The Problems of Sulphur discusses all aspects of the problems associated with sulfur in coal. The book is divided into three parts. Part 1 addresses the forms of sulfur in coal and evaluates processes directed at the chemical removal of sulphur. Part 2 expands on this to look at alternative means of removing sulfur both physically and biologically, sulfur removal during the combustion of coal and flue gas desulfurization processes. Part 3 looks at the role of sulphates in the atmosphere from the points of view of their formation, transport and deposition and of their effects on health, materials and the atmosphere. The book will be of value to engineers, environmentalists, and chemists.

All the guidance needed to test coal and analyze the results With the skyrocketing costs of most fuel sources, government, industry, and consumers are taking a greater interest in coal, an abundant and inexpensive alternative, which has been made more environmentally friendly through new technology. Published in response to this renewed interest, Handbook of Coal Analysis provides readers with everything they need to know about testing and analyzing coal. Moreover, it explains the meaning of test results and how these results can predict coal behavior and its corresponding environmental impact during use. The thorough coverage of coal analysis includes: * Detailed presentation of necessary standard tests and procedures * Explanation of coal behavior relative to its usage alongside the corresponding environmental issues * Coverage of nomenclature, terminology, sampling, and accuracy and precision of analysis * Step-by-step test method protocols for proximate analysis, ultimate analysis, mineral matter, physical and electrical properties, thermal properties, mechanical properties, spectroscopic properties, and solvent properties * Emphasis on relevant American Society for Testing and Materials (ASTM) standards and test methods, including corresponding International Organization for Standardization (ISO) and British Standards Institution (BSI) test method numbers To assist readers in understanding the material, a glossary of terms is provided. Each term is defined in straightforward language that enables readers to better grasp complex concepts and theory. References at the end of each chapter lead readers to more in-depth discussions of specialized topics. This is an essential reference for analytical chemists, process chemists, and engineers in the coal industry as well as other professionals and researchers who are looking to coal as a means to decrease dependence on foreign oil sources and devise more efficient, cleaner methods of energy production.

Trace Elements in Coal focuses on the compositions, reactions, and properties of trace elements in coal. The book first discusses the origin of trace elements in coal. The formation of peat; geological and geochemical aspects of coal seams; geology of Australian coals; constitution of coal; history of trace elements in coal; and coal mining in Australia are discussed. The text also clarifies the mode of occurrence of trace elements in coal. The identification of minerals in coal; silicon-rich minerals; carbonate minerals; sulfide minerals; lignites and brown coals; and phosphates are discussed. The book then underscores the methods of analysis. Inductively coupled plasma atomic emission spectrometry; atomic absorption spectrometry; spark source mass spectrometry; and neuron activation analysis are described. The text also focuses on the contents of trace elements in coal; comparisons of coal with shale and soil; relationship of radioactivity and coal; and relevance of trace elements in coal. The book is a good source of data for readers wanting to study the trace elements in coal.

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.

Here is the first volume to examine sulfur in fossil fuels from a geochemical perspective. It begins with six introductory chapters that present an overview of the material, historical background, and summaries of the present state of knowledge. Subsequent chapters cover: case studies of specific sedimentary environments; characterization of sulfur in selected coals and petroleums by various methods and techniques; and the major advances in understanding geochemistry at the molecular level. This important volume fills a significant gap in the technical literature and updates the understanding of the chemical processes in geological environments giving rise to sulfur fossil fuels.
