Book Description
When the properties of solid coal are compared with those of other common substances, coal seems in many ways unusual and mysterious. For example, almost any set of measurements of coal properties will exhibit time-dependent variation. This dynamic behaviour, commonly referred to as weathering, is known to affect adversely the physical and chemical properties which make coal valuable or desirable as an energy resource or basic material for the chemical industry. This book deals with the molecular-level origins of commonly observed time-dependent variations in the physical properties and chemical constitution of coal which are associated with the weathering process. Primary attention is devoted to the description of what are judged to be among the most important physical phenomena, their conceptual interpretation, and their relationships to various technical aspects of coal utilization, transport, and storage. The text is copiously referenced and indexed so as to make the material as accessible as possible. Chemistry of Coal Weathering is an ideal complement to standard textbooks dealing with coal science and technology, materials science, geochemistry and physical chemistry.

Book Description
An Introduction to Coal Technology provides an overview explaining what coal is, how it came into being, what its principal physical and chemical properties are, and how it is handled or processed for particular end uses. This book is divided into two parts; the first of which focuses on coal science and the second on technology. This volume is organized into 15 chapters and begins with a brief account of the origin, formation, and distribution of coal, along with its composition, classification, and most important properties. It then turns to beneficiation and handling; combustion; and various partial or complete conversion technologies. The final chapter deals with some aspects of pollution and pollution control. This book provides fairly detailed discussions on coal chemistry, including the molecular structure of coal. The challenges and limitations of coal technology are also considered. This book is intended for scientists and engineers who are active in other fields, but who might want to bring coal within the orbit of their interests, and to advanced students of chemical and mineral engineering who are contemplating careers in coal-related endeavors.

Book Description
Coal has been a major energy source for centuries. In 2021, coal provided around 28% of the total global primary energy requirements and 47% of the electricity demand. Coal also fuels around 80% of the world’s total iron and steel production. In spite of current global efforts to decarbonize the global environment by eliminating coal (the most polluting fossil fuel) all projections indicate that it will remain prominent in the global energy scene in the foreseeable future, filling about 21% of the primary energy demand and providing around 35% of electricity in 2040. Coal is also a precursor to many valuable gaseous and liquid fuels, premium chemicals and high-technology carbon materials. This book serves as an introduction to the extensive science and technology of coal, in particular, the properties which largely determine the utilization potentials of one of the world’s most valuable primary energy resources.

Book Description
Explores soil as a nexus for water, chemicals, and biologically coupled nutrient cycling Soil is a narrow but critically important zone on Earth's surface. It is the interface for water and carbon recycling from above and part of the cycling of sediment and rock from below. Hydrogeology, Chemical Weathering, and Soil Formation places chemical weathering and soil formation in its geological, climatological, biological and hydrological perspective. Volume highlights include: The evolution of soils over 3.25 billion years Basic processes contributing to soil formation How chemical weathering and soil formation relate to water and energy fluxes The role of pedogenesis in geomorphology Relationships between climate soils and biota Soils, aeolian deposits, and crusts as geologic dating tools Impacts of land-use change on soils The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals. Find out more about this book from this Q&A with the Editors
