%X In this study, cerarnics honeycomb-supported ABO3 perovskite type oxides were preparedby changing the composition of A and B site cations, and observed their activities for lean CH4 oxidation. In the case of change in A site composition La0.3Sr0.2MnO3 and La0.6Sr0.4MnO3 is the mostactive catalysts for 1 v% CH4 and 2 v% CH4 respectively. But LaMn0.5Co0.5O3 oxide is the best ac-tive catalyst for 1-2v% CH4 among the oxides by changing B site compositions of LaBO3 and su-perior to La0.3Sr0.2MnO3 and La0.6S0.4MnO3catalysts.Adding trace Pd improved the activity and characteristics of space velocity for LaMn0.5CO0.5O3and La0.3Sr0.2MnO3 Although LaMn0.5Co0.5O3 +Pd (0.03 wt%) was less active than the Pd catalyst,the activity was more than Pt catalyst at a conversion level below 90%.
