Development Regenerable MgO Based Sorbents Promoted with Cerium and Iron Oxide for SOx Removal |
| 초록 |
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. In this study, the MgO-based sorbents promoted with Ce and Fe were tested for the removal of SOx and their abilities of SOx absorption as well as regeneration were investigated in a Fixed-bed under RFCC conditions (sulfation in the presence of low concentration of SOx at 700oC, regeneration in the presence of H2 at 530oC). Ce played an important role in the oxidation of SO2 into SO3. The other pomoter Fe improved the regeneration property of the sorbent. The sorbent prepared by impregnation of Ce to the MgCO3 and then it was promoted with Fe by gel-mixing method. Calcination at 750°C condition transformed MgCO3 into MgO phase. It was found that surface area and sulfur removal capacity larger than those of the sorbent promoted for commercially available MgO. It showed the high sulfur removing capacity(SO2 uptake efficiency :97%) and excellent regeneration property. Characterization of sorbnets promoted with Ce and Fe were discussed by the results of BET, XRD, FT-IR. |
