Abstract:
The effect of various parameters on the catalytic oxidation of 1,2-dichlorobenzene (1,2-DCBz) present in simulated flue gas was investigated. A commercial V2O5-WO3/nano-TiO2 catalyst was used and characterized by X-ray diffraction (XRD), N2-physisorption and energy dispersive spectrometer (EDS). The 1,2-DCBz conversion efficiency was increased significantly with higher temperature and lower gas hourly space velocity (GHSV). Different influence levels of HCl on catalytic oxidation were found at lower and higher GHSV. The influence of HCl is irreversible due to the formation of volatile metal oxidochlorides, resulting in a decrease of the number of active sites.
