Title: Analyzing organic sulfur in coal/char: Integrated mild degradation/XANES methods. [Quarterly] technical report, September 1--November 30, 1993

Abstract

To address the acid rain problem effort has been expended on finding methods for the removal of sulfur from coal. Despite these efforts organic sulfur has proven very difficult to remove. Perhaps the single most important reason for this is the fact that the organic sulfur in coal remains very poorly characterized. Thus, objective of this study is to combine advanced nondestructive and advanced destructive methods of sulfur analysis for characterization of the organic sulfur in Illinois Basin coals and mild gasification chars derived from them. Thus, the study combines selective oxidation strategies, analytical pyrolysis, and sulfur X-ray Absorption Near Edge Structure Spectroscopy (XANES) analysis. In, addition identical samples are to be provided for W-Band EPR spectroscopy. During the previous quarter ten coal derived samples have been prepared with the sulfur content varing from 0.77 to 4.4%. Each sample has been submitted for XANES analysis, W-Band EPR analysis, and analytical pyrolysis. A mild gasification reactor has been designed and is undergoing final assembly.
