Abstract
Usual combustion of hydrocarbon takes place at high T (> 1500 °C). Therefore, the formation of pollutants (NOx, CO, partially unburnt HC) unavoidably occurs. The aim of the catalytic flameless combustion of hydrocarbons is the abatement of these pollutants.Supported noble metals (Pt, Pd, Rh) are catalysts characterized by high activity but they are expensive and with the tendency to sintering. Perovskite-type oxide mixtures are characterized by comparable activity, good durability and low cost. Therefore, they are good candidates as substitute for noble metals. This subject is deeply discussed.
