Description
以下の一般的な手順により、パラジウムは、PNA 1A(Pd/CHA)、比較PNA 1B(Pd/MFI)及び比較PNA 1C(Pd/BEA)を生じさせるように、26のシリカ対アルミナ比(SAR)を有する小細孔チャバサイト(CHA)ゼオライト、SAR=23を有する中細孔ZSM−5(MFI)ゼオライト及びSAR=26を有する大細孔ベータ(BEA)ゼオライトに加えられる:粉末触媒は、前駆体として硝酸パラジウムを使用してゼオライトのウエット含浸により調製される。100℃での乾燥後、試料は500℃でか焼される。試料は、その後、H2Oを10%含有する空気雰囲気中、750℃で、水熱的にエージングされる。3つの試料全てに対するPd充填量は、1重量%である。
PNA(0.4g)は、300Lhr−1g−1のMHSVで毎分2リットル流れるNO含有ガス混合物中で、2分間、約80℃の吸着温度で保たれる。この吸着段階の後に、更なる試験のために、貯蔵されたNOxの全てを触媒からパージするために、NO含有ガスの存在下、床温度が約400℃に達するまで、10℃/分のランピング速度で昇温脱離(TPD)が続く。試験は、その後、80℃の代わりに、170℃の吸着温度から開始して繰り返される。
PNA 1A及び比較PNA 1Dは、触媒のグラム毎に約64mgのSを加えるように、300℃で、それらをSO2含有ガス(100ppmのSO2、10%のO2、5%のCO2及びH2O、残部N2)と接触させることにより、高レベルのサルフェーションにかけられた。サルフェーション前後の触媒のNOx貯蔵容量は、実施例2の手順に従い100℃で測定される。結果は、表2に列挙される。
パラジウムは、実施例1の手順に従い、一連の小細孔モレキュラーシーブに加えられる。Pd充填量は、全ての試料に対して1重量%で保たれる。試料は、H2Oを10%含有する空気雰囲気中、750℃で、水熱的にエージングされる。エージングされた試料は、その後、実施例2の手順に従い、それらのNOx貯蔵容量について試験される。
パラジウムは、実施例1の手順に従い、小細孔モレキュラーシーブCHAに加えられる。Pd充填量は、試料に対して2重量%に増加される。試料は、H2Oを10%含有する空気雰囲気中、750℃で、水熱的にエージングされる。エージング試料は、実施例2の手順に従い、それのNOx貯蔵容量について試験される。試料上での、80及び170℃でのNOx貯蔵容量は、表4に列挙される。
