Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The high energy density and abundance of coal along with the sustainability of biomass make them favorable fuels for energy production. However, the combustion of carbon-based fuels inevitably results in the production of the greenhouse gas carbon dioxide (CO2). To avert climate change and comply with likely future regulations for greenhouse gas emissions, the CO2 byproduct must be efficiently captured. Unfortunately, existing carbon capture methods result in significant decreases in plant efficiency and significant increases in capital and operating costs. The Coal-Direct Chemical Looping (CDCL) is an energy conversion process for coal/biomass that can separate the CO2 stream in-situ by utilizing iron oxide composite particles as oxygen carriers. Using this method, the iron oxide particles provide crucial oxygen to the coal instead of air, which is the key strategy to the process. The cycling of the iron oxide particles allows for efficient and total carbon capture, therefore ensuring the sustainability and economic viability of carbon-fueled power. Although biomass also produces CO2 upon combustion, it also absorbs CO2 as it is grown. Therefore, biomass can be utilized as a replacement for coal and further improve the sustainability of the process by making it carbon negative. The objective of this study is to investigate the enhancement of char and iron particle conversion with CO2, design a mechanism for particle transfer from the reducer to the combustor, and perform a preliminary assessment of the potential of biomass in the CDCL process. The main obstacle for CDCL is the conversion of coal char because the reaction between the metal oxide and the char is a slow solid-solid reaction. CO2 was found to help gasify the char and significantly increase the rate of reaction. In fact, in the experiments performed in this study, the addition of CO2 increased the amount of char reacted twofold. Furthermore, mixtures between 50% and 70% metal oxide with char were found to increase the char conversion the most compared to other mixtures. These mixtures increased the amount of char reacted 2-5 times, depending on the type of coal used. Ease of coal fluidization was found to be independent of the amount of metal oxide particles; however addition of 80-100% by mass of an inert particle was required in order to fluidize the biomass. A cold model of the reactor was constructed in order to study the gas-solid hydrodynamics and to design the most controllable method of handling solid fuels and oxygen carriers in the system. A design with high resistance and constant flow was selected based on experiments performed on the cold model. The results obtained by this study prove the capabilities of the CDCL process and will allow it to continue towards the scale up to a sub-pilot demonstration.

Book excerpt: Chemical Looping Combustion (CLC) is one promising fuel-combustion technology, which can facilitate economic CO2 capture in coal-fired power plants. It employs the oxidation/reduction characteristics of a metal, or oxygen carrier, and its oxide, the oxidizing gas (typically air) and the fuel source may be kept separate. This topical report discusses the results of four complementary efforts: (5.1) the development of process and economic models to optimize important design considerations, such as oxygen carrier circulation rate, temperature, residence time; (5.2) the development of high-performance simulation capabilities for fluidized beds and the collection, parameter identification, and preliminary verification/uncertainty quantification; (5.3) the exploration of operating characteristics in the laboratoryscale bubbling bed reactor, with a focus on the oxygen carrier performance, including reactivity, oxygen carrying capacity, attrition resistance, resistance to deactivation, cost and availability; and (5.4) the identification of kinetic data for copper-based oxygen carriers as well as the development and analysis of supported copper oxygen carrier material. Subtask 5.1 focused on the development of kinetic expressions for the Chemical Looping with Oxygen Uncoupling (CLOU) process and validating them with reported literature data. The kinetic expressions were incorporated into a process model for determination of reactor size and oxygen carrier circulation for the CLOU process using ASPEN PLUS. An ASPEN PLUS process model was also developed using literature data for the CLC process employing an iron-based oxygen carrier, and the results of the process model have been utilized to perform a relative economic comparison. In Subtask 5.2, the investigators studied the trade-off between modeling approaches and available simulations tools. They quantified uncertainty in the high-performance computing (HPC) simulation tools for CLC bed applications. Furthermore, they performed a sensitivity analysis for velocity, height and polydispersity and compared results against literature data for experimental studies of CLC beds with no reaction. Finally, they present an optimization space using simple non-reactive configurations. In Subtask 5.3, through a series of experimental studies, behavior of a variety of oxygen carriers with different loadings and manufacturing techniques was evaluated under both oxidizing and reducing conditions. The influences of temperature, degree of carrier conversion and thermodynamic driving force resulting from the difference between equilibrium and system O2 partial pressures were evaluated through several experimental campaigns, and generalized models accounting for these influences were developed to describe oxidation and oxygen release. Conversion of three solid fuels with widely ranging reactivities was studied in a small fluidized bed system, and all but the least reactive fuel (petcoke) were rapidly converted by oxygen liberated from the CLOU carrier. Attrition propensity of a variety of carriers was also studied, and the carriers produced by freeze granulation or impregnation of preformed substrates displayed the lowest rates of attrition. Subtask 5.4 focused on gathering kinetic data for a copper-based oxygen carrier to assist with modeling of a functioning chemical looping reactor. The kinetics team was also responsible for the development and analysis of supported copper oxygen carrier material.

This book was released on 2015 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast reserves of Victorian brown coal (VBC), over 400 years at the current rate of consumption, is predominantly used for power generation with over 80% of Victoria's electricity generated from the combustion of this fuel. This results in the emission of vast amounts of greenhouse gases such as CO2. Hence, it is important to investigate carbon dioxide capture and storage technologies for use in power stations employing fossil fuels. Chemical Looping Combustion (CLC) is an emerging CO2 capture technology which is capable of inherently capturing CO2. In CLC, the Oxygen Carrier (OC) provides the oxygen for the combustion of the fuel hence eliminating dilution with N2 from air. Once the oxygen in the OC is depleted, it is regenerated through oxidation in air and is then sent back to react with another batch of fuel. The vast majority of research in the field of CLC has been focussed on gaseous fuels such as natural gas and syngas due to the simplicity of such a process. In recent times, there has been a shift towards the use of solid fuels due to their abundance, widespread availability and lower cost. As such, there are a number of gaps in the field of CLC employing solid fuels; additionally, the only information relating to CLC of VBC is limited to experiments using small scale laboratory equipment. This thesis serves to fill some of the gaps in the field of VBC-fuelled CLC. The first study investigated the effect of inherent coal minerals on the performance of a CLC system; a high ash Canadian lignite was also used as part of this comparative study. The results highlighted that the low ash VBC was more suitable for use as a fuel in CLC as it was highly reactive and its low ash content led to a smaller amount of ash deposition on the OC. The second study involved using synchrotron radiation to perform in-situ X-ray Diffraction studies of a VBC-fuelled CLC process to understand both the changes that the OC undergoes as part of the redox reaction as well as carbon deposition on the OC. The results showed that the reduction of Fe2O3 beyond Fe3O4 was not favourable over long periods of time when using CO2 as the gasification agent as it led to carbon deposition on the OC. The third study is a first-of-its-kind investigation, where the reduction kinetics of an Fe-based OC was determined in the presence of a char derived from VBC. The Shrinking Core Model (SCM) and the Modified Volume Reaction Model (MVRM) were used to model the reduction of the OC. The results showed that both models were capable of predicting the reduction of Fe2O3 in the presence of a solid fuel. The calculations also verified that the rate limiting step in CLC was that of char gasification. The fourth study investigated the effect of the reactor configuration on the performance of the CLC system as such a comparison has never been attempted. A fluidized bed reactor, an atmospheric fixed bed reactor and a pressurized fixed bed reactor operated at 5 bar were used. The amount of the fuel and the OC together with the flow rates of the gases were kept constant so that the results from the different setups could be compared accurately. It was found that using the fluidized bed reactor allowed for the fastest gasification of the fuel due to better contact between the gasification agent and fuel. Although the CO2 yield and carbon conversion in the fluidized bed reactor was lower compared to the other two fixed bed reactors, it is expected that the use of a circulating fluidized bed (CFB) reactor with cyclones, a carbon stripper and a taller expanded freeboard would improve these two parameters. The fifth study involved fabricating and trialling 18 synthetic OCs in which NiO, CuO and Mn2O3 were supported on Fe2O3. This was done as most studies in literature utilize an inert support that is not able to take part in the redox reaction; as such a greater quantity of the OC is needed to provide the necessary oxygen. The results highlight that impregnated OCs were more reactive relative to their physically mixed counterparts. The use of high levels of CuO should be avoided as it led to the defluidization of the bed. Although NiO performed well, it may not be suitable for use due to its toxicity. Taking numerous considerations into account, the use of Mn2O3 was recommended as it led to a synergistic effect with Fe2O3. The sixth and final study of this thesis utilized a 10 kWth alternating fluidized bed reactor to trial the performance of VBC in a large scale reactor. A number of studies on the effects of temperature, fuel type, OC particle size range and long term operation on the performance of the CLC system were done. The NOx emissions were quantified and a carbon balance was also performed. The NOx emissions were found to average around 25 ppm over the course of the reduction reaction. Based on the carbon balance, 6.8% of the introduced carbon was unaccounted for due to the low capture efficiency of the cyclones. The optimum parameters were found to be 900°C for the temperature, 150-350 μm for the OC particle size range and VBC for the fuel. The average carbon conversion and CO2 yield over 35 reduction reactions was found to be 86% and 81% respectively for the conditions optimized for this reactor setup. These studies show that the use of Fe-based OCs is highly promising with VBC. The main recommendation from this thesis is the use of VBC in a CFB reactor as this is expected to significantly improve the carbon conversion and CO2 yield.

Book excerpt: Excerpt from A Text-Book of Inorganic Chemistry for University Students Limitations of space prevented more than a bare mention of most of the so-called Rare Elements, many of which are now Of great importance in chemical industry and form part of articles familiar in everyday life. Their chemical properties are also in many cases of unusual interest. A short account of Werner's theory is given, since the classical theory Of Valency, which is of fundamental importance in the somewhat monotonous uniformity Of the chemistry of carbon, proves inadequate when any but the very simplest compounds of the remaining elements are under consideration. The last chapter is intended to be no more than an outline' greater detail in this field would have been inconsistent with the scope of the book, and even undesirable in the present somewhat mobile state of the frontiers of this new knowledge.

Book excerpt: This book presents the current carbonaceous fuel conversion technologies based on chemical looping concepts in the context of traditional or conventional technologies. The key features of the chemical looping processes, their ability to generate a sequestration-ready CO2 stream, are thoroughly discussed. Chapter 2 is devoted entirely to the performance of particles in chemical looping technology and covers the subjects of solid particle design, synthesis, properties, and reactive characteristics. The looping processes can be applied for combustion and/or gasification of carbon-based material such as coal, natural gas, petroleum coke, and biomass directly or indirectly for steam, syngas, hydrogen, chemicals, electricity, and liquid fuels production. Details of the energy conversion efficiency and the economics of these looping processes for combustion and gasification applications in contrast to those of the conventional processes are given in Chapters 3, 4, and 5.Finally, Chapter 6 presents additional chemical looping applications that are potentially beneficial, including those for H2 storage and onboard H2 production, CO2 capture in combustion flue gas, power generation using fuel cell, steam-methane reforming, tar sand digestion, and chemicals and liquid fuel production. A CD is appended to this book that contains the chemical looping simulation files and the simulation results based on the ASPEN Plus software for such reactors as gasifier, reducer, oxidizer and combustor, and for such processes as conventional gasification processes, Syngas Chemical Looping Process, Calcium Looping Process, and Carbonation-Calcination Reaction (CCR) Process.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With the rising concern of climate change, extensive research has been conducted in recent years on the mitigation of global warming. Greenhouse gas emissions are considered as the key driver of global warming. Among the various greenhouse gases, CO2 is the major contributor to the greenhouse effect. Therefore, mitigation of CO2 emission is the key to address global warming. Chemical looping is an energy conversion technology that can directly produce a concentrated CO2 stream, ready for sequestration and utilization, without the need for an individual CO2 separation step, and thus, has the potential to drastically reduce the energy consumption and cost associated with CO2 capture in carbonaceous fuel energy conversion systems. In this dissertation, process modeling and analysis are conducted on solid fuel power production processes to quantify the energy penalty and exergy losses associated with CO2 capture technologies, including state-of-the-art solvent-based CO2 absorption, oxy-combustion using high purity oxygen, and chemical looping combustion technology. Following the comparison of various power production processes using solid fuel with and without CO2 capture, a comprehensive analysis is performed to investigate the effect of varying operation conditions on the performance of chemical looping combustion reactor system. The coal-direct chemical looping process is a chemical looping combustion technology using moving bed reducer configuration that can directly use coal as the feedstock without requiring upstream gasification steps. An integrated 250 kWth coal-direct chemical looping pilot unit using iron-based oxygen carriers has been constructed and demonstrated for long-term continuous operations. The principles for the design and operation of the primary reactor system are discussed in this dissertation. The results of a successful 288-hour continuous demonstration with pulverized bituminous coal are reported. The results from the pilot unit highlight the concept of the chemical looping combustion process as a promising solid fuel combustion technology with CO2 capture. To investigate chemical looping technology for hydrogen production, process simulation and analysis is performed on two distinct configurations for chemical looping H2 generation process. The simulation results of two chemical looping H2 generation configurations are compared with the conventional steam-methane reforming system to underscore the attractiveness of the chemical looping configurations.

Available in PDF, EPUB and Kindle. Book excerpt: This book considers the pollutants formed by the combustion of solid biomass fuels. The availability and potential use of solid biofuels is first discussed because this is the key to the development of biomass as a source of energy. This is followed by details of the methods used for characterisation of biomass and their classification. The various steps in the combustion mechanisms are given together with a compilation of the kinetic data. The chemical mechanisms for the formation of the pollutants: NOx, smoke and unburned hydrocarbons, SOx, Cl compounds, and particulate metal aerosols are given in detail. Combustion kinetics required for the application for design purposes are given. Examples are given of emission levels of a range different types of combustion equipment. Data is given of NOx, particulates and other pollutant arising from combustion of different fuels in fixed bed combustion, fluidized bed combustion and pulverised biomass combustion and co-firing. Modeling methods including computational fluid dynamics for the various pollutants are outlined. The consequential issues arising from the wide scale use of biomass and future trends are then discussed. In particular the role of carbon capture and storage in large biomass combustion plants is considered as well as the opportunity of reducing the concentration of atmospheric concentration of carbon dioxide.

Available in PDF, EPUB and Kindle. Book excerpt: Since the late 1970s there has been an explosion of industrial and academic interest in circulating fluidized beds. In part, the attention has arisen due to the environmental advantages associated with CFB (circulating . fluidized bed) combustion systems, the incorporation of riser reactors employing cir culating fluidized bed technology in petroleum refineries for fluid catalytic cracking and, to a lesser extent, the successes of CFB technology for calcina tion reactions and Fischer-Tropsch synthesis. In part, it was also the case that too much attention had been devoted to bubbling fluidized beds and it was time to move on to more complex and more advantageous regime,S of operation. Since 1980 a number of CFB processes have been commercialized. There have been five successful International Circulating Fluidized Bed Confer ences beginning in 1985, the most recent taking place in Beijing in May 1996. In addition, we have witnessed a host of other papers on CFB funda mentals and applications in journals and other archival publications. There have also been several review papers and books on specific CFB topics. However, there has been no comprehensive book reviewing the field and attempting to provide an overview of both fundamentals and applications. The purpose of this book is to fill this vacuum.
