摘要：

A 1% Pt on CeO2-promoted PrCrO3 perovskite catalyst has been synthesized over a wall-flow monolith by the in situ solution combustion synthesis (SCS) method. The role of the catalyst, highly active towards diesel particulate combustion, has been studied during the regeneration phase as a function of the inlet trap temperature at which the regeneration is induced. The final aim of this study is to improve the knowledge on the catalytic regeneration process, with reference to the main operating parameters, in order to optimize the fuel penalties during the regeneration and to minimize the CO2 emissions added by the post-injection and combustion of fuel.
