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 (free swelling index). The % removal of inorganic sulfur was 40-90% when the biodesulfurization was carried out for four high sulfur coals. Also, biodesulfurization favorably worked for the removal of As and Se from coal. The chemical structures and coking property was not changed after biodesulfurization. These results suggest that the possibility of clean coke preparation from biodesulfurized coals.
