Description
4NO+4NH3+O2→4N2+6H2O (1)
変換生成物は対応する水(H2O)と窒素(N2)である。化学的に見ると、この変換は、窒素酸化物のアンモニアによる窒素へのコンプロポーショネーション(comproportionation)に関する。
(a)炭素骨格中の窒素含有量が0.4重量%より大きく、
(b)1nm未満のミクロ孔の細孔容積が0.47cm3/g未満、及び、
(c)1nmを超えるマクロ孔の細孔容積が0.72cm3/g未満である。
基本的な考え方を確認する(improve)ために、まず、異なる窒素含有量と異なるミクロ及びマクロ孔容積を有する試料を製造した。そのため、1時間当たり、4mmの練炭成形品600kgを、8段流動層反応器に供給した。炉温は約900℃であり、流動化ガスは天然ガスを燃やして作り出した。1時間当たり300gの蒸気を、4mmの練炭成形品の部分的ガス化のために供給した。試料番号1及び2(比較例)は、窒素化合物を加えずに製造した。活性炭触媒の他の試料は、窒素化合物である尿素を(45%水溶液の形で)加えて製造し、この水溶液を流動層反応器に送り込んだ。
比較例及び本発明により製造された触媒の評価のために、一酸化窒素の変換率を試験装置で測定した。一酸化窒素の変換率は、温度120℃にて、モデル燃焼排ガス(一酸化窒素400ppm、アンモニア400ppm、酸素22体積%、及び水17体積%、残部(moiety)は窒素)を用いて測定する。
試料1及び2を、窒素化合物である尿素を加えずに作製した。一酸化窒素変換率は、42%(試料1)及び44%(試料2)と非常に低かった。試料2のミクロ及びマクロ孔容積は試料1より明らかに高かったけれども、測定した一酸化窒素変換率の増加は微量(測定精度の範囲内で)であった。
流動層反応器に尿素溶液を送り込むことによって、試料番号1−0.4%窒素、及び、1−0.8%窒素を得た。窒素含有量0.4重量%に対しては65%、窒素含有量0.8重量%に対しては71%の一酸化窒素変換率が測定された。
本発明に従い、流動層反応器に様々な量の尿素を供給することによって、窒素含有量を0.4、0.8及び1.5重量%へと増加させ、試料2−0.4%N、試料2−0.8%N、及び試料2−1.5%Nを作製した。炭素骨格中の窒素含有量が増加したことにより、一酸化窒素変換率が、67%、80%及び91%(1.5重量%窒素)へと改良された。
実施例4は、同一の窒素含有量での、ミクロ及びマクロ孔容積のさらなる増加は、一酸化窒素変換率の増加をもたらさないことを明確にするはずであったが、逆に、試料4−0.4%N、試料4−0.8%N、試料5−0.4%N、及び試料5−0.8%Nが証明するように、一酸化炭素変換率は、1nm未満のミクロ孔容積0.34cm3/g及び1nmを超えるマクロ孔容積0.45cm3/gから減少している。
実験室において、一酸化窒素と重金属を含むモデルガスを作り出すのは難しいため、次の方法を選択した。つまり、NOXに加え、重金属のヒ素及びホウ素を含んだ実際の排ガスから一酸化窒素を取り除くために、触媒試料2−0.8%Nをパイロット設備で使用した。12秒の滞留時間後、360ppmの一酸化窒素含有量を50ppmに減らすことができた。一酸化窒素試験装置での活性実験用の、ヒ素及びホウ素で様々に汚染された試料を得るために、それらを3日後(試料6.1.2−0.8%N)と9日後(試料6.2.2−0.8%N)の反応器の最初のガスレベルから取った。両試料からはかなりの量のヒ素及びホウ素が集められたが、触媒活性は、80%(初期の材料)から、それぞれ73%又は71%へとわずかに減少しただけであった。ヒ素865mg/kg、及びホウ素7185mg/kgの極めて高い重金属含有量(試料6.3.2−0.8%N)の後だけ、触媒活性が15%に落ちた。パイロット設備の最初のガス層中の重金属が沈着(precipitated)すると、45日後の純ガス中に含まれる一酸化窒素は、わずか50ppmであった。
