Title
(JA) リン化合物含有排ガス浄化用触媒
Abstract
(JA)

ガス流入側端面からガス流出側端面に沿って延在して設けられるとともに、ガス流入側端面からガス流出側端面まで貫通する複数のガス流路を区画形成する隔壁を有する耐火性三次元構造体と、隔壁上にガス流入側端面から連続して形成された、Pdを含む下触媒層と、隔壁上の最表面に位置し、ガス流入側端面から連続して形成された、Rhを含むガス流入側上触媒層と、隔壁上の最表面に位置し、ガス流出側端面から連続して形成された、Rhを含むガス流出側上触媒層とを有し、ガス流入側上触媒層及びガス流出側上触媒層は、ガス流路方向に沿って互いに離間するように配置されており、ガス流路方向に沿う下触媒層の長さは、15mm以上であり、当該長さの割合は、ガス流路の全長に対して、18%以上100%未満である、リン化合物含有排ガス浄化用触媒。
