Abstract
A description is presented of studies on coal desulfurization and related investigations. The work has emphasized the application of non-isothermal kinetic studies to the theoretical, experimental, and practical problems associated with the removal of sulfur from coal. To increase the efficiency and precision of data acquisition and interpretation, a computerized non-isothermal kinetic laboratory has been designed, built, and put into operation. Detailed non-isothermal kinetic studies of the desulfurization and gasification of five bituminous coals, lignite, anthracite, and pyrite, under reducing and oxidizing atmospheres have been conducted. An attempt has been made to identify the types of sulfur bonding associated with the removal of sulfur. Non-isothermal kinetic measurements7 of the removal of hydrogen sulfide produced in the desulfurization under both reducing and oxidizing condition by calcium oxide and dolomite have been carried out. Reactions of hydrogen sulfide with iron, iron sulfide, and various coal chars have also been investigated.
