Oxidation of Diesel Soot by Several Rear Earth Catalysts with Different Atmosphere

Diesel soot is related to incomplete fuel oxidation, and possesses the well-known mutagenic effects on human health.Diesel soot was collected from diesel engines and oxidized in laboratorial micro reactor by several prepared rare earth-based catalysts with or without different harmful monoxide gases such as NO, and activities of several rare earth catalysts were studied.The results indicate that soot can be more easily oxidized with monoxide gases.
