Some reagents were added to two kinds of coals, "Miike" and "Matsushima" in order to remove the sulfur during carbonization.<BR>As a sources of active hydrogen, tetraline, isopropyl alcohol and cyclohexane were used.<BR>At the temperature of 500-600°C, tetraline was more effective than hydrogen, to remove the sulfur from coal, but it was not so effective at the temperature higher than 700deg;C.<BR>After converting the organic sullfur to inorganic one, they were washed with water, aqueous acids or alkalines.<BR>Some of Fe-compounds, for example Fe (OH) 3, FeCl2, FeCl3, K4Fe (CN) 6 etc., were also used in Matsushima coal and the mixtures were carbonized at 750deg;C, but it is not so practical.
