Abstract: Activated carbons were produced from five kinds of waste phenol-formaldehyde (PF) resins by the steam activation. The specific surface area of an activated carbon made from a most commonly used PF resin (sample A) reached more than 1000m2/g in about 25% yield. The amounts of benzene and methanol vapors adsorbed on the activated carbon were much larger than those adsorbed on a commercial carbon (Figs. 8,9). The amount of phenol adsorbed from the dilute aqueous solution on the activated carbon was comparable to that of another commercial carbon (Fig. 10). The specific surface areas of activated carbons produced from other two PF resins (sample B and C) were also comparable to those of an activated carbon produced from the Miike coal (Fig. 6). The activated carbon made from sample A was rendered to the repeated cycles consisting of adsorption of waste water and thermal regeneration. Although the specific surface area and the adsorption capacity of the activated carbon decreased with an increase of the number of the cycle, the extents of the decrease were similar to those of a commercial carbon (CAL). Thus it was found that the activated carbons made from waste PF resins serve for practical use
5種類のフェノール樹脂廃棄物と1種類の純粋フェノール樹脂から水蒸気賦活法によって活性炭を製造し,賦活にともなう比表面積,吸着性能の変化を詳細に検討した。もっとも一般的なフェノール樹脂の廃棄物(試料A)から原料基準で0.25以上の高収率で1000m2/gの比表面積を有する活性炭が得られた。この活性炭のベンゼンならびにメタノール蒸気の吸着量は市販やし殻活性炭のそれらを上回った。さらに,ヨウ素吸着量も市販の活性炭(CAL)を上回った。以上の結果,試料Aから製造した活性炭は気相吸着用,あるいは液相での低分子物質吸着用に適すると考えられた。また,試料B,Cからも三池炭を原料とした場合と同程度の比表面積を有する活性炭が得られた。 つぎに,試料Aから製造した活性炭について合成廃水の吸着と加熱再生からなるサイクルを5回くり返し,一連の操作にともなう比表面積,細孔径分布,吸着性能の変化などを検討し,その結果をCAL炭に対する同様の実験結果と比較した。両活性炭の再生特性には大差がみられず,フェノール樹脂廃棄物から製造した活性炭がくり返し再生利用の可能性においても市販品に匹敵することが明らかになった。
