The influence of exhaust gas compositions in MnO2 dry DeSO x filter for diesel emission control
Sulfur dioxide purification has adverse effects on the environment and the human body. In this study, the dry desulfurization process from exhaust gas exhaust by dry DeSO x filter is investigated for constructing a sulfur-based capture-and-reuse system. The activated MnO2 having a high-specific surf...

| Zusammenfassung: | Sulfur dioxide purification has adverse effects on the environment and the human body. In this study, the dry desulfurization process from exhaust gas exhaust by dry DeSO x filter is investigated for constructing a sulfur-based capture-and-reuse system. The activated MnO2 having a high-specific surface area (HSSA MnO2) is utilized as an absorbent to indicate high SO2 capture performance in the low-temperature region. To improve the capture performance, (SO2 concentration, space velocity, and gas composite) is analysed on SO2 capture performance of dry DeSO x filter. Results showed that SO2 capture performance in high SO2 concentration was constant regardless of space velocity. However, in low SO2 concentration, the SO2 capture performance decreased with increasing space velocity. Moreover, the presence of H2O in the flow gas exhibited a beneficial effect on SO2 capture performance |
