SOx removal performance of MgO based sorbent promoted with Cerium and Iron oxide |
초록 |
MgO-based SO2 sorbent promoted with Ce, Co, Fe and Cu were developed for the use in the regeneration unit of RFCC and FCC. Their abilities of SO2 absorption as well as regeneration were investigated in Fixed-bed under RFCC and FCC conditions(sulfation of MgO to MgSO4 in the atmosphere of SO2 : 700℃, regeneration of MgSO4 to MgO and H2S in the presence of H2 : 530℃). The promoters such as Cerium, Cobalt and Iron played an important role in transforming SO2 into SO3 could can easily absorb to the MgO and their abilities of oxidation increased in the following order: Fe<Co<Ce. The regeneration properties of the MgO based sorbent(hydrogenation of metal sulfate to the metal oxide and H2S) depended on these promoters in regeneration condition. In regeneration performance, regeneration rate of Mg-based sorbent promoted with Fe was faster than those promoted with Co and Ce. So far, MgO sorbent promoted simultaneously with Ce and Fe was prepared and it showed SO2 removal and regeneration abilities in RFCC and FCC unit in that this material could satisfy with requirement of SO2 absorption and regeneration performance. |
