Development of AgPd Catalyst for PM Combustion

Abstract

We 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.
