| Abstract: | Demineralization and desulphurization of high sulphur coal from YMSH and SBSH was investigated using aqueous sodium hydroxide followed by hydrochloric acid treatment Compared to the alkali and acid alone,successive treatments with the alkali and acid resulted in significant removal of mineral matters and sulphur from the coal.Demineralization and desulphurization were found to increase with the increase in alkali concentration.Alkali treatment resulted in formation and precipitation of sodium aluminosilicate,which subsequently undergoes decompositionand solubilizafion in presence of acid It is possible to remove 47.4R.2% of the ash,total inorganic sulphur and around 14%-17% organic sulphur from the coal by treatment with 16% sodium hydroxide solution followed by 10% hydrochloric acid. |
