Analysis of cross-flow jet-type singlet oxygen generator

摘要

A cross-flow jet-type singlet oxygen generator has been developed, tested and analyzed in order to characterize the dependence of output performance on major input parameters. A thermal-balance model, which can predict O2(1Δ) yield, gas temperature, and gas residence time, is proposed, and the resultant theoretical results are compared to the experimental data. Combined with computational fluid dynamics-based gas residence-time analysis, the model provides good agreement with the measured value of the O2(1Δ) yield and the gas temperature. The surface chemistry model was applied to the measured Cl2 utilization data, and was found to be inconsistent in the regime of high Cl2 loading on the basic hydrogen peroxide jet, indicating that depletion of HO2- is taking place.
