Abstract
Description
図1に示す構成の脱硝試験装置を使用して排ガスの脱硝試験を行った。脱硝試験の手順は、次のとおりである。
ZSM−5(MFI)型ゼオライト(HSZ−830NHA、東ソー株式会社製)、およびイオン交換水、シリカゾル〔シリカドール(登録商標)、日本化学工業株式会社製〕を、重量比100:100:46で混合し、スラリーを得た。
得られた平板状基材を、温度80℃に加熱した30重量%の硝酸コバルト溶液5Lに6時間以上浸漬し、イオン交換により、ZSM−5(MFI)型ゼオライトにコバルトを担持させた脱硝触媒を作製した。
上記で得られた脱硝触媒について、図1にフロー図を示す脱硝試験装置を使用して排ガスについての脱硝触媒性能試験を行った。
ここで、表1における「Balance」は、ガス組成がトータルで100%になるように添加されるものを表し、NO、エタノール、水分以外のガス組成が空気(表中ではAirと表示)によって占められていることを示している。また、「面積速度」は下記の数式(I)より算出した。
面積速度=ガス流量/触媒幾何面積 …(I)
反応管(1)から出て、ライン(18)から取り出された処理済みガスのガス分析は、NOx計を用いて反応管(1)の出口NOx濃度を測定した。NOx計での測定値から、下記の数式(II)によって触媒のNOx除去性能である脱硝率を算出した。
得られた脱硝触媒性能の評価試験の結果を、下記の表2に示した。
上記実施例1の場合と同様にして、本発明の排ガス浄化方法に対応する脱硝触媒性能評価試験を、上記表1に示す試験条件とほぼ同様の条件で実施するが、上記実施例1の場合と異なる点は、実施例2〜8では、処理すべき原排ガスに、追加用水槽(21)からの定量送液ポンプ(22)の汲み上げ量を調整して、ライン(20)によってさらに水蒸気を添加し、水分調整排ガス中の水蒸気濃度が、原排ガス既存含有水蒸気および添加水蒸気の合計で4.9容量%(実施例2)、8.6容量%(実施例3)、10.1容量%(実施例4)、11.0容量%(実施例5)、14.0容量%(実施例6)、19.1容量%(実施例7)、および21.2容量%(実施例8)と、順次増加させた水分調整排ガスを、脱硝触媒層を具備する反応管(1)にそれぞれ供給した点にある。
参考のために、上記実施例1の場合と同様にして、触媒性能評価試験を実施するが、上記実施例1の場合と異なる点は、反応管(1)に導入する試験用の原排ガスを、ライン(4)からの空気、およびライン(5)からのNO/N2ガスを混合することにより調製し、原水槽(11)の定量送液ポンプ(12)および追加用水槽(21)の定量送液ポンプ(22)の作動をいずれも停止させて、水蒸気濃度0容量%の原排ガスを、脱硝触媒層を具備する反応管(1)に導入した点にある。そして、反応管(1)から出た処理済みガスのガス分析を、上記実施例1の場合と同様に行い、得られた脱硝触媒性能の評価試験の結果を、下記の表2にあわせて示した。
上記実施例1の場合と同様にして、本発明の排ガス浄化方法に対応する脱硝触媒性能評価試験を、上記表1に示す試験条件とほぼ同様の条件で実施するが、上記実施例1の場合と異なる点は、上記実施例1では、原排ガス中への水蒸気の添加を、燃焼排ガス中に液体状または気体状の水を導入して行ったのに対し、実施例9では、原排ガス中への水蒸気の添加を、燃焼排ガス中にエタノール水溶液を導入して行った点にある。そのために、図3にフロー図を示す脱硝試験装置を使用して排ガスについての脱硝触媒性能試験を行った。
