Characterization of Residues from Selected Coal Conversion Processes.
MISSING :13 pages
As part of the Bureau of Mines subactivity in secondary resource recovery and to expand the nation's mineral base, the Tuscaloosa Research Center made characterization and preliminary beneficiation studies of the waste residues from various coal-conversion processes: from pilot plant tests of the synthane process for coal gasification, the synthoil process for coal liquefaction, and the solvent-refined coal (src) process for sulfur removal from coal. Those coal conversion processes selected for this study were based on the availability of pilot plant samples. Physical, chemical, and mineralogical examinations of the wastes made to determine the mineral content prior to physical beneficiation tests indicated that in addition to significant quantities of carbon, some trace elements offer potential for concentration.
