Description Potassium and strontium substituted praseodymium
manganate type perovskite catalyst coated on
ceramic foam filters have been studied for diesel particulate
removal. The synthesized catalyst coated filter pieces have
been characterized by using XRD, SEM and TG analysis,
whereas their catalytic activity towards soot oxidation was
tested using a bench scale facility with real diesel engine
exhaust. The catalyst coated filters decrease the soot oxidation
Tinitial value by 150 �C and Tfinal by 100 �C as
compared to bare soot oxidation reaction, which can be
considered as high activity under the actual conditions of
diesel engine. The catalytic materials show good thermal
stability, while their low cost will also add to their potential
for practical applications. Although perovskites have been
studied for laboratory evaluations of catalytic soot oxidation,
present results further substantiate the possibility of
using low-cost, supported, non-noble metal based catalysts
for diesel exhaust emission control applications, especially
for the cost-effective retrofitment of in-use vehicles with
old generation engines.
