内容説明
Utilization of high sulphur coals is becoming increasingly difficult in view of tighter environmental regulations being imposed around the world. To meet the challenge of utilizing high sulphur coals without damaging the environment, countless scientists and engineers around the world are engaged in developing novel technologies. In the USA alone, the federal government has spent about five billion dollars to achieve that goal. This conference, like its predecessors, emphasizes desulphurization 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 seven deal with chemical cleaning of coal, suggesting that a major emphasis should still be placed on pre-cleaning of coal. The post-treatment technologies, being developed with the support of US federal and state government agencies, emphasize removal of both SOx and NOx gases.
The book should 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.
