Phenol is gasified in supercritical water at 400−500 °C under a pressure of 25 MPa over Ni-Ru bimetallic catalyst. Several liquid products including cyclohexanol, 2-methyl cyclopentanone, toluene, alkylphenol etc. are identified and possible reaction paths among them are proposed. Gaseous products consist of H₂, CH₄ and CO₂. We develop a quantitative kinetic model based on a simplified reaction network in which intermediates are lumped. The model accurately captures the trends of concentration variation for phenol and gaseous products. Steam reforming of phenol to form CO is the main source of H₂ and nearly all CH₄ is formed from methanation of CO under 450 °C. Concentration of H₂ is most sensitive to steam reforming to form CO₂ while steam reforming to form CO strongly affects CH₄ production at 450 °C. The model has predictive capacity when varying initial phenol loading while it lose some accuracy for a higher water density condition.

在Ni-Ru双金属催化剂上，苯酚在400-500°C的超临界水中在25 MPa的压力下气化。鉴定了几种液体产物，包括环己醇，2-甲基环戊酮，甲苯，烷基酚等，并提出了其中可能的反应途径。气态产物由H ₂，CH ₄和CO _2组成。我们基于简化的反应网络建立了定量动力学模型，在该网络中，中间体被集总。该模型准确地捕获了苯酚和气态产物的浓度变化趋势。苯酚的蒸汽重整形成CO是H ₂的主要来源，几乎所有的CH ₄都是在450°C下由CO甲烷化而形成的。H ₂浓度对蒸汽重整形成CO ₂最为敏感，而蒸汽重整形成CO对450°C的CH ₄生成有很大影响。当改变初始酚含量时，该模型具有预测能力，而对于较高的水密度条件，该模型会失去一些准确性。
