Desulfurization of Low Sulfur Coal by it Acidianus brierleyi: Effects of Microbial Treatment on the Properties of Coal

Olsson, G; Larsson, L; Holst, Olle LU and Karlsson, Hans LU (1993) In Fuel Processing Technology 33(2). p.83-93
Abstract
The effect of microbial desulfurization of two different low-sulfur coals by the thermophilic archaebacteria Acidianus brierleyi was studied with respect to the following properties of the coal: porosity, surface area, pore diameter, particle size, heating value, proximate and ultimate analyses as well as ash composition. About 35-40 percent of the sulfur was oxidized microbially. The microbial treatment only had a slight or negligible effect on most properties. Significant increases were seen with respect to oxygen content and volatile matter for one of the coals. The ash content had a significant increase in phosphorus which originated from the growth medium. Furthermore, jarosite formation was significant, especially for one of the... (More)

Significant increases were seen with respect to oxygen content and volatile matter for one of the coals. The ash content had a significant increase in phosphorus which originated from the growth medium. Furthermore, jarosite formation was significant, especially for one of the coals investigated. For the same coal a large increase in porosity was seen and the surface area decreased significantly at the same time. (Less)
