Development regenerable MgO based sorbent promoted with Cobalt and Iron oxide for SOx removal |
| 초록 |
Sulfur oxides (SOx) can be formed by oxidation of sulfur in fossil fuel and emitted from the industrial processes such as a catalyst regeneration unit of RFCC and FCC. In this study, the MgO-based sorbents promoted with Co and Fe were tested for the removal of SOx and their abilities of SO2 absorption as well as regeneration were investigated in a Fixed-bed under RFCC and FCC conditions (sulfation of MgO to MgSO4 in the presence of low concentration of SOx at 700oC, regeneration of MgSO4 to MgO and H2S in the presence of H2 at 530oC). The promoter, Cobalt played an important role in oxidation SO2 into SO3 which could be easily absorbed to the MgO and Iron improved the regeneration property of the sorbent. It was also found that the sulfur removing capacity and regeneration property of the MgO based sorbents promoted simultaneously with Co and Fe depended on the preparation method(coprecipitaion, physical mixing and impregnation method). The sorbent prepared by impregnation of Fe to the Co-MgO prepared by coprecipitiaon of Co and MgO showed the excellent sulfur removing capacity and regeneration property. Characterization of sorbnets promoted with Co and Fe were discussed by the results of FT-IR, XRF, BET. |
