CATALYST CARRIER AND EXHAUST GAS PURIFYING CATALYST

摘要

The present invention relates to a catalyst carrier containing an apatite-type composite oxide, and proposes a catalyst carrier which is capable of increasing NOx removal performance by improving phosphorus poisoning. Proposed is a catalyst carrier which contains a composite oxide that is represented by composition formula (LaA)9.33-δB6O27.00-γ (wherein 0.3 ≤δ≤ 3.0; 0.0 < γ≤ 6.0; A represents elements including one or more elements selected from among Ba, Pr, Y, Sr, Mg and Ce; and B represents elements including one or more elements selected from among Si, P and Fe).
