抄録/ポイント： 熱分解液体中の成分の複雑性は,その下流利用の重大な問題を引き起こす。熱分解液体の付加価値と商業化を増加させるために,逐次多段pH調整と有機溶媒抽出法を組み合わせて,粗熱分解液体の化学成分を分離する新しい方法を開発した。粗熱分解液体の化学組成をFourier変換赤外分光法とガスクロマトグラフィー-質量分析によって決定した。結果は,酸(17.54%)とフェノール類(57.44%)が主成分であることを示した。中性化合物(例えばケトン)(38.57%)はpH14で濃縮した。メトキシフェノール(例えば,2,6-ジメトキシフェノール)をpH11で分離し,63.4%を占めた。フェノールとマルトールは主にpH9と7で見出され,相対含有量はそれぞれ11.30%と10.09%であった。pH6および4において,酢酸は最も豊富な化合物であり,それぞれ17.23%および20.72%の含有量であった。pH2の主な化合物は2-メチル-プロパン酸無水物(35.05%)であった。主成分分析(PCA)の結果は,PC1とPC2成分が化学分散のそれぞれ38.8%と26.2%を説明したことを示した。DPPHフリーラジカル捕捉率はフェノール成分と正の相関を示し,酸成分と負に相関した。最も高いDPPHフリーラジカル捕捉活性(88%)がpH11で得られた。本研究は,熱分解液体中の標的成分の分離の理論的参照を提供した。Copyright 2022 Elsevier B.V., Amsterdam.
