Abstract
【解決手段】 比表面積700〜1,500m2/g,全細孔容積0.3〜0.7cc/g,且つ表面酸性基量が0.5meq/g以下と官能基量が少ない繊維状活性炭を使用した際に、吸着性能が優れることを知見した。さらに、低沸点有機化合物の水蒸気による脱着方法に関し、脱着水蒸気導入バルブの開度と導入時間を可変とし、脱着水蒸気流量を段階的に制御することにより、低沸点有機籠物の脱着を効率よく実施できることを見出した。
【選択図】 なし
Description
である。
繊維状活性炭フェルトを円筒状に巻きつけた吸着エレメントを用い、吸着と水蒸気による脱着を交互に行う排ガス処理装置を用いて、塩化メチレンと塩化ビニルモノマーガスを各々別に吸着処理した。尚、表1には塩化メチレン(MC)と塩化ビニルモノマー(VCM)およびトルエンの組成式、分子量、沸点を示してある。
繊維状活性炭素材約0.1g採取し、120℃で12時間真空乾燥後秤量した。上記サンプルの液体窒素の沸点(−195.8℃)における窒素ガスの吸着量を相対圧が0.0〜0.2の範囲で徐々に高めながら数点測定した。結果をBETプロットし、重量当たりの比表面積を求めた。
相対圧0.95での窒素の吸着量から計算で求めた容積。
JIS−K−1477「5.7トルエン吸着性能」において、トルエン蒸気濃度を飽和濃度の1/10にして求めた値である。
繊維状活性炭素材約0.3gを純水にて洗浄し、熱風乾燥に続き12時間の真空乾燥を施した後、秤量を行った。上記サンプルを、250mlの1/10規定NaOH標準溶液に浸漬した状態で、25℃で10時間振とうした。上記溶液をガラスろ過器でろ過した後、ろ液25mlを正確に分取し、これを1/10規定HCl標準溶液にて滴定した。指示薬は、フェノールナフタレインを使用した。同様の操作を繊維状活性炭素材を入れない状態で行い、これを空試験の滴定量とした。活性炭素材重量当たりの表面全酸性基量は、次式により求めた。
表面全酸性基量=D*f/W[meq/g]
ここでDは空試験の滴定量から繊維状活性炭素材を入れた時の滴定量を差し引いた値[ml]である。fは1/10規定のHCl標準溶液のファクターである。Wは活性炭素材の重量[g]である。
平衡水分率はJIS−Z0701に基づき25℃、相対湿度60%で測定を実施した値を用いた。
