| 摘要:为解决柴油机在燃用高硫燃料时出现的柴油机颗粒过滤器（diesel particulate filter ，DPF）失活现象，对表面涂覆抗硫材料的SiC/Pt催化剂的催化性能展开测试。结果显示：在小型柴油机试验中，贵金属Pt负载的DPF催化剂的平衡温度可下降至300 ℃，同时涂覆抗硫材料可提升其积炭-再生性能，累计积炭量和单次积炭量均稳定降低。同时DPF装置也可去除气态污染物，NO、CO的转化效率在360 ℃时分别为10.53%和57.19%。 |

| Abstract:In order to address the inactivation phenomenon of diesel particulate filter（DPF）when using high sulfur fuel in diesel engines，the catalytic performance of SiC/Pt catalysts coated with sulfur resistant materials was tested.The results show that in small-scale diesel engine tests，the balance point temperature of noble metal Pt loaded DPF catalyst can be reduced to 300 ℃，and coating with sulfur resistant materials can improve its carbon-regeneration deposition performance，with a stable decrease in both cumulative and single carbon deposition.The DPF device can also remove gaseous pollutants，and the conversion efficiency of NO and CO is 10.53% and 57.19% respectively at 360 ℃. |
