The impetus for this book is twofold. First, in response to the well documented oil shocks of the 1970s there arose a resurgence of research activity in the synthetic fuels area. This book attempts to capture some of the leading edge advances which have been made over the past decade in the area of the chemistry of coal conversion. The second driving force behind this book is to jog people's memories about the fundamental truths of the energy industry, i. e. , there IS a finite amount of liquid hydrocarbons on and under the earth's surface, most of the easy to find, produce, and use liquid hydrocarbons have been exploited, and the real need continues to be for liquid hydrocarbons for use as trans portation fuels. The uncertainty is not if synthetic liquids will be needed, but rat her when they will be needed. The inability to answer that question accurately caused many of the financial and research disruptions following the double shocks of the 1970s. Since future projections can only be based upon the historical record, they cannot anticipate major disruptions such as, e. g. , discovery of huge easily producible oils fields, or, on the other side, global or regional economic disruptions such as warfare. With this level of uncertainty, then, the second impetus is to point out how much research remains to be done at a time when fiscal support for fossil fuels research in the Uni ted States is rapidly spiraling downward.

Process Chemistry of Coal Utilization: Reaction Mechanisms for Coal Decomposition and Volatiles Conversion relates major advances in coal science on how to interpret performance data from lab, pilot and commercial scales. The book presents a very broad range of quantitative methods, from statistical regressions, to rudimentary models, CFD and comprehensive reaction mechanisms. Combining the latest research in the field, including an abundance of lab datasets, the book illustrates how a particular operating condition affects a specific coal-based reaction system. Managers who use these tactics will be able to tailor their testing and simulation work to effectively characterize and solve their problems. - Compiles fully validated reaction mechanisms that accurately depict the coal quality impacts in all major coal utilization technologies - Includes an abundance of lab datasets that clearly illustrate how operating conditions affect coal-based reaction systems

Filling the need for new and improved energy sources is an area where societal effects of science and technology will surely increase. The editors and authors have attempted in this volume to present the most current work on the science and technology of coal and coal utilization. Serious disagreement exists on several key issues such as carbon dioxide release and acid rain. At the same time, however, coal is the world's most abundant fossil fuel and will have to be used to supply the world's energy needs for the next several decades. The 1979 National Research Council Report, "En ergy in Transition: 1985-2010," has estimated that the United States alone may go from a 1979 coal consumption of 14 QUADS per annum (approximately 750 million tons per year) to approximately 40-50 QUADS per annum (approximately 2 billion tons per year) by the year 2010. If this scale of coal utilization is to become a reality, a significant level of research and development will be necessary to establish advanced process technologies and to improve related areas such as materials and instrumentation. The editors hope that this volume will allow a technically educated person to become aware of the several aspects of coal utilization, from characterization of coal itself to the processes of coal utilization.

This report, Coal Data: A Reference, summarizes basic information on the mining and use of coal, an important source of energy in the US. This report is written for a general audience. The goal is to cover basic material and strike a reasonable compromise between overly generalized statements and detailed analyses. The section S̀̀upplemental Figures and Tables̀̀ contains statistics, graphs, maps, and other illustrations that show trends, patterns, geographic locations, and similar coal-related information. The section C̀̀oal Terminology and Related Information ̀̀provides additional information about terms mentioned in the text and introduces some new terms. The last edition of Coal Data: A Reference was published in 1991. The present edition contains updated data as well as expanded reviews and additional information. Added to the text are discussions of coal quality, coal prices, unions, and strikes. The appendix has been expanded to provide statistics on a variety of additional topics, such as: trends in coal production and royalties from Federal and Indian coal leases, hours worked and earnings for coal mine employment, railroad coal shipments and revenues, waterborne coal traffic, coal export loading terminals, utility coal combustion byproducts, and trace elements in coal. The information in this report has been gleaned mainly from the sources in the bibliography. The reader interested in going beyond the scope of this report should consult these sources. The statistics are largely from reports published by the Energy Information Administration.
