CATALYST FOR HIGH-TEMPERATURE COMBUSTION

摘要

PURPOSE:To obtain the titled catalyst for the high-temp. combustion of hydrocarbonic fuel having high activity and excellent resistance to heat and thermal shock by providing a single coating layer of a heat-resistant metallic oxide to a monolithic carrier, and depositing an active component such as platinum at the inside of the surface layer of said coatng layer. CONSTITUTION:A single coatin layer of an active heat-resistant metallic oxide such as alumina is provided to a monolithic carrier of cordierite, etc., and >=1 kind of active component selected from a group consisting of Pt and Pd is deposited at the inside of said coatig layer >=2mu off the surface layer to an amt. of 1-50g per 1l completed catalyst. The catalyst thus obtained has high activity and excellent resistance to heat and thermal shock without any increase in pressure drop, and the catalyst for the high-temp. combustion of hydrocarbonic fuel can be obtained.
