Document Type and Number:
Japanese Patent JP5897047
Kind Code:
B2
Abstract:
The present invention relates to a catalyst carrier comprising an apatite-type composite oxide and proposes a catalyst carrier capable of improving purification performance of NOx due to improvement of phosphorus poisoning. Proposed is a catalyst carrier which contains a composite oxide that is represented by a composition formula of (LaA) 9.33-´ B 6 O 27.00-³ (wherein, 0.3 ¤ ´ ¤3.0, 0.0 < y ¤ 6.0; "A" represents one or two or more elements selected from Ba, Pr, Y, Sr, Mg, and Ce; and "B" represents one or two or more elements selected from Si, P, and Fe).
