This research focused on the destruction of naphthalene, representing Polycyclic Aromatic Hydrocarbons (PAHs), using supercritical water (SCW). Experiments were conducted in a Diamond Anvil Cell (DAC) and a batch reactor. The results show that naphthalene can be completely dissolved in supercritical water at 424°C, following the formation of a homogeneous phase. Oxidation of naphthalene takes place in three stages, accompanied by the formation of complex intermediates. Heavier compounds, such as dibenzofuran, fluorenone, and xanthone, are produced during oxidation. All intermediates and naphthalene are oxidized to CO₂ and H₂O during ~1800 s reaction time. The partial reaction pathways are identified.
