采用流动法考察蜂窝陶瓷负载Pd催化剂催化氧化C3H8、C3H6和CO的活性和高温热稳定性，探讨了非贵金属氧化物、La改性以及水蒸气预处理等因素对Pd催化剂的氧化性能及高温稳定性的影响，为该催化剂的进一步研究提供基础参数．
The catalytic activity and high temperature thermal stability of C3H8, C3H6 and CO catalyzed by Pd catalyst supported on honeycomb ceramics were investigated by flow method. The effects of non-noble metal oxides, La modification and water vapor pretreatment on the oxidation performance and high temperature stability of Pd catalysts were discussed. The impact of the nature of the catalyst for further research to provide the basic parameters.
