Economic and environmental requirements for advanced power generating systems demand the removal of corrosive and other sulfurous compounds from hot coal gas. After a brief account of the world energy resources and an overview of clean coal technologies, a review of regenerable metal oxide sorbents for cleaning the hot gas is provided. Zinc oxide, copper oxide, calcium oxide, manganese oxide based as well as supported and mixed metal oxide sorbents are treated. Performance analysis of these sorbents, effects of various parameters on the desulfurization efficiency, kinetics of sulfidation and regeneration reactions, sulfiding and regeneration mechanisms are discussed. Two chapters present recent results in the direct production of elemental sulfur from regeneration or SO2-rich gases.

Skyrocketing energy costs have spurred renewed interest in coal gasification. Currently available information on this subject needs to be updated, however, and focused on specific coals and end products. For example, carbon capture and sequestration, previously given little attention, now has a prominent role in coal conversion processes.This book approaches coal gasification and related technologies from a process engineering point of view, with topics chosen to aid the process engineer who is interested in a complete, coal-to-products system. It provides a perspective for engineers and scientists who analyze and improve components of coal conversion processes.The first topic describes the nature and availability of coal. Next, the fundamentals of gasification are described, followed by a description of gasification technologies and gas cleaning processes. The conversion of syngas to electricity, fuels and chemicals is then discussed. Finally, process economics are covered. Emphasis is given to the selection of gasification technology based on the type of coal fed to the gasifier and desired end product: E.g., lower temperature gasifiers produce substantial quantities of methane, which is undesirable in an ammonia synthesis feed. This book also reviews gasification kinetics which is informed by recent papers and process design studies by the US Department of Energy and other groups, and also largely ignored by other gasification books.• Approaches coal gasification and related technologies from a process engineering point of view, providing a perspective for engineers and scientists who analyze and improve components of coal conversion processes • Describes the fundamentals of gasification, gasification technologies, and gas cleaning processes • Emphasizes the importance of the coal types fed to the gasifier and desired end products • Covers gasification kinetics, which was largely ignored by other gasification books - Provides a perspective for engineers and scientists who analyze and improve components of the coal conversion processes - Describes the fundamentals of gasification, gasification technologies, and gas cleaning processes - Covers gasification kinetics, which was largely ignored by other gasification books

The text is complemented with practical examples and industrial applications ranging from clean power generation to complex combined heat and power systems and high purity hydrogen for use in fuel cells. Syngas from Waste contains high-quality contributions from leading experts in the field. It is intended for academics at MSc or PhD level, researchers and industry practitioners in syngas production and applications, who are involved in the design, retrofit design and evaluation activities of alternative scenarios. It contains valuable teaching material for lecturers and provides industry professionals with the know-how to evaluate and improve existing installations or even to design a new one.

Energy 2000, proceedings from the 8th in an international series of global energy forums, is now available in book format. These papers provide a broad-based perspective on not only technical energy developments, but a detailed examination into other aspects such as economic and policy assessments, global energy issues, energy efficiency and conservation, as well as architecture and international law. Also presented are individual and collected views on renewables, oil and gas, coal and nuclear. ENERGEX '2000, the 8th in an international series of global energy forums, was held in Las Vegas, July 23-28, 2000. The first in the series was held in Regina, Saskatchewan, Canada in cooperation, coordination and communication with technical societies, federal and provincial governments and industry. The majority of papers presented at the 8th global energy forum are contained in these proceedings and represent over 200 papers from 45 countries out of a total of over 400 accepted abstracts. These papers will provide the reader with a broad based perspective on not only technical energy developments but, as consistent with the International Energy Foundation's objectives, a detailed examination into other aspects such as economic and policy assessments, global energy issues such as global climatic change, energy efficiency and conservation, architecture and international law. ENERGEX '2000 also provided the opportunity for researchers internationally to present their individual and collected views related to the diverse sources of energy available to mankind. These sources include renewables, oil and gas, coal, and nuclear. From ENERGEX 2000 has resulted this new book! Since the inception of the ENERGEX series in 1982, an open door policy has been established so that any researcher from either the developed or the emerging nations will have an equal opportunity to present their individual or collected technical, economic or human dimensional assessments and analyses on an equal footing. Through this participation, researchers worldwide are provided with a wider range of opportunity to expand our horizons with respect to the continued use of fossil energies and nuclear energy combined with energy conservation and efficiency. This opens the door of opportunity in the 21st century with respect to the rapid developments and utilization of renewable energies and fuel cells. Integrated within this global energy forum were inputs from academia, industry and government on specific issues related to carbon sequestration, fuel cells, fossil fuels, hydrogen and the role of the present day energy standards of oil and gas, coal and nuclear energies In expanding the global energy picture, the Foundation developed the conference with the theme "Energy-International Cooperation, Coordination and Communication: The Beginning of a New Millennium." Consistent with this theme we are pleased that ENERGEX '2000 developed the program in concert with the Nevada Test Site Development Corporation (NTS).
