Experiments of the toluene decomposition in real air flow by synergic effect of discharge plasma with nano-TiO2 catalyst are conducted utilizing a self-developed air-steam wire-cylinder reactor under atmosphere pressure and room temperature.The results show that the distribution of flow field in reactor affects decomposition efficiency of toluene dramatically

the combinations between different electric field and flow field cause different decomposition effect.Positive pulse benefits the decomposition and creates a 47.07% higher decomposition effect than that of negative one does at the discharge voltage of 33 kV.The synergic effect of discharge plasma with nano-TiO2 catalyst significantly enhances the decomposition capability of reactor

and the decomposition efficiency approaches to 94.74% when the initial concentration of toluene is 400 μL/L.The decomposition efficiency increases with the increasing discharge voltage and approaches to 94.63% when the discharge voltage is 45 kV and the initial concentration of toluene is 335 μL/L.Larger capacitance discharge enhances toluene decomposition and the enhancement improves with the increase in voltage.
