor was proven to be dependent on the sum of textural and chemical properties of the samples. Although, activated carbons with high average pore sizes and surface areas depicted higher adsorbed quantities it was on detriment of their selectivity. The selectivity was found to be better for the activated carbon showing an intermediate surface area and a narrow pore size distribution. In addition, the presence of sulfur functionalities was also found to improve the adsorption selectivity. Overall, this work shows that activated carbons are competitive materials for the upgrading of biogas, displaying adsorption properties comparable to those of other commercially available materials.

This book was released on 2011-08-12 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science of statistical mechanics is concerned with defining the thermodynamic properties of a macroscopic sample in terms of the properties of the microscopic systems of which it is composed. The aim of this book is to provide a clear, logical, and self-contained treatment of equilibrium statistical mechanics starting from Boltzmann's two statistical assumptions, and to present a wide variety of applications to diverse physical assemblies. The coverage is enhanced and extended through an extensive set of accessible problems. An appendix provides an introduction to non-equilibrium statistical mechanics through the Boltzmann equation and its extensions. The book assumes introductory courses in classical and quantum mechanics, as well as familiarity with multi-variable calculus and the essentials of complex analysis. Some knowledge of thermodynamics is assumed, although the book starts with an appropriate review of that topic. The targeted audience is first-year graduate students, and advanced undergraduates, in physics, chemistry, and the related physical sciences. The goal of this text is to help the reader obtain a clear working knowledge of the very useful and powerful methods of equilibrium statistical mechanics and to enhance the understanding and appreciation of the more advanced texts.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of this program was to develop a low cost novel sorbent to remove carbon dioxide from flue gas and gasification streams in electric utilities. Porous materials named metal-organic frameworks (MOFs) were found to have good capacity and selectivity for the capture of carbon dioxide. Several materials from the initial set of reference MOFs showed extremely high CO2 adsorption capacities and very desirable linear isotherm shapes. Sample preparation occurred at a high level, with a new family of materials suitable for intellectual property protection prepared and characterized. Raman spectroscopy was shown to be useful for the facile characterization of MOF materials during adsorption and especially, desorption. Further, the development of a Raman spectroscopic-based method of determining binary adsorption isotherms was initiated. It was discovered that a stronger base functionality will need to be added to MOF linkers in order to enhance CO2 selectivity over other gases via a chemisorption mechanism. A concentrated effort was expended on being able to accurately predict CO2 selectivities and on the calculation of predicted MOF surface area values from first principles. A method of modeling hydrolysis on MOF materials that correlates with experimental data was developed and refined. Complimentary experimental data were recorded via utilization of a combinatorial chemistry heat treatment unit and high-throughput X-ray diffractometer. The three main Deliverables for the project, namely (a) a MOF for pre-combustion (e.g., IGCC) CO2 capture, (b) a MOF for post-combustion (flue gas) CO2 capture, and (c) an assessment of commercial potential for a MOF in the IGCC application, were completed. The key properties for MOFs to work in this application - high CO2 capacity, good adsorption/desorption rates, high adsorption selectivity for CO2 over other gases such as methane and nitrogen, high stability to contaminants, namely moisture, and easy regenerability, were all addressed during this program. As predicted at the start of the program, MOFs have high potential for CO2 capture in the IGCC and flue gas applications.
