ABSTRACT OF THE DISCLOSURE Hot reducing gas is desulfurized by contacting the gas with a desulfurizing agent comprising a bed of sintered, porour pellets, comprising the reaction product of manganese oxide and aluminum oxide, then regenerating the spent desulfurizing agent by contacting the bed with a gaseous oxidizing atmosphere and then reusing the regenerated desulfurizing agent under the above men- tioned conditions for desulfurizing hot reducing gas. The tempera- ture of the bed of pellets is between about 500° C and about 1300° C during both the desulfurization and the regeneration steps. The invention relates to the pellets and to the processes of making and using these pellets.
