Description
(1)水銀蒸気と5〜1000ppmの硫黄酸化物を含むガスを活性炭100重量部にアルカリ金属ハロゲン化物のみを5〜70重量部添着させた吸着剤と接触させるガス中の水銀蒸気除去法、
(2)アルカリ金属ハロゲン化物が、ヨウ化カリウムまたはヨウ化ナトリウムである(1)記載のガス中の水銀蒸気除去法、
(3)吸着剤が活性炭100重量部にアルカリ金属ハロゲン化物のみを20〜70重量部添着させてなる(1)又は(2)記載のガス中の水銀蒸気除去法、
(4)水銀蒸気と50〜1000ppmの硫黄酸化物とを含むガスを活性炭100重量部にアルカリ金属ハロゲン化物のみを30〜70重量部添着させた吸着剤とを150℃以下で接触させる(1)又は(2)記載のガス中の水銀蒸気除去法、
である。
活性炭の液体窒素温度での窒素吸着等温線からCI法により求めた細孔容積は、0.3〜2.0ml/g、好ましくは0.5〜1.8ml/g、さらに好ましくは0.6〜1.5ml/gである。
活性炭の保水率は、通常30〜70%、好ましくは40〜70%である。
また、ハニカムを使用する場合には、そのセル数は特に限定されないが、通常は50〜1000セル/inch2、好ましくは150〜500セル/inch2のものが使用される。
活性炭に多量のアルカリ金属ハロゲン化物を添着する場合には、上記の添着の工程を複数回繰り返す、すなわち、一旦、添着した活性炭に再度アルカリ金属ハロゲン化物を含む水溶液を噴霧あるいは、活性炭にアルカリ金属ハロゲン化物を含む水溶液に含浸させ、活性炭を乾燥することにより吸着剤とすることができる。
排出ガスが5ppm以上の硫黄酸化物を含んでいると、その濃度の増加にともない水銀蒸気の吸着除去能は低下する。
本発明における水銀蒸気を含む処理ガス中の硫黄酸化物の濃度は、それが水銀蒸気の吸着を阻害し始める濃度、すなわち5ppm以上の場合に効果を発揮するが、通常5〜1000ppm、より効果的には5〜500ppmおよび50〜1000ppm、更に効果的には100〜200ppmの濃度で含むものである。ガス中の硫黄酸化物の含有量が1000ppmを超える様な高濃度で含まれている場合は、脱硫装置を用いて硫黄酸化物の濃度を低減するか、1000ppm以下となるように硫黄酸化物を含まない空気などで希釈するとよい。
本発明の方法においては、このガスの温度を、0〜150℃、好ましくは10〜80℃程度に調整しておくのがよい。ガスの相対湿度は0〜80%に調整しておくのが良い。
活性炭の形状が、破砕状、円柱状、球状の場合には、固定床で使用される。固定床の場合、活性炭を充てんした吸着塔に排ガスを流すことにより水銀蒸気を除去する方法がとられる。処理ガス中に粉塵がある場合には、活性炭が目詰まりするので、通常、電気集塵装置の後に設置される。本吸着剤は、水銀を効率的に除去するが硫黄酸化物を除去するものではないので、脱硫装置の前段、後段のどちらにおいても構わない。ただし、硫黄酸化物の濃度が1000ppm以上の場合には、脱硫装置の後段に置くのが好ましい。
活性炭の形状がハニカム状の場合、通常、固定床で使用される。ハニカム状の場合、ハニカム構造であるために目詰まりをおこし難い特徴を有しているため、電気集塵装置の前段に置くこともできる。

試験例1
25℃に保たれた恒温槽内に、〔図1〕に示される吸着性能測定装置を設置し、内径15.6mmのガラス製カラムに各吸着剤3.8mlを充填した。
上記試料充填カラムに、相対湿度70%、水銀蒸気濃度5mg/m3、SO2 5ppmを含むガスを、流量2.3L/分、線速度20cm/秒で流通させ、水銀の入口濃度に対する出口濃度を測定した。なお水銀蒸気濃度の測定は、ガステック製検知管水銀用No.40で測定した。
得られた結果から各試料の5%破過時間(処理前水銀蒸気濃度に対する処理後の水銀蒸気濃度の比が5%に達した時間、すなわちリークした水銀蒸気の濃度が入口濃度の5%に達した時間)を表1に示す。

試験例6
試験例1と同様の装置を用いて、相対湿度70%、水銀蒸気濃度5mg/m3、SO2 1000ppmを含むガスを、流量2.3L/分、線速度20cm/秒で流通させ、水銀の入口濃度に対する出口濃度を測定した。なお水銀蒸気濃度の測定方法は、試験例1と同じとした。得られた結果から各試料の5%破過時間を表1に示す。得られた結果から各試料の5%破過時間を表1に示す。

試験例7
試験1と同様の装置を用いて、相対湿度30%、水銀蒸気濃度5mg/m3を含むガス(SO2を含まず)を、流量2.3L/分、線速度20cm/秒で流通させ、各ガスの入口濃度に対する出口濃度を測定した。なお、水銀蒸気濃度の測定方法は、試験例1と同じとした。得られた結果から各吸着剤の5%破過時間を表に示した。
硫黄酸化物が共存しない系では、実施例3〜6の吸着剤は、比較例1〜4の吸着剤に比べて、長期間吸着性能を保持する結果となったが、吸着性能は実施例1〜2の吸着剤では、比較例1や4の吸着剤に比べて優れているものの、比較例2の吸着剤より劣っており、必ずしも優れた吸着特性を示す結果ではなかった。
試験例7に示すように、ヨウ化カリウムを5〜70部添着した吸着剤は、処理ガス中に二酸化硫黄が共存しない系においては、他の活性炭に比べ、水銀除去性能は優れているとは言えない水準であった。しかし、試験例1や試験例2のように処理ガス中に二酸化硫黄が共存する系においては、ヨウ化カリウムを5〜70部添着した活性炭は、他の活性炭に比べて、予想外の優れた水銀除去性能を示した。
特に50〜1000ppmの高濃度の硫黄酸化物が共存する系においては、ヨウ化カリウムを20〜70部添着した吸着剤は、他の吸着剤に比べて、極めて優れた水銀除去性能を示した。
また、比較例2〜4の吸着剤では、硫黄酸化物濃度の増加にともない、吸着性能が最大で1/25以下まで低下するのに対して、実施例の吸着剤では、吸着性能の低下は最大で1/6程度であり、硫黄酸化物が非共存の条件に比べて水銀蒸気吸着性能が向上しているものも見られた。なお、ヨウ素の担持量の少ない比較例1の吸着剤でも吸着性能の低下は見られないが、他の比較例や実施例の吸着剤に比べて除去性能が低いため実用的ではない。
