This book is broadly divided into two sections. A number of main themes are discussed in the first section, 'Chemical Structure and Thermoplastic Properties of Coal', covering such topics as the relationships between the chemical structures of coals and thermoplastic phenomena under heating, studies of higher-ordered agglutination structure of coals, kinetic analyses of thermal decomposition reactions, oxidation and dilatation/contraction of coal particles, and formation mechanisms of coke structure. In the second section, 'Simulation of Coal Pyrolysis and Coke Formation', mathematical formulation models are presented to show thermoplastic phenomena of coals, strengths of produced coke, and phenomena observed when heating coal particles in packed beds.

Coal Structure deals with the structure, mineral and organic components, and the physical and chemical properties of coal. The book is composed of papers that present a detailed and coherent description of both the physical and chemical structure of coal and the effect of coal structural features on coal processing. The contributions in the text discuss such topics as coal macerals, coal porosity, aromaticity, functional groups and heteroatoms in coal, polymer structure of coal, and mineral matter in coal. Engineers, researchers, scientists, and management personnel who are directly involved in the study and processing of coal will find the book a well-rounded reference source.

The coals used in the present study were first crushed to -60 mesh, then evaluated for thermoplastic characteristics and extracted with specific solvents (N,N-dimethylformamide and pyridine). The resulting 'bitumen' extract was separated analytically by high performance liquid chromatography in "reverse phase" and "size exclusion" (SEC) modes. Reverse phase HPLC was used to separate components of pyridine and DMF extracts according to polarity. SEC was used to study the molecular weight of the extracts. Swelling experiments were performed to examine variation of the relative crosslink density of the samples. Data obtained from these experiments and from analysis supplied with the coals have been evaluated with the data from thermoplasticity determinations in order to examine some relationships of coal structure and thermoplasticity.

This book provides insights into the development and usage of coal in chemical engineering. The reactivity of coal in processes such as pyrolysis, gasification, liquefaction, combustion and swelling is related to its structural properties. Using experimental findings and theoretical analysis, the book comprehensively answers three crucial issues that are fundamental to the optimization of coal chemical conversions: What is the structure of coal? How does the underlying structure determine the reactivity of different types of coal? How does the structure of coal alter during coal conversion? This book will be of interest to both individual readers and institutions involved in teaching and research into chemical engineering and energy conversion technologies. It is aimed at advanced- level undergraduate students. The text is suitable for readers with a basic knowledge of chemistry, such as first-year undergraduate general science students. Higher-level students with an in-depth understanding of the chemistry of coal will also benefit from the book. It will provide a useful reference resource for students and university-level teachers, as well as practicing engineers.

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
