THE CURRENT STATE OF THE ART of several aspects of asphaltene is presented in this volume. It documents the proceedings of the Internationl Symposium on Asphaltene Particles in Fossil Fuel Exploration, Recovery, Refining and Production Processes sponsored by the Fine particle Society (FPS). This meeting was held il1 Las vegas, Nevada, July 13 -17, 1992. The symposium upon which this volume is based was organized in four sessions emphasizing various basic and applied aspects of research on asphaltene technology. Major topics discussed involve surface phenomena of asphaltene, processed and unprocessed bitumen, asphaltene effect on natural and accelerated ageing of bitumens, asphaltene conversion, theoretical aspects of asphaltenes and interactions of asphaltene colloids in organic solvents. This edition includes eighteen selected papers presented at the symposium. These papers are divided in four broad categories: (1) Bitumen and Coal-Derived Asphaltenes, (2) Asphalt and Asphaltene conversion, (3) Surface and Colloidal Aspects of Asphaltenes, and (4) Thermodynamic and Molecular Aspects of Asphaltenes.

This volume had its birth from a symposium organized by the Macromolecular Secretariat of the American Chemical Society in Atlanta, GA, 1991. Since Macromolecular SeCretariat has five participating divisions-Polymer Chemistry; Polymer Materials: Science and Engineering Division; Colloid and Surface Chemistry Division; Cellulose, Paper and Textile Division; and Rubber Division-the speakers were invited from these disciplinaries and they are truly interdisciplinary in multidisciplinary areas. A number of papers are from the presentations at this symposium. However, some papers were subsequently invited to be sent in. Therefore, many papers have cited references with dates as late as this current year. This book emphasizes applications, and some of the papers were finished in 1993. Therefore, it is timely for scientists and engineers interested in this area of progress. For scientists and engineers who are not familiar with this field, since the development is still youthful, this volume will cover some new frontiers, such as electronics, medical devices, fossil fuels, asphaltics, geochemistry, and environmental engineering. With that in mind, this book can be very useful as a reference. We do include a number of review papers · in this volume. In summary, this book contains sixteen chapters with twenty-eight authors from various organizations and specialties.

The environment is an invaluable resource, and understanding its chemistry is essential to the continued sustainability of life on earth. Environmental science, which builds on the foundation of chemistry, seeks to remedy the present deterioration and degradation caused by humans, and to create new technology that will prevent further damage.This book deals comprehensively with the five essential global cycles or environspheres — lithosphere (minerals and energy sources), atmosphere (air), hydrosphere (water), pedosphere (soil), and biosphere (life) — and provides a clear overview of the crucial interaction away them. It covers the chemistry of energy resources and aspects of biochemistry, geochemistry, and toxicological chemistry, in addition to the three important areas of air, water, and soil; in the process, it links chemical principles with environmental issues. With the fundamental principles presented clearly and the topics covered in a logical sequence, this book can be used as a textbook of environmental chemistry for the environmental engineering or environmental science major. It can also be used as a reference book for environmental professionals.

Engineering requires applied science, and chemistry is the center of all science. The more chemistry an engineer understands, the more beneficial it is. In the future, global problems and issues will require an in-depth understanding of chemistry to have a global solution.This book aims at bridging the concepts and theory of chemistry with examples from fields of practical application, thus reinforcing the connection between science and engineering. It deals with the basic principles of various branches of chemistry, namely, physical chemistry, inorganic chemistry, organic chemistry, analytical chemistry, surface chemistry, biochemistry, geochemistry, fuel chemistry, polymer chemistry, cement chemistry, materials chemistry, and asphalt chemistry. Written primarily for use as a textbook for a university-level course, the topics covered here provide the fundamental tools necessary for an accomplished engineer.

This book deals with basic principles such as chemical equilibrium and chemical processes, concepts which make up the basic tools necessary to design a more efficient system to solve environmental problems.Useful as a textbook for both graduate and undergraduate, the material also serves as an excellent source for professional research in the field of environmental engineering or environmental science.
