Analytical Methods for Coal and Coal Products, Volume I presents the analytical problems and methods for coal and its numerous products. This book discusses the technological importance of the measurement of the physical properties of coal. Organized into four parts encompassing 19 chapters, this volume starts with an overview of the petrographic analysis of coal wherein it involves two distinctive methods, namely, the reflected light and the transmitted light techniques. This text then discusses the means and methods of reflectance determination and proceeds to outline some of the results obtained and conclusions derived from them about the nature of coal. Other chapters explain the mechanical properties of coal, which are measured in order to predict its behavior in coal mines, coal winning, coal storage, coal comminution, coal handling, briquetting and agglomeration, and several other situations. The final chapter deals with the characterization of the liquid products of coal conversion. This book is a valuable resource for engineers, scientists, chemists, and researchers.
This volume concerns sources of polycyclic aromatic hydrocarbons (PAH), their emission factors, and relative importance. It deals with exposure, uptake, metabolism, and detection of PAH in the human body. The volume contains an update of information in environmental and biochemical studies of PAH.
This book contains contributions based on the proceedings of two symposia on food contamination held in London in April 1989 and May 1990, both of which were organised jointly by the Environment, Food Chemistry and Toxicology Groups of the Royal Society of Chemistry. The aim of these meetings was to assess the extraneous chemical contamination of food from two sources: firstly, food-chain contaminants - the presence of plant toxicants of fungal metabolites in food, or the contamination of food from environmental sources (airborne, aquatic and terrestrial); and secondly, food-production contaminants - contaminants of man-made origin brought about by a desire to facilitate food production and ...
Electrokinetic Phenomena emphasizes the impact of methods such as capillary zone electrophoresis, capillary electrochromatography, and capillary gel electrophoresis on the analysis of biomolecules. This reference reveals the electrokinetic phenomena that underlie high-performance electro-based analytical tools and vividly depicts how electro
Analytical Methods for Coal and Coal Products, Volume II, aims to provide a detailed presentation of what constitutes the first comprehensive reference work devoted exclusively to the subject of analytical methodology for coal and coal products. The various chapters have been arranged according to either a specific coal process or a specific coal use problem. The topics discussed include the structure of coal and coal products, minerals in coal, coal carbonization products, and coal combustion products. The general philosophy of this work is to strike a balance between sophisticated analyses based on expensive instrumentation such as mass or nuclear magnetic resonance spectrometers, and the more common, less expensive equipment typically employed in the standard methods. Likewise there is an attempt to strike a balance between the expertise available from within the United States and that found in other countries, offering a broader viewpoint. Altogether, a large number of cross references have been entered in these chapters to enable the reader to make maximum use of pertinent information in all of the chapters.
Leading researchers discuss the past and present of chromatography More than one hundred years after Mikhail Tswett pioneered adsorption chromatography, his separation technique has developed into an important branch of scientific study. Providing a full portrait of the discipline, Chromatography: A Science of Discovery bridges the gap between early, twentieth-century chromatography and the cutting edge of today’s research. Featuring contributions from more than fifty award-winning chromatographers, Chromatography offers a multifaceted look at the development and maturation of this field into its current state, as well as its importance across various scientific endeavors. The coverage inc...
This book explores the fundamental and practical aspects of supercritical fluid chromatography (SFC) and extraction. It discusses packed columns in SFC; detection in SFC; supercritical fluid chromatography/mass spectroscopy; and evaporative light scattering detection in SFC.
The past decade has witnessed major advances in our understanding of the chemical composition, structure, and reactivity of the complex organic-rich fossil matter known as "coal. " Nevertheless, important scientific questions concerning molecular weight distributions, degree of crosslinking, typical duster sizes, type of interconnecting bridges, the possible role of a "mobile phase," and the nature of organic sulfur forms remain topics of heated debate. Moreover, there appears to be a notable lack of consensus regarding the overall direction and goals of structural elucidation work. Is it worthwhile to study whole coal samples, or should we separate out the various, more or less well-defined...
The goal of the symposium, "Particulate Carbon: Formation During Combustion", held at the General Motors Research Laboratories on October 15 and 16, 1980, was to discuss fundamental aspects of soot formation and oxidation in combustion systems and to stimulate new research by extensive interactions among the participants. This book contains lhe papers and discussions of that symposium, the 26th in an annual series covering many different disciplines which are timely and of interest to both General Motors and the technical community at large. The subject of this symposium has considerable relevance for man in his effort to control and preserve his environment. Emission of particulate carbon into the atmos phere from combustion sources is of concern to scientists and laymen alike. The hope of reducing this emission clearly requires an understanding of its formation during the combustion process, itself an area of considerable long-term research interest. It is our hope that this symposium has served to summarize what is known so that what remains to be learned can be pursued with greater vigor.
