Decomposition of Chlorinated Volatile Organic Compound by Metal Catalytic Incineration

Abstract

Abstract-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 Fe 2 O 3 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 (Fe 2 O 3 ), 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 . On the other hand, base metal oxides are much less expensive and allow higher catalyst loading. Higher catalyst loading will bring to higher active surface area in metal oxide [19]. Although very active, the application of catalyst is using to low operating temperatures because of volatile formation and toxic chromium oxy-chloride. [1].This study we also notice that function of the oxy-dechlorination of 1, 2-dichloroethane with excessive oxygen was carried out during laboratory scale tubular reactor with packed Pt and Fe 2 O 3 catalyst. Spivey [3] indicated that those major parameters affecting catalytic incineration of VOCs included catalyst type, VOC speciation, VOCs concentration, operating temperature, space velocity and O 2 concentration. In order to understand importance and influence of operating parameters on degradation of 1, 2-dichloroethane, the catalyst characteristics were examined first. Related kinetic equations were also established based on observed experimental results.
