摘要

Disappearance kinetics of 2,4-dichlorophenol (DCP) oxidation in supercritical water was investigated. The experimental data reveal that the reaction is 0.97 order for DCP and 1.16 order for oxygen. The activation energy and the Arrhenius pre-exponential constant are 13.6 kcal/mol and 72.9 M-1 13s-1, respectively. Several condensation by-products, such as trichlorophenols and dibenzo-p-dioxin, from supercritical water oxidation (SCWO) of DCP at 673 K were determined. We also found experimentally that the presence of sodium or iron cations in oxidation of DCP in supercritical water suppressed the formation rate of condensation by-products and enhanced the reaction conversion.
