The application of Diesel Particulate Filter (DPF) as after-treatment system has been studied to reduce particle mater(PM) in exhaust gas form vehicle, but there is one challenge which is a regeneration method in the low temperature region. In this study, reforming reaction of diesel fuel was applied as regeneration method. Reforming reaction of diesel fuel to reformate (H₂ and CO) was conducted on PUCe/Al₂O₃ that was made through impregnation method. Reformate was mixed with exhaust gas and gas mixture was injected to DOC. Possibility to apply reforming system was evaluated with the temperature of the exhaust gas on the rear of DOC. In condition that the temperature of exhaust gas was 150℃, the temperature of exhaust gas on the rear of DOC was easily heated to more than 450℃ by reformate of diesel fuel.
