| 摘要 |
Elementary sulfur is obtained from sulfur-containing materials which release sulfur oxides (SOx) in the presence of oxygen by fluidizing such materials in a bed with an oxygen-containing gas (e.g., air), and passing the resulting SOx-containing gases through a bed (preferably fluidized) of carbonaceous or carbon-containing solids (such as coke or coal) at an elevated temperature to reduce SOx to elemental sulfur, the bottom of the bed of carbonaceous or carbon-containing solids being at about the level of the top of the bed of sulfur-containing materials.
