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.

This volume is the product of a technical session organized for the 2002 Geological Society of America Annual Meeting in recognition of Isaac Kaplan's many contributions to various fields of geochemistry. As Kaplan enters his sixth decade of scientific investigation, it is fair to say that his work has touched or influenced innumerable scientists either directly or indirectly. Readers of this volume are presented with a collection of 29 papers written by former students, post-doctoral researchers, friends and colleagues from countries all over the world (including Sweden, Japan, Taiwan, New Zealand, Australia, Israel and the United States) from the fields of stable isotope, forensic, environmental and petroleum geochemistry, atmospheric chemistry and cosmochemistry.The stable isotope section includes papers investigating climate change, diagenesis, recent sediment and petroleum geochemistry and cosmochemistry problems. The forensic and environmental geochemistry section includes a variety of papers ranging from trace metals in soils to atmospheric CO2 projections. The petroleum geochemistry section includes both basic research and applied geochemistry papers. The ancient and recent sediments section contains papers ranging from carbon flux in modern sediments to Precambrian microfossils. All of the articles together cover a broad range of geochemical studies and represent the diverse and distinguished career of Isaac Kaplan.

Inorganic Geochemistry of Coal explains how to determine the concentrations and modes of occurrence of elements in coal, how to diminish adverse effects of toxic elements on the environment and human health, which elements in coal could be industrially utilized, and which elements can be successfully used as indications for deciphering depositional environments and tectonic evolution. As coal use will remain at an all-time high for the next several decades, there is a critical need for understanding the properties of this fuel to ensure efficient use, encourage its economic by-product potential, and to help minimize its negative technological, environmental and health impacts. - Features dozens of never-before published illustrations of critical features of the inorganic geochemistry of coal - Covers both the theory and applications of the topic, including case studies to serve as real-world examples - Includes a chapter on the health and environmental impacts of the mining, development and use of coal

This volume contains papers presented at the 30th International Geological Congress on coal. It includes information on the applications of high-resolution sequence stratigraphy to paralicand terrestrial coal-bearing strata and petrology and depositional environment of Early Jurassic coal.

Understanding the origin and fate of hydrocarbons in the subsurface was the major endeavor of organic geochemists during the second half of the twentieth century. They succeeded to the point where the deciphered interplaying of elements and processes paved the way for the revolutionary concept of the petroleum system, a unifying paradigm that plays an important role in decision making associated with oil and gas exploration. The chemistry and physics involved have been addressed in a quantitative way and integrated into the other aspects of petroleum geology, giving rise to the development of numerical basin modeling. This book has been designed to offer an overview of different aspects of the geochemistry of fossil fuels, in particular the functioning of a petroleum system. In this respect, it can be viewed as a foundation for approaching basin modeling. This book will be of interest to a large audience including specialists in the field, nonspecialist professionals, and undergraduate and graduate students.

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.
