Desulfurization of southeastern Anatolian asphaltites by the Meyers method

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 Sirnak and Hazro, the Meyers (Fe3- salts) method was used. The effects of ferric concentration, coal particle size, temperature and time on the extraction efficiency were investigated and the experimental results are presented here. Most of the pyritic and sulfate sulfur was eliminated from the asphaltite samples. (C) 1997 Elsevier Science B.V.
