Description
以下、本発明に係るダイオキシン吸着除去剤を実施例により説明する。
(実施例1)
以下に説明するように活性炭100gに軽油3gをコートし、これを100℃で5〜10時間乾燥することによりダイオキシン吸着除去剤を得た。
実施例1と同種の活性炭を比較例1のダイオキシン吸着除去剤とした。
得られた実施例1及び比較例1のダイオキシン吸着除去剤約10gずつを、それぞれ20mmφカラムに充填した。これらのカラムに、湿度を質量基準で30%に調整した空気ガスを温度25℃で、流量5L/分で流通させることにより飽和吸着させ、このときの平衡吸着量を測定した。ここで、平衡吸着量とは、前述の空気ガスを流通させた際にダイオキシン吸着除去剤の質量がほぼ一定になったときの質量と、空気ガス流通前のダイオキシン吸着除去剤の質量との差分を、空気ガス流通前のダイオキシン吸着除去剤の質量に対する百分率で表したものである。
得られた実施例1及び比較例1のダイオキシン吸着除去剤10gずつを、それぞれ20mmφカラムに充填した。これらのカラムに、塩化水素ガスを10体積%含み、湿度を質量基準で60%に調整した空気ガスを温度25℃で、SV(空間速度)6000/時間で1時間流通させた。続いて、塩化水素ガスの代わりにアンモニアガスを体積で200ppm含むこと以外には前述と同様な空気ガスを前述と同様の流通条件で12時間流通させた。ガス流通後のカラムの写真をそれぞれ撮影した。実施例1の吸着除去剤を充填したカラムの写真を図2に示し、比較例1の吸着除去剤を充填したカラムの写真を図3に示す。
産業廃棄物処理場において、ダイオキシン用吸着塔の一つに実施例1のダイオキシン吸着除去剤を20トン充填し、この吸着塔に廃棄物の処理中に発生したガスをSV1500/時間で20ヶ月間通気させた。このときの入ガスと出ガスのダイオキシン濃度を経過時間ごとにそれぞれ測定し、これらの結果を図4に示す。図4中、横軸は、通気時間(月数)を示し、縦軸は、ダイオキシン濃度(ng−TEQ/m3N)を示す。
Claims (3)
- 廃棄物の処理中に発生したガスを通気させて、該ガス中に含まれるダイオキシンを吸着除去するためのダイオキシン吸着除去剤であって、軽油が添着された活性炭を含むことを特徴とするダイオキシン吸着除去剤。
- 前記軽油は、前記活性炭質量の0.1〜30質量%の割合で添着されていることを特徴とする請求項1記載のダイオキシン吸着除去剤。
- 活性炭を回転状態にし、これに軽油を噴霧して添着することにより得られる請求項1記載のダイオキシン吸着除去剤。
