摘要：

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 coals investigated. For the same coal a large increase in porosity was seen and the surface area decreased significantly at the same time.
