| Abstract(J) | 厳しい排ガス規制に対応できる三元触媒の開発のため，触媒反応メカニズムに基づいた汎用的で高精度な触媒反応モデルの構築が求められている．しかし，排ガス中に含まれる水が三元触媒上での浄化反応に及ぼす影響が明確でない．そこで本研究では，現在多く用いられているパラジウム系三元触媒を用いて，水が触媒上での排ガス浄化反応に及ぼす影響を明らかにするとともに，その結果に基づいた触媒反応モデルの構築を行った． Translation |
| Abstract(E) | To develop a high-performance three-way catalyst, it is necessary to construct an accurate catalytic reaction model. Previously, we have developed the three-way catalyst model under dry simulated exhaust gas conditions. Water, which is contained in the real exhaust gas, however, complicate the phenomenon encountered in the three-way catalyst. Thus, in this study, the effect of water on the catalytic reaction on a palladium-based three-way catalyst was investigated. Moreover, a catalytic reaction model was developed based on the experimental results. As a results, it is found that the constructed model well predicted the light-off behavior of the palladium-based three-way catalyst. |
