| Abstract: |
| Thermal regeneration experiments of an industry waste desulfurizer were carried out under nitrogen atmosphere.Thermal regeneration and saturated desulphurization experiments of the waste desulfurizer were carried out under different temperature at same nitrogen atmosphere. Iodine number and pH value of the regeneration products and saturated desulphurization products were determined to investigate saturated sulfur capacity after regeneration. The sample with best regeneration performance was selected to make hydrogen sulfide breakthrough curve analysis. The results showed that40% saturated sulfur capacity is regenerated after first regeneration under450℃, and43% under500℃. |
