Desulfurization behavior was followed in rapid pyrolysis of coals with the use of free-fall reactor under a nitrogen stream at a terminal temperature of 1253 K. The extent of organic sulfur removal from solid phase ranging from 33% to 90% did not correlate well with carbon content and aromatic carbon fraction of parent coals. XANES analysis for density-separated samples indicated that lower density group had higher content of organic sulfur including thermally decomposable sulfide. Thermally stable thiophenic sulfur was observed in the higher density group as a major form of organic sulfur. A good correlation was obtained between the extent of organic sulfur removal and aromatic carbon fraction for the density separated samples.
