| 제목 | Sulfur and water tolerances of SCR catalyst from marine engine exhaust gas |
| 초록 | In this study, the catalytic performance from exhaust gas emissions containing SO2 and H2O from marine diesel engines using ceramic and metal SCR catalysts was investigated under various reaction temperature (200-400 ℃) and linear velocity (1.5-3.0 m/sec). The sulfur and water tolerances of the catalysts could occur the deactivation of SCR catalyst. The NOx conversions was decreased after both SO2 (70 ppm) and H2O (11%) were fed into the reaction system, and then its activity could be rapidly recovered to 90% after the supply of SO2 and H2O was cut off.
