  • Desulfurizing pellet of manganese oxide and aluminum oxide and process for producing said pellet
    Patent number: 4230603
    Abstract: Hot reducing gas is desulfurized by contacting the gas with a desulfurizing agent comprising a bed of sintered, porous 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 mentioned conditions for desulfurizing hot reducing gas. The temperature of the bed of pellets is between about 500.degree. C. and about 1300.degree. C. during both the desurfurization and the regeneration steps. The invention relates to the pellets and to the processes of making and using these pellets.
