This book was released on 1991 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study clearly demonstrated the usefulness of liquid- and solid-state 13C- and 1H-NMR for the examination of process-derived materials from direct coal liquefaction. The techniques can provide data not directly obtainable by other methods to examine the saturation of aromatic rings and to determine the modes of hydrogen utilization during coal liquefaction. In addition, these methods can be used to infer the extent of condensation and retrograde reactions occurring in the direct coal liquefaction process. Five NMR techniques were employed. Solid-state 13C-NMR measurements were made using the Cross Polarization Magic Angle Spinning (CP/MAS) and Single Pulse (SP) techniques. Solid-state 1H-NMR measurements were made using the technique of Combined Rotation and Multiple-Pulse spectroscopy (CRAMPS). Conventional liquid-state 12C- and 1H-NMR techniques were employed as appropriate. Interpretation of the NMR data, once obtained, is relatively straightforward. Combined with other information, such as elemental analyses and process conversion data, the NMR data prove to be a powerful tool for the examination of direct coal liquefaction process-derived material. Further development and more wide-spread application of this analytical method as a process development tool is justified on the basis of these results.

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.

This book was released on 2013-11-21 with total page 1630 pages. Available in PDF, EPUB and Kindle. Book excerpt: There have been many developments in the science and technology of thermo chemical biomass conversion since the previous conference on Advances in Thermochemical Biomass Conversion in Interlaken, Switzerland, in 1992. This fourth conference again covers all aspects of thermal biomass conversion systems from fundamental research through applied research and development to demon stration and commercial applications to reflect the progress made in the last four years. All aspects of bioenergy systems are covered from pretreatment through to end-user applications with increased consideration paid to the environmental benefits and problems of implementing bio-energy systems. There was an excellent response with over 200 papers offered and over 180 delegates from 29 countries attending the conference. The programme was divided into five main areas covering pyrolysis, pretreatment, gasification, combustion and system studies and this division is reflected in the structure of these conference proceedings. Each main section was preceded by a state-of-the-art review to provide a focus for the ensuing presentations and an authoritative reference. All the papers included have been subject to a full peer review process. As with any international conference, an important aim was to exchange ideas and discuss problems with fellow researchers, as well as to hear about the latest research and development and applications. A workshop programme was included to encourage this interaction in areas of interest selected by participants. The resul tant workshop reports provide a summary of topical problems and opportunities.
