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.

本文公开了一种高温燃烧催化剂,其包含含有7至13重量%的铝和0.01至2重量%的一种或多种选自钼的金属的不锈钢支撑体。 钨和铌,以及装载在不锈钢支架上的催化剂材料。 在通过将催化剂材料装载在含有铝的不锈钢支架上制备的常规高温燃烧催化剂中,耐高温性未达到完全令人满意的水平,使得表面可能在恶劣条件下被氧化,导致失活。 本发明的铝和钼等在金属支撑体的表面上形成具有足够厚度的保护膜,以保护金属载体以获得更长的寿命。
