Kinetic modeling of homogeneous low-temperature multi-pollutant oxidation by ozone

摘要

The features of the low-temperature (300-600 K) oxidation process by ozone are examined. The process is modeled employing "full'' chemistry and simulated in a perfectly stirred reactor (PSR). The issues addressed include the rate of multi-pollutant of flue gas removed by the process, the critical temperature window, the range of ozone demand (if any) for high multi-pollutant removal and the impact of other species and residence time on multi-pollutant removal. The results are discussed in comparison with earlier experimental findings. For the simulated flue gas stream, the optimum temperature and ozone concentration required for high multi-pollutant removal are 400 +/- 20 K, 600-800 ppm, respectively.
