Abstract

This study analyzed the mechanism of photocatalytic reaction and described the toluene removal process through the equation of L-H reaction rate. Experiments were conducted by using the designed photocatalytic reactor to measure UV radiation, differential pressure in filter and the toluene removal efficiency as a function of air humidity, air velocity, toluene concentration of the reactor entrance and UV radiation. The computational analysis was performed to simulate the UV radiation on the filter surface, the flow field in the reactor and the toluene removal. As a result of the experiments, it was confirmed that the humidity had a large effect on the photocatalytic reaction efficiency. While the amount of the toluene removal increased, the toluene removal efficiency decreased in case of increasing the toluene concentration of the reactor entrance. The maximum and minimum toluene removal efficiency was at 28% and 3.1%, respectively. As a result of computational analysis, the uniformity of UV radiation on the filter surface was at 87%, and it was confirmed that the air flow in the reactor was uniform, and the L-H reaction model was considered as appropriate model for the photocatalytic reaction in this study.
