| Abstract: | At 625°C the percentage of sulfur in the non-volatile portion of the Bapung coal beds ranges from 1.08 to 3.10 wt.%, with the pyritic sulfur ranging from 0.02 to 0.32 wt.%, the sulfate sulfur ranges from 0.02 to 0.30 wt.%, and the organic sulfur from 0.88 to 2.49 wt.%. The total sulfur in the Bapung coal ranges from 2.50 to 12.44%. Organic sulfur appears to be more abundant among the different sulfur species. However, the pyritic sulfur increases quickly as the total sulfur content increases at 925°C, the percentage of sulfur in non-volatile portion ranges from 1.27 to 2.54 wt.%, with pyritic sulfur ranging from 0.02 to 0.56 wt.%, sulfate sulfur ranges from 0.04 to 0.16 wt.%, and the organic sulfur from 1.15 to 2.03 wt.%. |
