The simultaneous removal properties of H2S and NH3 on the Al-based catal-sorbents promoted with Ni and Mo in the hot coal gases |
| 초록 |
To use simultaneous removal of H2S and NH3 technology in IGCC process, it is necessary to remove hydrogen sulfide (H2S) by absorption and ammonia (NH3) by decomposition reaction from the hot coal-gases. In this study, the Al-based catal-sorbents promoted with Ni and Mo (MNAp20 and MNAI20) were prepared by physical mixing and impregnation method. The α-MNAI20 catal-sorbents were prepared by the impregnation of α-Al2O3 (Aldrich) with Ni and Mo. Their simultaneous removal properties were tested in fixed-bed reactor during multiple removal reaction and regeneration cycles at high temperature conditions (removal reaction at 650◦C and regeneration at 700◦C). The H2S absorption and NH3 decomposition breakthrough point time of MNAI20 catal-sorbent were 165 min and 155 min, respectively, and the simultaneous removal efficiency was about 94%, while those of the other catal-sorbents were below 55%. The simultaneous removal efficiency of MNAI20 catal-sorbent was excellent, which could be explained to the crystal structure effect and discussed by XRD, XPS and BET. |
