Zusammenfassung:The content of 1,2-dichlorobenzene in the air was analyzed. A significant effect of catalysts loading and temperature on 1,2-dichlorobenzene destruction efficiency was observed and no effect of the linear flow velocity through the catalyst on o-dichlorobenzene destruction efficiency was reported. The kinetics of 1,3-dichlorobenzene decomposition was determined, specifying the order of reaction and dependence of the decomposition rate constant on temperature, using a simple power-rate law model. The results indicated that no influence of the linear flow velocity through the catalyst on the obtained 1,2-dichlorobenzene decomposition efficiency was observed. The results concluded that vanadium-tungsten catalyst on a monolithic carrier made from TiO sub(2) gamma -Al sub(2)O sub(3) revealed very good activity, which enabled over 80% efficiency of 1,2-dichlorobenzene destruction at the temperature about 250 degree C with the catalyst load reaching around 8200 h super(-1).
