Abstract

Effect of alkali metal cation as an additive in catalytic combustion of Diesel particulate matter (PM)was investigated using TiO₂-supported copper catalysts (M, Cu/TiO₂, M: alkali metal ion) derived from copper ( II ) chloride (CuCl₂, 2H₂O) by the addition of Na+, K+, Rb+ and Cs+ ions, respectively. M, Cu/TiO₂ catalysts except for Na, Cu/TiO₂ showed good catalytic performance of the PM combustion be low 620 K, especially in recycle use. This is attributed to that the presence of compounds consists of M-CuCl promoted the intimate contact between MC1 and Cu species after the decomposition of M-Cu-Cl. Since K, Cu/TiO₂ among M, Cu/TiO₂ catalysts was superior in combustion temperature, potassium is presumed to act favorably for the oxidation of PM.
