Abstract: SULFUR EXTRACTION FROM COAL BY LEACHING WITH BR2 CONTAINING AQUEOUS HBR HAS BEEN INVESTIGATED FROM AMBIENT TEMPERATURE UP TO 120 DEGREES C. THE OXYDESULFURIZATION WITH BR2 REVEALED TO BE SELECTIVE FOR THE REMOVAL OF THE HIGH LEVELS OF SULFATE AND PYRITIC SULFUR WITHIN A FEW MINUTES OF LEACHING WHILE NO SIGNIFICANT ATTAK OF THE ORGANIC SULFUR COULD BE OBSERVED. AFTER LEACHING A SIGNIFICANT REDUCTION OF THE ASG CONTENT AND THE UP-TAKE OF SUBSTANTIAL QUANTITIES OF BR2 WERE FOUND. THE HALOGEN CAN BE REMOVED AS HBR BY THERMAL TREATMENT. FOR REDUCTIONS TO BELOW 0.1% LEVELS ONE TO TWO HOURS AT AROUND 500 DEGREES C. WERE NEEDED. (KEYWORDS: COAL, LEACHING, BROMINE, HYDROBROMIC ACID, DEBROMINATION)
