Book Synopsis Advanced Methodologies in Coal Characterization by : Henri Charcosset
Download or read book Advanced Methodologies in Coal Characterization written by Henri Charcosset and published by Elsevier Publishing Company. This book was released on 1990 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of basic research in coal science in France is treated in this book, followed by a presentation of a minibank of 5 French coals of different rank. The main part of the book deals with a description of improved methods of coal characterization and their applications to the coals of the minibank. The results are divided into three sections: 1) Raw coals, 2) Products of extraction, oxidation and pyrolysis and 3) Macerals. An overall discussion of the whole assembly of new methods and information follows the series of research papers. This volume will be of value to those involved in the field of coal characterization for conversion processes, both in the short term and in the future. Since these methodologies are not restricted to coal characterization but extend to carbonaceous materials in general, e.g. oil shales, petroleum residues and heavy petroleums, this book will be of interest to a wide ranging readership.
Book Synopsis Handbook of Coal Analysis by : James G. Speight
Download or read book Handbook of Coal Analysis written by James G. Speight and published by John Wiley & Sons. This book was released on 2005-05-13 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: All the guidance needed to test coal and analyze the results With the skyrocketing costs of most fuel sources, government, industry, and consumers are taking a greater interest in coal, an abundant and inexpensive alternative, which has been made more environmentally friendly through new technology. Published in response to this renewed interest, Handbook of Coal Analysis provides readers with everything they need to know about testing and analyzing coal. Moreover, it explains the meaning of test results and how these results can predict coal behavior and its corresponding environmental impact during use. The thorough coverage of coal analysis includes: * Detailed presentation of necessary standard tests and procedures * Explanation of coal behavior relative to its usage alongside the corresponding environmental issues * Coverage of nomenclature, terminology, sampling, and accuracy and precision of analysis * Step-by-step test method protocols for proximate analysis, ultimate analysis, mineral matter, physical and electrical properties, thermal properties, mechanical properties, spectroscopic properties, and solvent properties * Emphasis on relevant American Society for Testing and Materials (ASTM) standards and test methods, including corresponding International Organization for Standardization (ISO) and British Standards Institution (BSI) test method numbers To assist readers in understanding the material, a glossary of terms is provided. Each term is defined in straightforward language that enables readers to better grasp complex concepts and theory. References at the end of each chapter lead readers to more in-depth discussions of specialized topics. This is an essential reference for analytical chemists, process chemists, and engineers in the coal industry as well as other professionals and researchers who are looking to coal as a means to decrease dependence on foreign oil sources and devise more efficient, cleaner methods of energy production.

Book excerpt: The paper submitted earlier on the use of (bicyclo[3.2.1]4pyrrolidino-N-methyl-octan-8-one triflate) ([sup 13]CO-123) as a [sup 13]C intensity standard was accepted for publication. Subsequently, [sup 13]CO-321 was used in this manner for quantitative [sup 13]C CP-MAS NMR analysis (including spin counting) of Argonne Premium coals. The cross-polarization time constants, T[sub CH], and the rotating-frame proton spin-lattice relaxation times, T[sub 1p][sup H], were determined for each major peak of each coal via a combination of variable contact-time and variable spin-lock (T[sub 1p][sup H]) experiments. Two or three components of rotating-frame [sup 1]H relaxation decay and two or three components of T[sub CH] behavior were observed for each major [sup 13]C peak of each coal. These data were used to determine the number of carbon atoms detected in each coal; these values are in the range between 77% and 87% of the amount of carbon known to be in each coal from elemental analysis data, except for Pocahontas No. 3, for which only 50% of the carbon was detected. In an attempt to use [sup 1]H CRAMPS to elucidate chemical functionality in coal, pyridine-saturated samples of the Argonne Premium coals were examined in detail in terms of their [sup 1]H CRAMPS NMR spectra. These spectra were deconvoluted to yield relative concentrations for individual peaks.

Book excerpt: The paper submitted earlier on the use of (bicyclo[3.2.1]4pyrrolidino-N-methyl-octan-8-one triflate) (13CO-123) as a 13C intensity standard was accepted for publication. Subsequently, 13CO-321 was used in this manner for quantitative 13C CP-MAS NMR analysis (including spin counting) of Argonne Premium coals. The cross-polarization time constants, T{sub CH}, and the rotating-frame proton spin-lattice relaxation times, T{sub 1p}{sup H}, were determined for each major peak of each coal via a combination of variable contact-time and variable spin-lock (T{sub 1p}{sup H}) experiments. Two or three components of rotating-frame 1H relaxation decay and two or three components of T{sub CH} behavior were observed for each major 13C peak of each coal. These data were used to determine the number of carbon atoms detected in each coal; these values are in the range between 77% and 87% of the amount of carbon known to be in each coal from elemental analysis data, except for Pocahontas No. 3, for which only 50% of the carbon was detected.

This book was released on 1993 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project addressed two main goals and one much smaller one. The main goals were (1) to improve the significance, reliability and information content in high-resolution NMR (nuclear magnetic resonance) characterization of coal samples and (2) to develop chemically informative NMR imaging techniques for coal. The minor goal was to explore advanced features of dynamic nuclear polarization (DNP) as a technique for coal characterization; this included the development of two DNP probes and the examination of DNP characteristics of various carbonaceous samples, including coals. 13C NMR advances for coal depended on large-sample MAS devices, employing either cross-polarization (CP) or direct polarization (DP) approaches. CP and DP spin dynamics and their relationships to quantitation and spin counting were elucidated. 1H NMR studies, based on CRAMPS, dipolar dephasing and saturation with perdeuteropyridine, led to a 1H NMR-based elucidation of chemical functionality in coal. 1H and 13C NMR imaging techniques, based on magic-angle spinning and rotating magnetic field gradients, were developed for introducing chemical shift information (hence, chemical detail) into the spatial imaging of coal. The TREV multiple-pulse sequence was found to be useful in the 1H CRAMPS imaging of samples like coal.

Download or read book Advanced NMR Approaches in the Characterization of Coal. [Quarterly] Report written by and published by . This book was released on 1992 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: A considerable effort in this project during the past few months has been focussed on the development of 1H and 13C NMR imaging techniques to yield spatially-resolved chemical shift (structure) information on coal. In order to yield the chemical shift information, a solid-state NMR imaging technique must include magic-angle spinning, so rotating gradient capabilities are indicated. A 13C MAS imaging probe and a 1H MAS imaging probe and the circuitry necessary for rotating gradients have been designed and constructed. The 1H system has already produced promising preliminary results, which are briefly described in this report.
