ものである。
セラミック原料100質量%と、吸水後の平均粒径が20μm以上且つ吸水前で2質量%以上の吸水性ポリマーと、0.5質量%以上のジルコニアと、を含有する成形原料を混合して坏土とする原料混合工程と、
前記坏土をハニカム形状に成形してハニカム成形体を得る成形工程と、
前記ハニカム成形体を焼成して、流体の流路となる複数のセルを形成する多孔質の隔壁部を有するハニカム構造体を得る焼成工程と、
を含むものである。
14質量%以上のシリカゲルを含むセラミック原料100質量%と、吸水後の平均粒径が20μm以上且つ吸水前で2質量%以上の吸水性ポリマーと、を含有する成形原料を混合して坏土とする原料混合工程と、
前記坏土をハニカム形状に成形してハニカム成形体を得る成形工程と、
前記ハニカム成形体を焼成して、流体の流路となる複数のセルを形成する多孔質の隔壁部を有するハニカム構造体を得る焼成工程と、
を含むものである。
実施例1のハニカム構造体を、以下のように作製した。原料混合工程では、まず、セラミック原料として、コージェライト化原料を調整した。具体的には、平均粒径が10μmのタルク40質量%、平均粒径が5μmのカオリン8質量%、平均粒径が2μmの焼カオリン8質量%、平均粒径が5μmのアルミナ20質量%、平均粒径が1μmの水酸化アルミニウム9質量%、平均粒径が4μmの石英15質量%を混合してコージェライト化原料を調整した。このコージェライト化原料100質量%に対して、吸水後の平均粒径が20μmの吸水性ポリマーを吸水前で6.0質量%、平均粒径1.0μmのジルコニア1.5質量%、バインダーとしてのメチルセルロース及びヒドロキシプロポキシルメチルセルロースを5.6質量%、界面活性剤0.5質量%、水81質量%を添加して成形原料とし、これを混合して混合して杯土を得た。なお、吸水性ポリマーは、粒子状のポリアクリル系アンモニウム塩であり、吸水倍率が15〜25倍で、吸水後の平均粒径が上記の値(20μm)となるものを使用した。
成形原料の平均粒径や配合割合,及びセル構造を表1に示すように変更した以外は実施例1と同様にして、実施例2〜13,比較例1〜13のハニカム構造体を作製した。なお、表1中の[−]は、その材料を成形原料に添加していないことを意味する。また、実施例9〜11,13及び比較例12では、石英の代わりに平均粒径12μmのシリカゲルを、表1に示す割合で添加した。比較例4では、石英の代わりに平均粒径15μmの溶融シリカを添加した。
実施例1〜13,比較例1〜13について、気孔率、平均細孔径、濡れ面積割合Rを測定した。気孔率及び平均細孔径は、水銀ポロシメーター(マイクロメトリックス社製オートポアIV9520)で測定した。濡れ面積割合Rは、上述した方法により測定した。結果を表1に示す。なお、表1には、濡れ面積Sの値も合わせて示した。
実施例1〜13,比較例1〜13のハニカム構造体の隔壁部に、触媒を担持させる触媒担持工程を行った。触媒としては、ZSM−5ゼオライトを用いた。触媒量(g/L)は、表1に示す値となった。
触媒担持後の実施例1〜13,比較例1〜13について、上述した方法で触媒充填率を測定した。測定箇所は、ハニカム構造体の径方向に中心と端、全長方向に入口端面から1cm、出口端面から1cmの計6箇所とし、6箇所から各3試料ずつ取り出した。各試料についてSEMにて撮影した写真を元に、上述した画像解析により触媒部、気孔部を求め、触媒充填率=触媒部の画素数/(触媒部の画素数+気孔部の画素数)として求め、全試料の平均値として触媒充填率を算出した。結果を表1に示す。なお、SEM観察時の倍率は200倍とした。
触媒担持後の実施例1〜13及び比較例1〜13のハニカム構造体を、エンジンベンチにて2.2Lディーゼルエンジンの排気系に取り付け、エンジン回転数2200rpm、トルク45Nmの定常状態にて圧力損失(kPa)を求めた。圧力損失は、試料を取り付けエンジン始動後30分間暖気後に差圧計にて測定し、試料前後の差圧が十分に安定したところで10秒間測定し、その平均値として算出した。比較例1の圧力損失を基準(値1.0)として、比較例1の圧力損失に対する実施例1〜13及び比較例2〜13の圧力損失の比を圧損比として算出した。そして、圧損比が値1.2以下の場合を良好、1.2超過の場合を不良と判定した。結果を表1に示す。
ディーゼルエンジン(8L/6気筒)を備えた尿素SCRシステムを用いてNOx浄化率の評価を行った。実施例1〜13及び比較例1〜13のハニカム構造体へ排ガスとNOx浄化に必要な尿素を流通させ、ハニカム構造体の前段及び後段のNOx量を測定し、(後段のNOx量)/(前段のNOx量)×100としてNOx浄化率(%)を算出した。NOx浄化率測定は、測温位置をハニカム構造体の入口端面から20mm手前としたときの排ガス温度を250℃とし、排ガス流量を380kg/h、NOx/NH3当量比が1.0となる条件で行った。そして、NOx浄化率が90%以上の場合を良好、90%未満の場合を不良と判定した。結果を表1に示す。
