The objective of this study is to investigate the physicochemical properties of the catalysts and the feasibility of remanufacturing them after removing ash in CDPF using a cleaning agent KOH. Compared with the carbon oxidation ability of fresh CDPF, that of de-ashed CDPF had an insignificant difference due to the low activation energy of CO and $CO_2$. As ash deposited in CDPF was de-ashed with KOH, it had a practical feasibility on remanufacturing point of view, but washcoat was melted about 26%. Further studies were required for the prevention of washcoat loss.
