Cleaning of pulverized (-200 mesh) coal is a potentially cost-effective strategy for removing mineral matter and associated minor and trace elements from coal prior to combustion, thereby minimizing the release of pollutants to the atmosphere during combustion. Of special concern are those trace elements designated as potential hazardous air pollutants (HAPs) in the 1990 Amendments to the Clean Air Act. Various physical and chemical cleaning methods have been examined with regard to their efficiency for removal of trace elements from coal. Although the mode of occurrence is recognized to be a key factor in determining the behavior of a given element with respect to a specific cleaning method, no study, as far as we are aware, has attempted to include such information. A Kentucky No. 9 coal was physically and chemically cleaned. The coal was then characterized. Results are described.
