ABSTRACT:
A high temperature combustion catalyst for use in a catalytic combustion type gas turbine combustor and the like, having a superior low temperature ignitionability and a superior thermal durability at a high temperature, which comprises a porous carrier layer, a catalyst component such as palladium and platinum, and first, second and third promoter components, the latter four components being carried on the porous carrier layer, in which the first promoter component includes one of rare earth elements such as lanthanum, cerium, praseodymium and neodymium, alkaline earth metals such as barium, strontium and calcium, and oxides thereof, in which the second promoter component includes magnesium, silicon and oxides thereof, and in which the third promotor component includes one of heavy metals such as nickel, zirconium, cobalt, iron and manganese, and oxides thereof. A method for producing this high temperature combustion catalyst is also disclosed.
