Summary:
【要約】【課題】排ガス中のHC,CO及びNOx を低温域から高温域まで効率よく浄化できるようにする。【解決手段】含まれるNOx をNOx 吸着材に吸着させて除去した排ガスを排ガス浄化用触媒と接触させて浄化する。NOx が除去された排ガスを排ガス浄化用触媒に接触させることにより、HC及びCOとO2との反応性が向上し、またNOx 吸着材は低温域でもNOx を吸着するため、低温域におけるNOx の排出が防止される。
Claim (excerpt):
含まれる窒素酸化物が除去された排ガスを多孔質酸化物に貴金属を担持してなる排ガス浄化用触媒と接触させることを特徴とする排ガス浄化方法。
