a)前項に従う反応器
b)水性媒体に酸化窒素を吸収させるための吸収装置、及び所望により
c)酸化窒素を接触還元するための還元装置、
をa)、b)、c)の順に含む。
製造例1
カンタル金属織布バンド(長さ100cm、幅3.7cm)、ドイツ製材料 構造コード番号1.4767(Montz GmbHより、D−40705 Hilden)、を900℃で4時間、空気なましし、その後、鋸歯状のホイールローラ(モジュール、0.1mm)で波形をつけ、そして、97cmの平坦な金属織布バンドと巻きあげを行い、鉛直方向に通路(channel)を有する直径が4.1cmのパックを形成した。このように得られたパックを懸濁液、(懸濁液は、100gのDisperal(登録商標)Al25(Sasolより)、100gの水、及び25gの触媒的に活性な粉末で構成されており、粉末の組成は、20質量%のZnO、16質量%のCuO、64質量%のAl2O3である)に含浸し、120℃で2時間乾燥させ、空気中において、950℃で熱処理した。含浸による焼きなまし後のパックの質量増加は、11.6%であった。
カンタル金属織布バンドを製造例1と類似の方法で処理した。この金属織布バンドの、長さが16.7cm、幅が2cmの部分に、鋸歯状のホイールローラ(モジュール、0.1mm)で波形をつけ、そして重ね合わせ、長さが7cmの直方形のモノリスを形成したが、モノリスは、鉛直方向に通路を有し、及び高さと幅が2cmで、3V2Aワイヤーで束ねたものである。このようにして得られたパックを懸濁液(懸濁液は、100gのDisperal(登録商標)Al25(Sasolより)、100gの水、及び25gの触媒的に活性な粉末で構成されており、粉末の組成は、20質量%のZnO、16質量%のCuO、64質量%のAl2O3である)に含浸し、120℃で2時間乾燥させ、空気中で900℃で12時間熱処理した。含浸による、焼きなまし後のパックの質量増加は、13.4%であった。
アンモニア濃度が12体積%であり、空気濃度が88体積%であるアンモニア−空気混合物中のアンモニアを、実験室装置においてPt/Rhネット上で反応させ、一酸化窒素を形成したが、この反応は、900℃で、ネットの領域1cm3当たりアンモニアの空間速度が36g/hのものであった。深さが10cmの製造例1の触媒層を、プラチナネットの近傍の下流に配置し、そして、反応ガスを、上述した触媒層を通し、800℃で約0.03sの滞留時間で流した。N2Oは、92体積%減少した。触媒床を横切っての圧力損失は、250mbarであった。
製造例2の触媒で、実施例1を繰り返した。N2Oは、90体積%減少した。触媒床を横切っての圧力損失は、192mbarであった。
プラチナネットの近傍の下流に配置した触媒の深さ10cmの層が、3mmの押し出し成形物の状態で、18質量%のCuO、20質量%のZnO、及び62質量%のAl2O3で構成されていること以外は、実施例1に類似した反応を行った。N2Oは、85体積%減少した。触媒床を横切っての圧力損失は、1450mbarであった。
6mmの押し出し成形物を使用して比較例1を繰り返した。N2Oは、80体積%減少した。触媒床を横切っての圧力損失は、1345mbarであった。
