市販のベータゼオライトを、Fe(NO3)3の水溶液に撹拌しながら添加した。混合後、結合剤およびレオロジー改質剤を添加してウォッシュコート組成物を形成した。
比較的高い粒度分布で粉砕したアルミナ粒子、硝酸白金、結合剤およびレオロジー改質剤の混合物を脱イオン水中に含むウォッシュコート組成物を調製した。チタン酸アルミニウムウォールフローフィルタを、本出願人/譲受人の国際公開第2011/080525号に開示される方法および装置を用いて、0.2g/in3のウォッシュコート添加量の触媒組成物で、最終の総Pt添加量5g/ft3でコーティングした、この際、上流側への配向が意図される第1の端部の流路を、その全長の75%について硝酸白金および微粒子アルミナを含むウォッシュコートでその意図される上流端部からコーティングし;かつ、反対側の端部の、下流側への配向が意図される流路を、その全長の25%について入口流路と同じウォッシュコートでコーティングする。つまり、この方法は次の:(i)ハニカムモノリス基材を実質的に垂直に維持するステップ;(ii)予め決定された量の液体を基材の下端で流路の解放端部を介して基材に導入するステップ;(iii)基材内に導入された液体を密封しながら維持するステップ;(iv)維持した液体を含有する基材を反転させるステップ;および(v)反転した基材の下端で基材の流路の解放端部に真空を適用し、基材の流路に沿って液体を引き入れるステップを含んだ。触媒組成物を、第1の端部からフィルタ流路にコーティングし、その後コーティングされたフィルタを乾燥させた。次に、第1の端部からコーティングした、乾燥したフィルタを回転させ、この方法を繰り返して第2の端部から同じ触媒をフィルタ流路にコーティングし、その後乾燥およびか焼した。
400セル/平方インチのコージェライトフロースルー基材モノリスを、本出願人/譲受人の国際公開第99/47260号に開示される方法を用いて、微粒子アルミナを含む水性スラリーでコーティングした。2つの異なるウォッシュコート添加量:1番(実施例3Aと命名)1.0g/in3;および2番(3B)0.4g/in3を調製するように固体含量を選択した。結果として生じる部分を乾燥させた後、か焼した。
400セル/平方インチのコージェライトフロースルー基材モノリスを、本出願人/譲受人の国際公開第99/47260号に開示される方法を用いて、微粒子セリア:ジルコニア混合酸化物を含む水性スラリーでコーティングした。2つの異なるセリア:ジルコニア混合酸化物材料を使用した。1番(実施例4Aと命名)のセリア:ジルコニア重量比は9:1であった;一方、2番(4B)のセリア:ジルコニア重量比は1:9であった。両方のセリア:ジルコニア混合酸化物を、1.0g/in3のウォッシュコート添加量でフロースルー基材モノリスの上にコーティングした。結果として生じる部分を乾燥させた後、か焼した。
コア切断の前に実施例4Aおよび4Bに従って調製したサンプルに、硝酸パラジウムの水溶液を含浸させた(それぞれ実施例5Aおよび5Bと命名)。次に、結果として生じる部分を乾燥させ、か焼し、直径1インチ(2.54cm)×長さ3インチ(7.62cm)のコアを各々の完成品から切断した。
コア切断の前にサンプル3Aに硝酸パラジウムの水溶液を含浸させた。結果として生じる部分を乾燥させ、か焼し、直径1インチ(2.54cm)×長さ3インチ(7.62cm)のコアを各々の完成品から切断した。
コーティングしたフィルタを、フィルタの入口流路および出口流路の両方に適用したウォッシュコートが硝酸白金に加えて硝酸パラジウムを含む点を除いて、比較例2と同じ方法を用いて調製した。入口および出口流路のウォッシュコート添加は、入口面および出口面の両方で5g/ft3Pt、5g/ft3Pdの添加量、すなわち10g/ft3の総PGM添加量に達するような方法で実行した。
コーティングしたフィルタを、フィルタの入口流路および出口流路の両方に適用したウォッシュコートが硝酸白金に加えて硝酸パラジウムを含む点を除いて、比較例2と同じ方法を用いて調製した。入口および出口流路のウォッシュコート添加は、入口面および出口面の両方で5g/ft3Pt、1g/ft3Pdの添加量、すなわち6g/ft3の総PGM添加量に達するような方法で実行した。
この試験は、図1に示される第1の合成触媒活性試験(SCAT)実験室反応器で実施され、そこでは実施例1のコーティングされたFe/ベータゼオライトSCR触媒の新鮮なコアが、比較例2(対照)の触媒化されたウォールフローフィルタのコアかまたは、その後に順に実施例3A、3B、4A、4B、5A、5Bまたは6のガード床コアが続く比較例2の新鮮なコアのいずれかの下流の導管に配置されている。合成ガス混合物を、30,000hr−1の触媒の排気量で導管に通した。炉を用いて触媒化されたウォールフローフィルタサンプルを900℃のフィルタ入口温度の定常状態の温度で60分間加熱(または「老化」)し、その間、入口SCR触媒温度を300℃に維持した。ガード床コアを比較例2コアのすぐ下流の炉に置き、900℃に加熱した(図1も参照)。空気(熱交換器)または水冷却機構を用いて、フィルタとSCR触媒との間の温度低下を生じさせた。老化の間のガス混合物は、O2 10%、H2O 6%、CO2 6%、CO 100ppm、NO 400ppm、C1としてのHC 100ppm、残量N2であった。
市販のアルミノケイ酸CHAゼオライトを、Cu(NO3)2の水溶液に撹拌しながら添加した。スラリーを濾過した後、洗浄し乾燥させた。この手順は、所望の金属添加量を実現するために繰り返すことができる。最終生成物をか焼した。混合後、結合剤およびレオロジー改質剤を添加してウォッシュコート組成物を形成した。
2つのディーゼル酸化触媒を以下の通り調製した:
単層DOCを以下の通り調製した。硝酸白金および硝酸パラジウムを、シリカ−アルミナのスラリーに添加した。ベータゼオライトをスラリーに添加して、それがゼオライトとしての固体含量の<30質量%を構成するようにした。ウォッシュコートスラリーを、実施例10の方法を用いて400cpsiフロースルー基材の上に添加した。添加した部分を乾燥させた後、500℃でか焼した。ウォッシュコート被膜中の総白金族金属添加量は、60gft−3であり、総Pt:Pd重量比は4:1であった。直径1インチ(2.54cm)×長さ3インチ(7.62cm)のコアを完成品から切断した。結果として生じる部分は、「新鮮な」、すなわち老化していないと記載され得る。
単層DOCを以下の通り調製した。硝酸白金および硝酸パラジウムを、シリカ−アルミナのスラリーに添加した。ベータゼオライトをスラリーに添加して、それがゼオライトとしての固体含量の<30質量%を構成するようにした。ウォッシュコートスラリーを、DOC Aに用いたものと同じ方法を用いて400cpsiフロースルー基材の上に添加した。添加した部分を乾燥させた後、500℃でか焼した。単層DOC中の総PGM添加量は、120g/ft3であり、Pt:Pd重量比は2:1であった。直径1インチ(2.54cm)×長さ3インチ(7.62cm)のコアを完成品から切断した。結果として生じる部分は、「新鮮な」、すなわち老化していないと記載され得る。
この試験は、図1に示される第1の合成触媒活性試験(SCAT)実験室反応器で実施され、そこでは実施例1のコーティングされたCu/CHAゼオライトSCR触媒の老化したコアが、(実施例11による)ディーゼル酸化触媒(DOC)AまたはBのいずれかのコアの下流の導管に配置された。合成ガス混合物を、6リットル/分の速度で導管に通した。炉を用いてDOCサンプルを900℃の触媒出口温度の定常状態の温度で2時間加熱(すなわち「老化」)した。水冷した熱交換器ジャケットを適宜使用することもできたが、SCR触媒は、DOCサンプルの下流に配置され、炉出口とSCR入口との間の管の長さを調節することにより、老化プロセスの間300℃の触媒温度で保持された。適切に位置する熱電対(T1およびT2)を用いて温度を決定した。老化の間に使用したガス混合物は、空気40%、N250%、H2O10%であった。
全体としてとらえると、実施例7および8および比較例2と併せて図4に示される実施例9の結果は、1:1〜5:1の間のPt:Pd重量比が、触媒を含有する白金族金属からの下流のSCR触媒への白金族金属、主に白金の揮発によるNOx変換活性の低下の問題を低下させる点で有用であることを示す;そして
