Combined chemical and microbiological removal of organic sulfur from coal
- Institute of Gas Technology, Chicago, IL (USA)
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. During this quarter, samples of IBE-107, ground to {minus}200 mesh, were oxidized with hydrogen peroxide, potassium permanganate, and sodium periodate for three hours and treated microbiologically with the bacterium, IGTS8. A number of blanks were also prepared. Of the forty-one samples in this initial study, 27 are ready for analysis and 14 are presently being treated microbiologically. 1 tab.
