    摘要: A catalyst carrier which includes a catalyst support layer containing an alkaline earth metal and/or an alkali metal disposed on an alumina substrate. The alkaline earth metal and/or the alkali metal is suppressed or prevented from diffusing into the substrate to react with alumina in the substrate. A catalyst support layer 3 that contains an alkaline earth metal and/or an alkali metal is formed on a surface of an alumina substrate 1 having a three-dimensional network structure. A zirconia layer 2 consisting of zirconia and/or stabilized zirconia is disposed between the substrate 1 and the catalyst support layer 3. The zirconia layer 2 has a thickness of 3 µm or more in a region of at least 65% of the substrate surface. The zirconia layer suppresses or prevents the alkaline earth metal and/or the alkali metal in the catalyst support layer from diffusing into the substrate.

    摘要: PROBLEM TO BE SOLVED: To provide a catalyst carrier where an alkaline earth metal and/or alkaline metal is prevented or suppressed from being moved to a substrate and reacting with alumina in the substrate in the catalyst carrier where a catalyst supporting layer containing the alkaline earth metal and/or alkaline metal is formed on a surface of the substrate of alumina matter. SOLUTION: Zirconia layer 2 comprising zirconia and/or stabilized zirconia is formed between the substrate 1 and the catalyst supporting layer 3 in the catalyst carrier where the catalyst supporting layer 3 containing the alkaline earth metal and/or alkali metal is formed on the surface of the substrate 1 of alumina matter having a 3-dimensional network structure. The thickness of the zirconia layer 2 is 3 μm or more in a region of 65% or more of the substrate surface. This zirconia layer allows the movement of the alkaline earth metal and/or alkaline metal in the catalyst supporting layer to be prevented or suppressed. COPYRIGHT: (C)2010,JPO&INPIT
