| 초록 |
This study was carried out to investigate the aging and conversion characteristics of oxidation catalysts for a natural gas vehicle with lean-bum system. The conversion of CII₄ was observed over the various composition ratio of PMs(Precious metals) and washcoating methods. On the fresh catalysts, Pd affected on the activity of CH₄ at low temperature more than other PMs in Pd-only and Rh/Pd/Pt catalysts. The activity at low temperature increased as a mount of Pd increases. On the aged catalysts. the CH₄ conversion efficiency of Pd-only catalyst with mono-layer washcoat decreased more than that of the other catalysts of CH₄ conversion. It was observed that the thermal durability of RhlPd/Pt catalysts with double-layer washcoat was better than the single washcoat catalyst. {{br}} |
