Abstract
A numerical analysis was carried out to investigate the degradation of Volatile Organic Compounds (VOC) in photocatalytic microreactors with different inner geometries. Two different cases of microreactor were considered, namely, one microreactor has bump on the channel and the other has no bump on the channel. The removal efficiency of VOC has been calculated by the Langmuir-Hinshelwood reaction rate equation that was obtained from the experimental results. From the numerical calculations, it was observed that the conversion ratio of VOC for the microchannel with bump is about 4.5% greater than the microchannel without bump. And the mass transfer characteristics in the microreactor are also shown in numerical results. These results can be used effectively for the photocatalytic numerical analysis.
