To stay profitable while complying with environmental regulations requires that the coal industry not only improve fine coal recovery but also finds better ways for its utilization. This is the first monograph on the processing of fine coal which recognizes that all unit operations that handle fine coal depend on coal surface properties, and which in one single volume provides a comprehensive introduction to coal surface chemistry, using it rigorously in treating coal flotation fundamentals and engineering, fine coal manipulation, pelletization and briquetting, and coal-water slurries. Readers involved in mineral processing, chemical engineering, mining and metallurgical engineering; technical personnel working for reagent suppliers; and scientists researching the field of coal surface chemistry, flotation and fine coal utilization will find this volume of great interest.

Updating content from the author’s 2001 book Coal Desulfurization, this new title focuses on CO2 sequestration and utilization. It includes information on the theory and practical approaches to CO2 capture and recent advances in the use of sequestered CO2. Avoiding these pollutants requires either forgetting about the 250 billion tons of coal reserves the United States possesses or capturing and utilizing the pollutants in a profitable and environmentally responsible fashion. The book covers postcombustion and precombustion capture approaches for coal, and postcombustion capture can be generalized to many other fuels. Recent practical implementations at full-scale power facilities around the world are discussed. The book covers sequestering CO2 via underground, oceanic, biological, and other long-term CO2 storage methods. It also includes recent advances in utilizing CO2 for enhanced oil recovery, advances in storage with depleted oil and gas reservoirs and deep saline aquifers, and additional topics. The book also examines specific applications of pure CO2 and covers chemical conversion of CO2 to useful compounds. It answers questions like "Can we create methanol from coal?" or "Can we create ethanol from coal?" It is found that methanol and ethanol cannot be sustainably produced from coal power alone. However, oxalic acid can be created at a much lower energy cost than methanol or ethanol. Oxalic acid can be used to extract rare earths, which are not currently produced anywhere in the United States, but are typically concentrated in coal ash. Aimed at researchers and industry professionals in chemical, environmental, and energy engineering, this book provides insight and inspiration into capturing CO2 not merely as a response to regulatory pressure and climate change but as an inherently profitable and valuable venture.
This book gathers technical and scientific articles by leading experts from 15 countries and originally presented at the world’s most prestigious forum on coal preparation: the XVIII International Coal Preparation Congress. Topics addressed include: the mineral resources basis of the coal industry; problems and prospects of development in the coal industry; crushing, grinding, screening and classification processes used at sorting plants; coal processing and briquette factories; review of plant designs and operations used around the world; new developments in dense-medium separators, water-based separation processes, froth flotation and dewatering; technologies and equipment for the dry separation of coal; coal deep processing technologies and equipment; energy generation as an area of coal deep processing; and simulation and optimization software for separation processes.In general, the future of coal around the world is defined by its competitiveness. As the cheapest form of fuel (comparatively speaking), coal undoubtedly continues to be in high demand around the world.
This book was written to provide a comprehensive survey of the current state-of-the-art information in coal preparation, with particular emphasis on coal desulfrization. The primary audience for this book will be practising coal preparation engineers who need complete information about all of the coal preparation and desulphurization technologies that are available now, or that may be available in the future. It will also be valuable for coal researchers who need details and comparative data for cutting-edge technologies that are still under development. The main emphasis is on physical coal preparation, but chapters also include chemical and biological technologies that are under development, but not yet used in industrial practice. Along with the successful technologies, also included are details of processes and techniques that were attempted, but were subsequently abandoned, along with discussions of the reasons they were abandoned.
As the demand for global energy increases, fact-based evaluations of alternative energy sources are needed in order to address the growing interest in how energy is produced, provided, and transported in sustainable ways. Future Energy, Second Edition provides scientists and decision makers with the knowledge they need to understand the relative importance and magnitude of various energy production methods in order to make the energy decisions needed for sustaining development and dealing with climate change. The second edition of Future Energy looks at the present energy situation and extrapolates to future scenarios related to global warming and the increase of carbon dioxide and other greenhouse gases in the atmosphere. This thoroughly revised and updated edition contains over 30 chapters on all aspects of future energy, each chapter updated and expanded by expert scientists and engineers in their respective fields providing an unbiased and balanced view of the future of energy. - Provides readers with an up-to-date overview of available energy options, both traditional and renewable, as well as the necessary tools to make informed decisions regarding selection, use, and environmental impacts. - Covers a wide spectrum of future energy resources presented in a single book with chapters written by experts of the particular field - Eleven new chapters including chapters on: solar heating, energy resources in developing nations and frontiers in oil and gas, Arctic drilling and unconventional oil and gas sources, thorium in nuclear fission, ethanol and other options for future transport fuel, fracking, smart grids, new batteries, environmental issues and the energy options for China
