Combustion of coals to produce electricity has created environmental problems, one of which is sulphur which is converted to SO2 and SO3 gases. In order to produce a "clean coal", the pretreatment processes of sulphur removal from coal have to be effective to remove the inorganic (pyrite) and organic sulphur forms (thiolic, sulphidic and thiophenic). High pressure Temperature-Programmed Reduction (TPR) has been used for specifying the distribution of organic sulphur forms in both pyrite-free Malaysian (Mukah Balingian) and Indonesian coals (Banjarmasin Hj. Ali-Aliansar and Banjarmasin Coal A). The results obtained thus far, indicate that ca. 95% and 75% of sulphidic functionalities are present in Mukah Balingian (MB) and Banjarmasin Coal A (BMA), respectively, with 70%) thiophenic forms are present in Banjarmasin Hj. Ali- Aliansar (BMHAA).
