Catalytic Oxidation

Aim of this project is regarding diesel soot emission, its adverse effects on the human health, environment, vegetations, climate, etc. The legislations to limit diesel emissions and ways to minimize soot emission. This project was describes the kinetics of catalytic oxidation of diesel soot with air under isothermal conditions. Kinetics data were collected in a specially designed mini-semi-batch reactor. CuO-CeO2 systems have been proposed as a promising catalyst for low temperature diesel-soot oxidation.CuO-CeO2 catalysts prepared by various methods were examined for air oxidation of the soot in a semi batch tubular flow reactor. It was observed that the activity and stability of the catalysts greatly influenced by the preparation methods. The strong interaction between CuO and CeO2 is closely related to the preparation route that plays a crucial role in the soot oxidation over the CuO-CeO2 catalysts.The ranking order of the preparation methods of the catalysts in the soot oxidation performance is as follows: sol-gel urea nitrate combustion Urea gelation method thermal decomposition co-precipitation.
