This study has been numerically conducted to investigate the removal efficiency of Volatile Organic Compound (VOC) in photocatalytic micro-reactor. This study has placed emphasis on the improvements of the working condition of photocatalytic micro-reactor. The micro-reactor consists of 19 microchannels with a rectangular cross-section. For the validation of the current numerical study, a computation has been carried out to simulate an existing experimental study on the cylindrical reactor, which has shown a good agreement. The degradation characteristics with different inlet concentrations and velocities have been obtained. The current results can be used for the design of advanced photocatalytic micro-reactor.
광촉매 마이크로 반응기의 내부 형상에 따른 VOC 분해특성에 관한 수치해석적 연구
용정권(Jung Kwon Yong),김창녕(Chang Nyung Kim),염민규(Min-Qou Youm) 대한기계학회 2007 대한기계학회 춘추학술대회 Vol.2007 No.5
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.
