The objective of this work is to investigate techniques for chemically converting the sulfur containing organic compounds in coal to compounds that can be treated microbiologically to remove the organically bound sulfur. The goal is to achieve an economically feasible mild chemical oxidation of the organic sulfur in a representative Illinois Basin coal by converting the sulfur to sulfoxides and sulfones; the carbon sulfur bond in the sulfoxides and sulfones would then be broken microbiologically and the sulfur removed from the coal as a sulfate. In initial studies, it was found that the combination treatments of sodium periodate/micorbial and hydrogen peroxide/microbial resulted in reductions of total sulfur or organic sulfur of 12--13%. 1 fig., 3 tabs.
