Available in PDF, EPUB and Kindle. Book excerpt: 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, maceral and mineral constituents before attempting to describe the structural and compositional features of coal at the molecular Ievel? Second, should there be more emphasis on key structural features and average statistical parameters, or is it necessary to identify individual chemical structures in considerable detail? From the developments of the past decade it is clear that advanced spectroscopic techniques are playing an increasingly important role in resolving difficult questions with regard to the chemical structure and composition of coal. Moreover, it has become equally clear that no single spectroscopic approach can provide all the answers but multiple techniques need to be used in a highly integrated and synergistic manner.

This book was released on 1989 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project consisted of three sections. In the first part, the physical cleaning of Ohio coal by selective flocculation of ultrafine slurry was considered. In the second part, the mild oxidation process for removal of pyritic and organic sulfur.was investigated. Finally, in-the third part, the combined effects of these processes were studied. The physical cleaning and desulfurization of Ohio coal was achieved using selective flocculation of ultrafine coal slurry in conjunction with froth flotation as flocs separation method. The finely disseminated pyrite particles in Ohio coals, in particular Pittsburgh No. 8 seam, make it necessary to use ultrafine ( -500 mesh) grinding to liberate the pyrite particles. Experiments were performed to identify the ''optimum'' operating conditions for selective flocculation process. The results indicated that the use of a totally hydrophobic flocculant (FR-7A) yielded the lowest levels of mineral matters and total sulfur contents. The use of a selective dispersant (PAAX) increased the rejection of pyritic sulfur further. In addition, different methods of floc separation techniques were tested. It was found that froth flotation system was the most efficient method for separation of small coal flocs.

Download or read book Processing and Utilization of High Sulfur Coals V written by B.K. Parekh and published by Elsevier. This book was released on 2013-10-22 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: Utilization of high sulfur coals is becoming increasingly difficult in view of tighter environmental regulations being imposed around the world. To meet the challenge of utilizing high sulfur coals without damaging the environment, many scientists and engineers around the world are engaged in developing novel technologies. In the U.S.A. alone, the federal government has spent about five billion dollars to achieve that goal. This conference, like its predecessors, emphasizes desulfurization with papers on physical and chemical cleaning as well as post-treatment and fluid-bed combustion technologies. Of the 45 papers submitted, 15 papers deal with physical cleaning and 7 deal with chemical cleaning of coal, suggesting that a major emphasis is still be placed on pre-cleaning of coal. The post-treatment technologies, being developed with the support of U.S. federal and state government agencies, emphasize removal of both SOx and NOx gases. The book will be of particular interest and benefit to researchers, graduate students and other people involved in coal processing, characterization and utilization; public policy making and administration related to energy conservation, economic development, and environmental protection; and investors in industry and new technology.

Download or read book Inorganic Geochemistry of Coal written by Shifeng Dai and published by Elsevier. This book was released on 2023-06-22 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
