Description
(1)外周壁と、前記外周壁の内側に配設され、ガス流れ方向入口側の端面から出口側の端面まで延びて流路を形成する複数のセルを区画形成する隔壁と、を有する柱状ハニカム構造部を備えるハニカム構造体と、
前記隔壁の内部に担持された触媒と、
前記ハニカム構造体内に設けられた磁性体と、
を有する誘導加熱用の触媒担体であって、
前記触媒担体の、少なくともガス流れ方向入口側の端面側に、前記触媒を担持しない領域Aを有し、
ガス流れ方向において前記磁性体が少なくとも前記領域Aに配置されている、誘導加熱用の触媒担体。
(2)(1)に記載の誘導加熱用の触媒担体と、前記触媒担体の外周に設けられたコイルと、を有する誘導加熱触媒システム。
図1は、本発明の実施形態における、触媒担体10のセル13の延伸方向に平行な断面模式図である。図2は、図1における触媒担体10のL1-L1断面の模式図である。
次に、本発明の実施形態に係る触媒担体の製造方法を説明する。まず、セラミックス製の隔壁を有し、隔壁によって複数のセルが区画形成されたハニカム構造体を作製する。例えば、コージェライトからなるハニカム構造体を作製する場合には、まず、坏土用材料としてコージェライト化原料を用意する。コージェライト化原料は、コージェライト結晶の理論組成となるように各成分を配合するため、シリカ源成分、マグネシア源成分、及びアルミナ源成分等を配合する。このうちシリカ源成分としては、石英、溶融シリカを用いることが好ましく、更に、このシリカ源成分の粒径を100~150μmとすることが好ましい。
まず、磁性粉体、及び、ガラス等で構成された固着材を混在させた材料で表面層形成用スラリーを作製する。具体的には、例えば、磁性粉体とガラス粉末を配合し、これにバインダ、分散剤、水を配合して表面層形成用スラリーを作製する。磁性粉体とガラス粉体の配合比としては、体積基準で1:1以上、20:1以下である。
磁性粉体と、金属又はガラスを主成分とする結合材とを含むスラリーをハニカム乾燥体のセル内に流し込み、当該金属の融点、又は、ガラスの軟化点以上の温度で加熱して固める。または、磁性粉体と、シリカ又はアルミナを主成分とする接着材料とを含むスラリーをハニカム乾燥体のセル内に流し込み、加熱してシリカ又はアルミナを固化する。
アルミナやシリカを主成分とする接着材料を用いる場合においては、スラリーをセル内に流し込む工程はハニカム成形、乾燥体の段階で行っても良い。この場合は、スラリーをハニカム成形体のセル内に流し込んだ後、ハニカム成形体を乾燥し、ハニカム乾燥体の焼成工程において、磁性体が接着材料に固定する工程が同時に行われる。シリカ又はアルミナは、乾燥により固化する効果を発現することが好ましい。
まず、磁性体を充填するハニカム乾燥体のセルの断面形状及びセルの長さを考慮して、所定の板状、棒状、ワイヤ状、または繊維状の磁性体を準備する。次に、ハニカム乾燥体の所定のセルに、上流側の端面から所定の長さまで磁性体を差し込むことで、セル内に磁性体を充填する。また、磁性体がリング状である場合は、ハニカム乾燥体の上流側の端面を所定の深さだけ切削除去して溝部を形成しておき、当該溝部にリング状の磁性体を差し込む。または、溝部を形成した生のハニカム成形体を作製しておき、これを乾燥させてハニカム乾燥体を作製した後、当該溝部にリング状の磁性体を差し込む。
図8に、本発明の実施形態における、誘導加熱触媒システム100のガス流れ方向に平行な断面模式図を示す。誘導加熱触媒システム100は、本発明の実施形態に係る触媒担体10、及び、触媒担体10の外周に設けられたコイル19を有する。
図9に、実施例1で準備した誘導加熱触媒システムのガス流れ方向に平行な断面模式図を示す。図9において、それぞれ、「SCR」は選択還元触媒を示し、「DOC」は酸化触媒を示し、「DPF」はディーゼルパティキュレートフィルターを示し、「CC-」はエンジン直下を示し、「UF」は床下を示す。
<初期条件>
・ハニカム構造体温度:300K
・初期アンモニア吸蔵量:CC-SCR、UF-SCR共に0g/L
<通電条件>
・誘電加熱方法:30kWの誘電加熱相当の熱量をCC-SCR全域に均一付与
・通電時間:FTP走行モード開始から500秒間
<供給排ガス条件>
・NH3濃度:入りガスNOx濃度の1.5倍になるように0~500秒で供給
比較例1として、実施例1に対し、CC-SCRの触媒配置領域をコージェライト担体のガス流れ方向の入口側の端面から出口側の端面まで全域に設けた以外は、同様の条件でシミュレーションを実施した。
参考例1として、比較例1に対し、CC-SCRに磁性体を配置せず、さらにCC-SCRの周囲にコイルを設けず、誘導加熱をしなかった以外は、同様の構成とした。そして、このような構成の参考例1のNOxエミッションを基準値100%とした。
実施例2として、実施例1に対し、CC-SCRのコージェライト担体のガス流れ方向において、前段と後段とに同じ距離だけ2等分し、前段にのみ実施例1と同様の磁性体及びコイルを設け、後段にのみ触媒を担持させた。
すなわち、実施例2のコージェライト担体は実施例1のコージェライト担体と同様であり、セルの延伸方向の長さが152.4mmである。また、後段の触媒配置領域のセルの延伸方向の長さが76.2mmである。ガス流れ方向において磁性体が配置されている領域Aは、コージェライト担体のガス流れ方向入口側の端面からコージェライト担体の長さの50%の位置まで配置されている。このように、実施例2のCC-SCRのコージェライト担体のガス流れ方向において、触媒が設けられた領域と磁性体が設けられた領域とが重なる部分αは無い。
また、誘導加熱の際の電力を10kWとした。それら以外は、実施例1と同様の条件でシミュレーションを実施した。
実施例3として、実施例2に対し、CC-SCRのコージェライト担体のガス流れ方向において、磁性体及びコイルを設けた領域を触媒配置領域へ22.9mmだけ延長して、触媒配置領域と磁性体が設けられた領域とが重なる部分αが触媒配置領域全体の30%となるようにした以外は、実施例2と同様の条件でシミュレーションを実施した。このとき、ガス流れ方向において磁性体が配置されている領域Aは、コージェライト担体のガス流れ方向入口側の端面からコージェライト担体の長さの65%の位置まで配置されている。
実施例4として、実施例2に対し、CC-SCRのコージェライト担体のガス流れ方向において、磁性体及びコイルを設けた領域を触媒配置領域へ38.1mmだけ延長して、触媒配置領域と磁性体が設けられた領域とが重なる部分αが触媒配置領域全体の50%となるようにした以外は、実施例2と同様の条件でシミュレーションを実施した。このとき、ガス流れ方向において磁性体が配置されている領域Aは、コージェライト担体のガス流れ方向入口側の端面からコージェライト担体の長さの75%の位置まで配置されている。
実施例5として、実施例2に対し、CC-SCRのコージェライト担体のガス流れ方向において、磁性体及びコイルを設けた領域を触媒配置領域へ60.96mmだけ延長して、触媒配置領域と磁性体が設けられた領域とが重なる部分αが触媒配置領域全体の80%となるようにした以外は、実施例2と同様の条件でシミュレーションを実施した。このとき、ガス流れ方向において磁性体が配置されている領域Aは、コージェライト担体のガス流れ方向入口側の端面からコージェライト担体の長さの90%の位置まで配置されている。
