Oxidation of Garbage in Supercritical Water

open access: yesJournal of the Japan Society of Waste Management Experts, 1999
生ごみを構成する食物の湿式酸化分解性および反応パラメータ (反応時間・温度, 供給酸素量および水充填率等) の影響について知見を得ることを目的とし, 22種類の試料について, バッチ式小型反応容器を用い, 超臨界水湿式酸化分解実験を行った。植物性生ごみは酸化されやすく, 種類による酸化分解のしやすさの相違はほとんどみられなかった。動物性生ごみ (魚を含む) も酸化分解されるが, 植物性生ごみに比べると難分解である。種類による酸化分解のしやすさにも大きな相違はないが, 動物性油脂類は肉類 (魚を含む) より分解率が低く, 中でも牛脂は最も酸化分解されにくい。また, すべての試料について酢酸が最後まで残存する有機物であることが明らかとなった。反応パラメータについて, 反応時間10分で分解率が99 ...

Reactions of Supercritical Water and Supercritical Methanol with Benzaldehyde.

open access: yesJournal of The Japan Petroleum Institute, 1996
超臨界水および超臨界メタノールとベンズアルデヒドの反応実験を553Kから693Kの温度範囲で行い, 得られた反応生成物の収率の経時変化より反応経路を推定した。超臨界水とベンズアルデヒドの反応ではベンゼンが主生成物であり, これはベンズアルデヒドの熱分解によって生成したものと思われる。また, 副生成物としては安息香酸とベンジルアルコールが検出された。これらの副生成物はベンズアルデヒドと水との反応によって生成した水和物とベンズアルデヒドとの Cannizzaro タイプの不均化反応によって生成すると考えられる。また, 超臨界メタノールとベンズアルデヒドとの反応では, 主生成物はベンジルアルコールであり, 副生成物としてジメチルアセタール, ベンゼン, 安息香酸メチルが得られた ...
