Development of AgPd Catalyst for PM Combustion

PM 燃焼用AgPd 触媒の開発

The authors have developed new AgPd catalyst for Catalyzed Soot Filter (CSF) which has low pressure-drop and also high combustion performance of Particulate Matter (PM). By alloying Ag and Pd enabled to improve PM combustion performance and thermal stability, and also the layer coating(coating on the wall of Diesel particulate filter(DPF)) enabled the catalyst to contact PM more efficiently compared to the conventional Pt-CSF with the catalyst coated in the wall of DPF, which resulted in hi-efficiently regeneration of PM.PM再生時のCO2低減，触媒劣化の抑制を狙い，高効率再生可能な新しいAg系CSFを開発した．AgPd合金化によりPM燃焼性能及び耐熱性向上し，さらにDPF壁の表層に担持することにより，従来の壁内担持されたPt系CSFに比べるとPMとの高接触化により高効率再生を実現することができた．
