| 摘要: |
| 为系统研究贵金属催化同时去除碳颗粒和NOx的活性及抗硫抗水性能,采用等体积浸渍法制备了一系列贵金属催化剂(Ru／ZrO2、Ag／ZrO2、Rh／ZrO2、Pd／ZrO2、 Pt／ZrO2 、Ir／ZrO2、 Au／ZrO2),研究了富氧条件下其催化去除碳颗粒和NOx的活性,并考察了SO2和H2O对其催化活性的影响．结果表明:在富氧条件下,贵金属的负载提高了碳颗粒和NOx同时去除的活性,其中Ru／ZrO2、Ag／ZrO2和Pd／ZrO2的催化活性较佳;SO2和H2O对Ir／ZrO2催化同时去除碳颗粒和NOx、Pt／ZrO2催化去除碳颗粒、Ru／ZrO2催化去除NOx有促进作用,但对其他贵金属有抑制作用． |

| Abstract: |
| In order to systematically evaluate the activities of the noble metal catalysts for simultaneous removal of soot and NOx and the corresponding effect of sulfur and water, a series of noble metal catalysts (Ru／ZrO2, Ag／ZrO2, Rh／ZrO2, Pd／ZrO2, Pt／ZrO2, Ir／ZrO2, Au／ZrO2) were prepared by iso-volumetric impregnation method firstly. Then the activities of the noble metal catalysts for simultaneous removal of soot and NOx were measured under oxygen-rich condition, and the effect of SO2 and H2O on the performances of those catalysts were also studied. Experimental results showed that noble metal can improve the activities of simultaneous removal of soot and NOx significantly. Compared with the other catalysts, Ru／ZrO2, Ag／ZrO2and Pd／ZrO2 have higher catalytic activity. The existence of SO2 and H2O promoted Ir／ZrO2 catalystal removal of soot and NOx simultaneously, promoted Pt／ZrO2 catalyze for soot oxidation, Ru／ZrO2 for NOx reduction and inhibited the catalytic activities of other noble metals. |
