Biodesulfurization of coals by use of Thiobacillus ferrooxidans was examined, and the coking property of the biodesulfurized coal was investigated in terms of button index. The % removal of inorganic sulfur was 40-90% when the biodesulfurization was carried out for three high sulfur coals. Also, the biodesulfurization favorably worked for the removal of As and Se from coal. Moreover, a good correlation was observed between the removal of As from coal and that for inorganic sulfur. For the coking property of the biodesulfurized coal, the button index was not varied. The results suggest that the biodesulfurization is a useful process not only for steam coals but also for coking coals.
