a)チャバザイト(CHA)ゼオライトと銅金属前駆体および鉄金属前駆体とを溶液中で接触させ、でイオン交換された鉄前駆体および銅を含有する固体CHAゼオライト材料を形成する工程;
b)固体材料を乾燥させ、鉄および銅金属前駆体を含有する乾燥CHAゼオライト触媒を得る工程;ならびに
c)鉄および銅金属前駆体を含有する触媒を含有する乾燥CHAゼオライト触媒をか焼し、触媒を活性形態に転化させる工程
を含む、方法を提供する。
SRC組成物は、チャバザイト(CHA)ゼオライト担体上でイオン交換された銅と鉄との組み合わせを含む。特定の実施形態において、チャバザイト(CHA)ゼオライト担体上でイオン交換された銅と鉄との組み合わせは、対応する金属酸化物の質量比として表される。いくつかの実施形態において、そのように明示される酸化銅と酸化鉄の質量比は、約1:10〜約10:1、より典型的には約1:3〜約3:1の範囲である。銅および鉄成分の濃度は変動し得るが、金属酸化物として計算した場合、典型的にはゼオライト担体材料の質量に対して約0.1〜約12質量%となる(例えば、最終金属イオン交換ゼオライト担体組成物に対して約6〜約8質量%)。いくつかの実施形態において、ゼオライト中に存在する鉄は、酸化鉄(Fe2O3)として計算した場合、最終金属イオン交換ゼオライト組成物の約0.01〜約6.0質量%、好ましくは最終金属イオン交換ゼオライト組成物の約0.5〜約4.5質量%、より好ましくは最終金属イオン交換ゼオライト組成物の約1〜約3.5質量%の量である。別の実施形態において、銅は、酸化銅(CuO)として計算した場合、最終金属イオン交換ゼオライト組成物の約0.01〜約6.0質量%、好ましくは最終金属イオン交換ゼオライト組成物の約0.5〜約5.0質量%、より好ましくは最終金属イオン交換ゼオライト組成物の約1〜約4質量%の量で前記ゼオライト中に存在する。これらの新しく形成されたゼオライト担体は、金属促進担体、ここでは鉄促進担体および/または銅促進担体と呼ばれることが多い。さらに、これらの金属イオンは、担持された金属イオン、例えば、担持された鉄および銅である。したがって、用語「イオン交換された」と「担持された鉄および/または銅」は、互換的に使用することができる。
1つ以上の実施形態によれば、触媒物品組成物(すなわち、SRC触媒組成物)用の基材は、自動車用触媒の製造に典型的に使用される任意の材料で構成されてもよく、典型的に金属またはセラミックハニカム構造を含む。基材は典型的に、触媒物品(すなわち、SRC触媒)ウォッシュコート組成物が適用され付着する複数の壁面を提供し、それによって触媒組成物の担体として機能する。
金属イオン交換ゼオライト材料の製造は典型的に、金属前駆体溶液による粒子形態のゼオライト担体材料のイオン交換プロセスを含む。複数の金属前駆体(例えば銅および鉄)が、同時にまたは別々にイオン交換され、同じ外部溶液を使用してイオン交換され、同じ担体粒子上でイオン交換される。例えば、CHAゼオライト粒子が担体粒子として使用される。
上記の触媒組成物は、担体内でイオン交換される金属成分の組み合わせを含有する担体粒子の形態で、ハニカム型基材などの触媒基材をコーティングする目的で水と混合されてスラリーを形成する。スラリーは、触媒粒子に加えて、任意に、結合剤としてのアルミナ、水溶性または水分散性安定剤(例えば、酢酸バリウム)、促進剤(例えば、硝酸ランタン)、会合性増粘剤、および/または界面活性剤(アニオン性、カチオン性、非イオン性または両性界面活性剤など)を含んでよい。
本発明はまた、本明細書に記載のSRC触媒組成物(すなわち、触媒物品)を組み込んだ排出物処理システムを提供する。本発明のSRC触媒組成物は典型的に、排出ガス排出物、例えばディーゼルエンジンからの排出ガス排出物を処理するための1つ以上の追加の構成要素を含む統合排出物処理システムにおいて使用される。例えば、排出物処理システムは、触媒化スートフィルター(CSF)構成要素および/または選択的ディーゼル酸化(DOC)触媒物品をさらに含んでよい。本発明のSRC触媒は典型的に、スートフィルターの上流または下流、およびディーゼル酸化触媒成分の下流に配置されるが、排出物処理システムの各種構成要素の相対的配置は変えることができる。処理システムは、アンモニア前駆体用還元剤注入器などの構成要素をさらに含んでもよく、任意に追加の粒子濾過構成要素、NOx貯蔵および/または捕集構成要素を含んでもよい。前述の構成要素のリストは単なる例示であり、本発明の範囲を限定するものと解釈されるべきではない。
最低実用温度(540℃以下)でNa型チャバザイトゼオライトをか焼し、骨格外アルミニウム種および/または歪んだアルミニウムサイトの形成を排除または最小化し、乾燥か焼Na型チャバザイトゼオライトを得ることによって、乾燥Na型チャバザイトゼオライトを製造した。
500ppmのNO、500ppmのNH3、10%のO2(容積)、5%のH2O(容積)の供給ガス混合物を添加し、実施例1のコアを含有する定常状態反応器(steady state reactor)に対してN2をバランスさせることにより、新規触媒コアの窒素酸化物選択接触還元(SCR)効率を測定した。
