Coal Desulfurization Chemical and Physical Methods ACS Symposium Series No. 64 Thomas D. Wheelock, Editor Iowa State University Based on a symposium sponsored by the Division of fuel Chemistry of the American Chemical Society. The 23 chapters in this volume cover the current research on industrial rocesses and methods for removing sul/h from coal. Both chemical and physical extraction methods that are used currently or that are being adopted currently by industry are reviewed. Related work on characterizing and analyzing the various forms of sulfur in coal is included. This work is significant because it can lead to the development of industrial technology that will enable medium- and high-sulfur coals to be utilized in an environmentally acceptable manner.
