Abstract

The lignite in YAYU area,Ethiopia,is studied.The sulfur contents and titration curves of raw coal,desulfate coal,deinorganic sulfur coal samples are analyzed.The titration curves show that the range of complete separation of sulfate sulfur is the longest.The organic sulfur separates first and the separating rate of sulfide sulfur decreases rapidly after its reaching to peak value.
