Desulfurization of some turkish lignites during oxidation by air

Abstract

Abstract The effect of air treatment on the desulfurization of seven Turkish lignites was investigated and the experimental results are presented. Lignite samples were oxidized at 550 °C for 15 min using particles with diameters in the range 0.1–0.2 mm. The changes in proximate and ultimate analyses, in total sulfur and in forms of sulfur in lignite samples were studied.
