Extraction, separation, and analysis of high sulfur coal. Technical progress report No. 16, July 15, 1991--October 15, 1991

Two processes were studied in the period. The first was a study of oxidative desulfurization processes. Earlier research indicated that the use of copper-promoted oxidation of the organic and inorganic sulfur species in coal showed considerable promise. Initial studies utilizing CuCl{sub 2} demonstrated that the desulfurization yields were much lower than previously quoted. However, the experiments suggested that the reactant pathway showed promise and further investigations were conducted varying the solvent and replacing the Cl{sup {minus}} anion with the OH{sup {minus}} species. Ultimate analyses of these reactions are reported in addition to the experimental conditions used. Reactions using Cu(OH){sub 2}, CuCl{sub 2}, and copper cyclohexane butyrate are investigated. The second process discussed was desulfurization using selective solvation. Supercritical ethanol was used to investigate the extent of organic sulfur removal from coal. (VC)
