例1−触媒及び比較用触媒試料の製造方法
市販のBetaゼオライト上5重量%Fe触媒(5重量%Fe/Beta-比較例)は、下記のように調製した。5重量%Fe装填量を得るのに必要な量の硝酸鉄(Fe(NO3) 3.9H2O)を脱イオンH2O中に溶解させた。溶液の全体積は、単体試料の細孔容積に等しかった(初期的湿潤技術)。この溶液をBetaゼオライト材料に加え、得られた混合物を105℃で一晩乾燥させ、空気中、500℃で1時間か焼した。
ZrO2上5重量%Fe-15重量%W触媒(5%Fe-15%W/ZrO2-比較例)、CexZr1−xO2(x=0.2) 混合酸化物上5重量%Fe-15重量%W触媒(5%Fe-15%W/Ce0.2Zr0.8O2-本発明による)、CexZr1−xO2(x=0.5) 混合酸化物上5重量%Fe-15重量%W触媒(5%Fe-15%W/Ce0.5Zr0.5O2-本発明による)及び30重量%Ce0.75Zr0.25O2- Al2O3(ガンマアルミナ上に担持されたセリウム及びジルコニウム単一または複合酸化物−30%Ce0.75Zr0.25O2/Al2O3-本発明による) は、下記のように調製した。所望の5重量%Fe及び15重量%W装填量を得るのに必要な量の硝酸鉄(Fe(NO3) 3.9H2O)及びメタタングステン酸アンモニウムを脱イオンH2O中に溶解させた。溶液の全体積は、単体試料の細孔容積に等しかった(初期的湿潤技術)。この溶液を担体材料に加え、得られた混合物を105℃で一晩乾燥させ、次いで700℃で3時間か焼した。CexZr1−xO2(x=0.5) 混合酸化物上15重量%W触媒(15%W/Ce0.5Zr0.5O2-本発明による)は、含浸媒体中に鉄を含まない以外は、類似の様式で調製した。
それぞれ例1により調製したFe/Betaゼオライト及び5重量%Fe-15重量%W/ZrO2の1:1混合物は、2種類の材料を等比率で混合することにより、調製した。
例1及び2により調製した触媒の粉末試料は、本来の試料をペレット化し、それらのペレットを粉砕し、次いで得られた粉末を255〜350μm篩に通すことにより、得た。粉末試料をSynthetic Catalyst Activity Test (SCAT)反応器中に入れ、窒素系還元体を包含する下記の合成ディーゼル排ガス混合物(入口で)、すなわち100 ppmNO、100 ppmNO2、200 ppmNH3、12%O2、4.5%H2O、4.5%CO2、200 ppmCO、100 ppmC3H6、20 ppmSO2、残部N2を使用し、空間速度45,000hr−1(ガス流量毎分2リットル)で試験した。試料を5℃/分で加熱して150〜550℃に昇温し、排ガスの組成を検出し、NOx還元を促進する試料の活性を求めた。結果を添付の図に示す。
