定義
調製方法
アルカリ土類金属成分、及び担体材料としてヘテロ原子成分でドープされたアルミナを含む試料を以下の通り調製した。
触媒活性は、合成ガスベンチ活性試験(SCAT)を用いて求めた。試験される部品は、まずコアドリルを用いて中心を取り除かれ、水熱条件(水10%)を適用してオーブン内で750℃で5時間熟成された。熟成された中心部は、模擬触媒活性試験(SCAT)ガス装置内で表1の入口ガス混合物を用いて試験された。それぞれの場合において、残余分は窒素である。
測定の結果を図1に示す。図1は本発明の触媒の改善された活性を示しており、これらは、担持量150g/ft3で改質アルミナとバリウムの両方を含む。本発明の触媒は、バリウムを含まない比較例の触媒よりも低いCO T50ライトオフ温度を有する。これは、Pt:Pdの質量比が1:2-2:1の範囲の場合に特に顕著である。担体材料としての通常のアルミナ及びバリウムを含む触媒は、通常のアルミナを含みバリウムのない触媒と比べて、改善されたCO T50ライトオフ温度を示さない。
5%シリカでドープされたアルミナ、50g/ft3の総PGM担持量1:1の質量比のPt:Pd、及び様々な量のバリウムを含有する試料は、上述の方法を用いて調製された。CO T50ライトオフ温度も上述の同じ手順を用いて測定された。
調製方法
シリカでをドープしされたアルミナ粉末は、水中でスラリーにされ、d90が20ミクロン未満になるまで粉砕した。酢酸ストロンチウムがスラリーに加えられ、次いで、適量の可溶な白金塩及びパラジウム塩が加えられた。Pt:Pdの質量比は、50g/ft3の総PGM添加量で1:1であった。次に、スラリーを撹拌して均質化した。生じたウォッシュコートは、確立された被膜技術を用いて、1平方インチ当たり400セルを有するコーディエライトフロースルーモノリスに塗布された。部品は乾燥され、500℃でか焼された。CO T50ライトオフ温度も上述の同一の方法を用いて測定された。
調製方法
マグネシウムでドープされたアルミナ粉末は、水中でスラリーにされ、d90が20ミクロン未満になるまで粉砕した。酢酸バリウムがスラリーに加えられ、次いで、適量の可溶な白金塩及びパラジウム塩が加えられた。Pt:Pdの質量比は、50g/ft3の総PGM添加量で2:1であった。次に、スラリーを撹拌して均質化した。生じたウォッシュコートは、確立された被膜技術を用いて、1平方インチ当たり400セルのコーディエライトフロースルーモノリスに塗布された。部品は乾燥され、500℃でか焼された。
調製方法
触媒(5-1)は、酢酸バリウム溶液のインシピエントウェットネス含浸(により調製された。材料は105℃で乾燥された。次に、白金塩及びパラジウム塩の第2の溶液がインシピエントウェットネス含浸により加えられた。生じた材料は105℃で乾燥され、次いで500℃でか焼された。最終的な組成は、Pt0.65重量%、Pd0.35重量%、Ba10重量%であった。
