Apr 01, 1972· Abstract. The extent of sulphur removal from seven U.S. coals has been studied by low-temperature oxidation. The total sulphur in these coals varied between 3 and 7% by weight. The pyritic sulphur constituted approximately 50% of the total sulphur. A major part of the study has been carried out at oxidation temperatures of 350, 400 and 450 °C.
