Description
本願は、「NOX選択的触媒還元効率の改善されたゼオライト触媒」をタイトルとする2005年12月14日に出願された米国仮出願60/750,261の優先権主張を伴うものである。
2NO2+4NH3+O2→3N2+6H2O (2)
NO+NO2+NH3→2N2+3H2O (3)
本発明によれば、ゼオライトは、まず金属イオン交換により金属で処理される。一般に、何れの公知金属を、1種単独で用いても良く2種以上併用してもよい。例えば、本発明のゼオライトを、バナジウム(V)、クロム(Cr)、マンガン(Mn)、鉄(Fe)、コバルト(Co)、ニッケル(Ni)、銅(Cu)及びセリウム(Ce)からなる群から選ばれる金属イオンでイオン交換することができる。ある実施様態においては、ゼオライトYと銅の使用が好ましい。しかしながら、当業界の熟練者には理解できるように、上述のような他の金属イオンや他のゼオライトも銅とゼオライトYに代えて使用可能である。
未反応アンモニアの排出が起こることもある。混合不足によりガス流中に高アンモニア濃度の流路ができるが、特に複数の微細な平行ガス流路を持つ耐火性ボディーに収納したモノリスハニカム型の担体の触媒を使用する場合には、粒状触媒の床の場合とは異なり流路間でガスの混合の可能性がないため、このような流路ができる懸念が大きい。したがって、窒素酸化物の選択的触媒還元の触媒のために使用される触媒が、酸素とアンモニアの反応を触媒して、効果的に過剰または未反応のアンモニアをN2及びH2Oに酸化することが望ましい。
(実施例1)
触媒A.
銅ゼオライトYの合成
低ナトリウムY(Na2O<2.4質量%)のアンモニウム型を、銅で次のように処理した:
B.攪拌を続けながら、工程Aのスラリーを80℃に加熱し、一時間保持し、その後冷却した。溶液のpHは調整しなかったが、反応中2.75〜3.5の範囲であった。
C.冷却した工程Bのスラリーを真空濾過して、液体から固形分を分離し、固形分を、分離された液体と同量の脱イオン水で洗浄した。
D.工程Cの粉末を4時間90℃の空気中で乾燥し、銅処理ゼオライトY粉末(CuY)を得た。
E.工程DのCuYを、工程Aのものと同一の銅溶液に再スラリー化(連続的に攪拌しながら)し、その後、工程B〜工程Dを五回交換を繰り返した。各々の交換のpHは、いずれの反応も2.75〜3.5であった。
F.最終の交換の後、粉末を16時間90℃の空気中で乾燥し、銅処理ゼオライトY粉末(CuY)を得た。
G.工程FのCuYは、16時間640℃でか焼した。化学分析の結果、このCuY粉末が、4.89質量%のCu(揮発分非含有の金属酸化物として)と0.41質量%Na2Oを含んでいることがわかった。
H.次いで、か焼したCuYを、10%水蒸気の空気中で800℃で50時間水熱処理した。これを触媒Aと称する。
触媒B.
銅ゼオライトYの合成
低ナトリウムY(Na2O<2.4質量%)のアンモニウム型を、銅で次のように処理した:
B.攪拌を続けながら、工程Aのスラリーを80℃に加熱し、一時間保持し、その後冷却した。溶液のpHは調整しなかったが、反応中3〜4の範囲であった。
C.冷却した工程Bのスラリーを真空濾過して、液体から固形分を分離し、固形分を分離された液体と同量の脱イオン水で洗浄した。
D.工程Cの粉末を4時間90℃の空気中で乾燥し、銅処理ゼオライトY粉末(CuY)を得た。
E.工程DのCuYを、工程Aのものと同一の銅溶液に再スラリー化(連続的に攪拌しながら)し、その後工程B〜工程Dを二回、それぞれ1時間行った。各々の交換のpHは、いずれの反応も3〜4であった。
F.最終の交換の後、粉末を16時間90℃の空気中で乾燥し、銅処理ゼオライトY粉末(CuY)を得た。
G.工程FのCuYは、16時間640℃でか焼した。化学分析の結果、このCuY粉末が、4.75質量%のCu(揮発分非含有の金属酸化物として)と0.1質量%Na2Oを含んでいることがわかった。
H.か焼したCuYを、次いで、10%水蒸気の空気中で800℃で50時間水熱処理した。これを触媒Bと称する。

D.工程Cの粉末を4時間90℃の空気中で乾燥し、銅処理ゼオライトY粉末(CuY)を得た。
E.工程DのCuYを、工程Aのものと同一の銅溶液に再スラリー化(連続的に攪拌しながら)し、その後、工程B〜工程Dを二回繰り返した。二回目の交換の際のpHは、いずれの反応も3〜3.5であった。
F.最終の交換の後、粉末を16時間90℃の空気中で乾燥し、銅処理ゼオライトY粉末(CuY)を得た。
G.工程FのCuYは、16時間640℃でか焼した。化学分析の結果、このCuY粉末が、4.3質量%のCu(揮発分非含有の金属酸化物として)と0.1質量%Na2Oを含んでいることがわかった。
H.か焼したCuYを、次いで、10%水蒸気の空気中で800℃で50時間水熱処理した。これを触媒Dと称する。
実施例4と実施例5の銅ゼオライト触媒を用いて、約2〜2.5g/in.3の量でハニカムに塗布した。試験室反応器において、これらの触媒のNOXのNH3SCR還元性能を試験した。The供給ガスは、窒素中に500ppmのNOX(NOとして添加)と500ppmのNH3と5体積%の水と10体積%のO2を含んでいた。空間速度GHSVは、80,000h-1であった。図2は、ゼオライト空孔から骨格外アルミニウムを除去することが重要であることを示している。骨格外アルミニウムが除かれない場合には水蒸気養生後に触媒の不活性化が見られ、骨格外アルミニウムがゼオライト空孔から除かれると触媒性能が改善した。骨格外アルミニウムのゼオライト空孔中における好ましくない残存レベルを決めるのに、実施例7と実施例8で作成したデータを使用した。表1は、触媒の水熱安定性のために必要な骨格外アルミニウムの限度を示すX線回折(XRD)データ及びX線光電子分光法(XPS)データである。
