Fuel, 67(2), 170-172.0016-2361https://dx.doi.org/10.1016/0016-2361(88)90258-Xhttps://hdl.handle.net/20.500.12395/16065The desulphurization of four samples of Central Anatolian lignites by treatment with aqueous NaOH was examined. NaOH concentration and temperature were the significant parameters but the extraction time had only a slight effect. Organic sulphur was not removed from three of the samples but in the other lignite 12.5 wt % of the organic sulphur was removed by treatment at 70°C for 8 h with 20 wt/v % NaOH solution. Total sulphur contents were considerably reduced by aqueous NaOH treatment but one high-sulphur lignite was found to be more resistant to sulphur removal than the others. This lignite was treated with molten caustic at 300°C and 450°C with the result that the total sulphur and ash contents were reduced by 47- 83 wt % and 77-91 wt % respectively.en10.1016/0016-2361(88)90258-Xinfo:eu-repo/semantics/openAccesslignitedesulphurizationalkaliArticle672170172Q1WOS:A1988L878800003N/A
