High temperature combustion catalyst

摘要

Disclosed herein is a high temperature combustion catalyst which comprises a stainless support containing 7 to 13 % in weight of aluminum and 0.01 to 2 % in weight of one or more metals selected from molybdenum. tungsten and niobium, and catalyst material loaded on the stainless support. In a conventional high temperature combustion catalyst prepared by loading catalyst material on a stainless support containing aluminum, the high temperature resistance does not reach to a completely satisfactory level so that the surface may be oxidized under severe conditions resulting in the deactivation. The aluminum and the molybdenum or the like of this invention form a protection film having a sufficient thickness on the surface of the metal support for protecting the metal support to obtain a longer life. <IMAGE>
