Decomposition of Chlorinated Volatile Organic Compound by Metal Catalytic Incineration

摘要

In this study, the oxy-DE chlorination of 1, 2-dichloroethane with excess oxygen fuels was performed in laboratory scale tubular reactor with packed Pt and Fe2O3 catalyst. It is important to understand the influence of operation parameters, such as catalysts, temperature, and retention time on removal efficiency. The catalysts, including noble metal catalyst (Pt) and metal support catalyst (Fe2O3), were used in this experiment. Additionally, the temperature and retention time were operated from 450°C to 650°C and from 0.3 to 1.5 s, respectively. Reactants and products were analyzed quantitatively by gas chromatography with a flame ionization detector (GC/FID) and Mass Spectrometer (GC-MS). In order to evaluate the oxidation kinetic behavior of 1, 2-dichloroethane with Pt and Fe2O3 catalyst, the Arrhenius equation was used in this study. The experimental data were compared with those predicted results from the kinetic model. The results showed that the removal efficiency was relative to intermediate, final product profiles, retention time, and temperature. Furthermore, the optimum operation conditions of the reactor with Pt catalyst and Fe2O3 catalyst were determined.
