A kinetic study of ethylene oxidation in a well-stirred reactor
Experimental results for the oxidation of ethylene in a well-stirred reactor are examined, and the results are analyzed using a numerical model with a detailed chemical kinetic reaction mechanism. Temperatures studied range from 1003k to 1253K, at atmospheric pressure. Comparisons between computer and experimental results show good agreement at temperatures up to about 1200K. However, at higher temperatures, computer rates of ethylene conversion are much higher than those measured. In the range 1200 - 1250K the model predicts effectively complete consumption of the fuel within the given residence time, while the experiments indicate incomplete consumption. These trends, observed previously for n-pentane oxidation in the same well-stirred reactor, are discussed in terms of turbulent mixing and the effects of fluctuations on the rate of fuel consumption in the reactor. 8 refs., 3 figs., 1 tab.
