Description
1つもしくは複数の実施形態に従って、触媒のための基材は、自動車触媒を調製するために典型的に使用されるそれらの材料のいずれでもあり得、金属またはセラミックのハニカム構造を典型的に含むであろう。通路が流体流動に対して開くように、基材の入口面から出口面へと延在する、複数の微細で平行のガス流路を有するモノリスフロースルー型基材等の、あらゆる好適な基材が用いられ得る。それらの流体入口からそれらの流体出口まで本質的に直線路である通路は、壁によって画定され、通路を通って流れるガスが触媒材料に接触するように、触媒材料は「ウォッシュコート」としてコーティングされる。一体化基板の流路は、台形、長方形、正方形、正弦曲線、六角形、長円形、円形等のいずれの好適な断面形状でもあり得る薄壁チャネルである。かかる構造は、断面積の1平方インチにつき約60〜約1200以上のガス入口開口部(すなわち、「セル」)(cpsi)を含有し得る。代表的な市販のフロースルー型基材は、Corning400/6菫青石物質であり、それは菫青石から構築され、400cpsiおよび6ミルの壁厚を有する。しかしながら、本発明は、特定の基材タイプ、物質、または幾何学構造に限定されないことが理解されるであろう。
本発明の1つもしくは複数の実施形態に従って、SCR機能を触媒するのに有効な成分(本明細書で「SCR成分」と称される)は、NOx低減触媒組成物の一部として、ウォッシュコートにおいて活用される。典型的に、SCR成分は、ウォッシュコート内に他の成分を含む組成物の一部である。しかしながら、1つもしくは複数の実施形態では、NOx低減触媒組成物は、SCR成分のみを含んでもよい。
本発明の1つもしくは複数の実施形態に従って、NH3酸化機能を触媒するのに有効な組成物(本明細書で「NH3酸化成分」と称される)は、NOx低減触媒において活用される。排気ガス流内に含まれるアンモニアは、NH3酸化成分上の酸素と反応させられ、反応式1に従う触媒上でN2を形成する。
1つもしくは複数の実施形態に従って、SCR成分およびNH3酸化成分は、ウォッシュコート層内に適用され得、この層は基材上にコーティングされ、基材に付着させられる。
触媒を調製する方法
本発明の別の態様は、エンジンの排気ガス流内で産生される排出物を処理する方法を含む。排気ガス流は、NOx、CO、炭化水素、およびアンモニアのうちの1つもしくは複数を含み得る。1つもしくは複数の実施形態では、この方法は、アンモニアまたはアンモニア前駆体を排気ガス流に注入することと、次いで排気ガス流を、SCR機能によってNOxを除去するために、本明細書に記載される上流SCR帯を最初に通過させることとを含む。かかる実施形態では、排気ガス流は、NH3酸化機能によってアンモニアを除去するために、次いで下流AMOx帯を通過させられる。下流触媒帯はまた、アンモニアに加えて、CO、炭化水素のうちの1つもしくは複数を酸化させる機能を果たしてもよい。
表1に記載される通り、一連の触媒1A〜1Iを調製した。触媒の全ては、400cpsiのチャネル寸法および6ミルの壁厚を備える、円筒形1.0インチOD×3.0インチ長の菫青石ハニカムモノリス上に配置された粉末からなる。Pt(OH)6 2-のpH9.5での初期湿潤含浸によって、最初にPt(IV)をγ−アルミナ(SBA−150)上に固定化することによって、これらの触媒を調製し、続いて酢酸を用いて固着化を行った。得られた黄色の固体は、不揮発性の固体ベースで、約0.58質量%のPtを含有した。固体を、脱イオン水中で懸濁させ、粒径を縮小させるために、連続的ミルを通過させた。モノリス基材を得られたスラリーに浸漬し、排水し、過剰のスラリーを、チャネルを通して圧縮空気を吹き付けることによって除去した。モノリス試料を乾燥させ、450〜600℃で焼成した。Al2O3上のPtのみからなる、比較試料1Aおよび1Bを、この時点で取り置いた。鉄または銅交換ゼオライトを脱イオン水中で懸濁し、粒径を縮小させるために、懸濁液を粉砕した。上述の通り、担持Ptウォッシュコートがすでに適用されているモノリスを、得られたスラリーに浸漬し、排水し、過剰のスラリーを圧縮空気によって除去した。モノリス試料を乾燥させ、450℃で焼成し、層状触媒1C〜1Gおよび1K〜1Mを得た。SBA−150スラリー上のPtと、適切な金属交換ゼオライトスラリーとを所望の割合で混合させること、および新鮮なモノリスを混合されたスラリーに浸漬することによって、均一の触媒1H、1I、および1Nを作製した。コアを乾燥させ、次いで450℃で焼成した。
表1に記載される通り、一連の触媒1K〜1Nを調製した。触媒の全ては、400cpsiのチャネル寸法および6ミルの壁厚を備える、円筒形1.0インチOD×3.0インチ長の菫青石ハニカムモノリス上に配置された粉末からなる。上述の方法と全く同一の方法で、γ−アルミナ下塗り層上のPtを調製し、1K〜1Nに塗布した。不揮発性固体ベースで1.5質量%のFeを含有し、SAR=30を有するFeBEAを、CuCHA物質で置換したことを除いて、上述の通り、被覆層をCuCHA被覆層のために1K〜1Mに塗布した。SBA−150スラリー上のPtと、FeBEAスラリーとを所望の割合で混合させることによって、均一の触媒1Nを作製し、新鮮なモノリスを混合されたスラリーに浸漬し、続いて乾燥させ、450℃で焼成した。
表1で別様に指摘される場合を除いて、分析または評価の前に、触媒の全てを、750℃の空気中で5時間熱エージングした。熱触媒のエージングは、箱形炉内で行われた。エージングプロトコルは、二重目的を果たす。最初に、触媒活性が、複数の評価の実施にわたって変化しないような条件下でのみ、有意義な評価結果を獲得することができる。熱アニーリングは、触媒が熱変化に対して定常状態にあることを保証する。第2に、長期間の実地使用後の触媒活性が十分であることを保証するために、車両の耐用期間の妥当な割合をモデル化した熱的条件下で、触媒を評価した。
図2で例示される図表に基づき、SCRおよびAMOxを統合した触媒1Pを産生した。簡潔に言えば、400cpsiおよび6ミルの壁厚を有する1.0インチOD×6.0インチ長ハニカムモノリス基材を、一端上に1.25インチ長帯として、SBA−50上に担持された0.57質量%のPtを含有するスラリーでコーティングし、続いて450℃での乾燥および焼成を行った。スラリー調製プロセスは、上述の通りであった。この帯における標的ウォッシュコート装填量は、0.5g/in3であったが、これはこの帯における5g/ft3の標的Pt装填量をもたらす。図2Aで示される通り、得られた部分は、一端のγ−アルミナ帯上にPtを有する。次いでこの同一の部分を、上述のスラリー調製およびコーティングプロセスを用いて、反対端からCuCHAを含有するスラリーでコーティングし、この部分全体で2.5g/in3のCuCHAの装填量を得た。この部分を乾燥させ、次いで450℃で焼成し、CuCHA触媒をこの部分に固定した。図2bで示される通り、このプロセスにより、2つの帯を有する部分を得た:1)2.5g/in3のCnCHAのみを有する、長さ4.75インチのSCRのみの帯;2)下塗り層としてSBA−150上に0.5g/in3のPt、および上塗り層として2.5g/in3のCuCHAを有する、長さ1.25インチのAMOx帯。この部分は、統合コーティングプロセスによって生成されるSCR+AMOx触媒についての研究室規模のモデルとして機能する。1.0インチOD×6.0インチ長のハニカムモノリス基材を、γ−アルミナ下塗り帯上にPtを有することなく、この部分の全長にわたり2.5g/in3のCuCHAでコーティングすることによって、比較触媒Qを生成した。触媒組成および幾何学構造の詳細については表2を参照されたい。
