Book Description
Coal Science, Volume 3 presents and evaluates selected fundamental scientific areas on coal structure, reactivity, and utilization. This book describes the organic geochemistry of coal, role of oxygen functionality in coal and coal liquids reactivity, chemistry of hydrocarbon syntheses from carbon monoxide and hydrogen, and chemistry of coal in carbon monoxide/water systems. Other topics discussed include intermediates and mechanisms of the FTS of hydrocarbons; synthesis of oxygenates; and structural features of vitrinite macerals. The molecular weight determination for coal derivatives; thermal reactions of oxygen compounds; and alternative methods for removing oxygen compounds from coal-derived liquids are also elaborated. This publication likewise covers the aqueous coal conversions and conversion mechanism. This volume serves as a valuable source of information and guide to scientists and researchers interested in the coal literature.

Book Description
Coal Science, Volume 1 presents and evaluates the fundamental scientific areas involved with the structure, reactivity, and utilization of coal. This book reviews the coal's inorganic structure and reactivity and the role that ionic bonding plays in coal's chemical and physical structure and reactivity. Organized into five chapters, this volume begins with an overview of the characteristics of coals that are attributable to plastic substances. This text then examines coal's organic components that are derived from complex plant materials by complicated biological and chemical reaction processes. Other chapters consider the valuable tools in coal research, including electron spin resonance and nuclear magnetic resonance. This book discusses as well the problem of determining the molecular structure of the organic part of coal. The final chapter deals with the reductive alkylation reaction and other pertinent procedures such as reduction without alkylation and alkylation without reduction. This book is a valuable resource for chemists, engineers, and research workers.

Book Description
Report on the oxidation of coal using two surface-sensitive spectroscopic techniques: Secondary Ion Mass Spectrometry (SIMS) and X-ray Photoelectron Spectroscopy (XPS). This report focuses on aspects of coal surface chemistry which can lead to increased intake of oxygen. This has been studied using isotopically-labelled oxygen as well as specific reagent groups which react uniquely with certain chemical sites on a surface. SIMS imaging was used to identify specific microscopic regions of the coal where reactions occurred, and to correlate the interaction of surface regions containing different elements or functional goups and XPS chemical shifts were used to follow the chemistry of carbon, sulphur, oxygen, iron and other elements as a function of oxidation.

Book Description
In this book, specialists from a variety of disciplines address the vast and complex subject of the chemistry of coal. The book comprises two parts: the first consists of seven review articles on coal chemistry, including NMR, tandem mass spectrometry, physics, liquefaction, catalytic reactions, devolatilization and combustion. Of particular interest in this part, is the frequent inclusion in many of the contributions of the authors' own research results, hitherto unpublished elsewhere. Good examples of this are the work on magnetic susceptibility of coal (a new branch of coal physics) and the article on tandem mass spectrometry (a new branch of analytical chemistry of coal). The second part contains twelve original articles covering characterization and chemistry of coal, structure and depolymerization, analytical methods including gas chromatography, mass spectrometry, gas-liquid chromatography, size-exclusion chromatography and analysis of oxygen by fast-neutron activation. Physical chemistry and physical properties of coal are dealt with in articles on coal slurry electrolysis, oxidation, thermal decomposition, absorption and diffusion.
