Studies on Catalytic Oxidation of Diesel Soot over Perovkite Oxides

Zusatztext

Diesel engines have been widely employed in heavy and light duty vehicles, locomotive, ships, etc. due to their high fuel efficiency, low cost, durability and reliability. The major drawback associated with them is the emission of significant amount of particulate matter (PM/soot) along with other pollutants. Apart from health problems, PM also causes pollution of air, water and soil, soiling of buildings, reductions in visibility impact agriculture productivity, global warming and climate change, etc. As the regulations on diesel engine emissions are becoming more stringent, engine modification and exhaust treatment are needed for improved emission control systems for PM.The DPF are becoming widespread as an effective measure to reduce soot emissions from diesel vehicles as they have filtration efficiencies of > 98%. Perovskite oxides have been extensively investigated as potential substitutes for costly PGM-based catalysts in automotive emission control. Thus, the objective of the present work is to develop an efficient catalyst for the active diesel soot combustion within the temperature range of diesel exhaust.
