|Title:||Desulphurization study of Assam coking coal by sodium hydroxide leaching|
Singh, A K

|Abstract:||Sulphur removal from Assam coking coal and its coke (made at 1300o C) by caustic leaching at four different temperatures of 50, 85, 105 and 120o C by varying soak periods from 30 to 180 min has been determined. Carbonization of Assam coking coal at 1300o C considerable recued its sulphur content from 7.9 to 3.85%. The total sulphur removed increase with increasing leaching temperature and time. The first 30 min of leaching has been found to be the optimum leaching time for all the temperature. Coke offered more resistance to NaOH leaching for sulfur removal compared to coal.|
