Southeastern Anatolian asphaltites are notoriously high in sulfur and
therefore not suitable for direct use in combustion without extensive
cleaning. In order to remove sulfur from asphaltites collected from Si
rnak and Hazro, the Meyers (Fe3- salts) method was used. The effects o
f ferric concentration, coal particle size, temperature and time on th
e extraction efficiency were investigated and the experimental results
are presented here. Most of the pyritic and sulfate sulfur was elimin
ated from the asphaltite samples. (C) 1997 Elsevier Science B.V.
