本発明を更に明確に理解できるように、次の図面を参照する。
(i)脱アルミニウム(dealumination)過程:スチーミング(steaming)及び酸(acid)又は錯化剤(例えば、EDTA(ethylenediaminetetracetic acid))を用いた酸抽出;酸及び/又は錯化剤処理;SiCl4のガススチーム処理(モレキュラーシーブ構造物内のAlをSiに取り替える);
(ii)カチオン交換過程-Laのような多原子価(muti-valent)カチオンの使用;及び、
(iii)リン(phosphorus)含有化合物の使用(例えば、米国特許第5,958,818号参照)
モレキュラーシーブ材料のサンプルがその構造と構成を決定するために得られ、テストされた。サンプルに対して、X線回折(XRD)パターンが銅Kα放射を用いてPANalytical X‘pert PRO MPD(Multi-Purpose Diffractometer)上で収集された。回折パターンが10mmの領域に照らされた一定のサンプルを維持するプログラム可能な分岐(divergence)と受領スリット(receiving slit)を用いて収集され、x線はリアルタイム多重ストリップ(RTMS)検出器を用いて測定された。DIFFaX分析がAEI/CHA連晶比を決定するために用いられた。DIFFaXは、パワー回折データシミュレーションに用いられるプログラムである。このプログラムは、国際ゼオライト協会又は著者Michael M.J. Treacy及びMichael W. Dean.から得ることができる。シミュレーションの生成のために用いられるバージョンは、DIFFaX 1.813.であった。シミュレーションの生成のために用いられた入力ファイルは、WO02/070407に説明されたものと同一であった。前記シミュレーションは、5〜120゜2θまで出力ファイルに適用される機構的拡大(instrumental broadening)とAEIに対するCHA層の任意分布により生成された。前記層の任意分布は、収集されたデータに対する比較のためにのみ用いられ、前記材料が任意に分布しているかを確認するのに用いられるものではない。
前記銅-含有10:90AEI/CHA連晶サンプルが72時間700℃で熱水的にエージングされた。前記エージングされた材料は、その後、モノリスハニカムコアにウォッシュコートとして塗布され、SCAT(Synthetic Catalyst Activity Test)リグ(rig)を用いてテストされた。前記テストは、シミュレートされたディーゼル排気ガスの条件下で(即ち、触媒を50,000/hrの空間速度でガスに露出)行われ、前記ガスの組成は、N2で約350ppmのNH3及びNO、約14重量%O2、約4.5重量%H2O、及び約5重量%CO2であった。テストの温度範囲は、200〜450℃であった。
