【Abstract】 A mathematical model for the complex reactionA■→B→Ccarried out in a fluidiyed bed reactor was established on the basis of cloud phase flow model which was derived for predicting concentration distribution,conversion,yield and selectivity of the chemical process.One of the advantages of this proposed model is that there are no unknown parameters included in the model. and the calculating program is quite simple.Catalytic oxidation of benzene to maleic anhydride and to carbon oxides was studied and simulated as an example of complex reaction.It was shown from the result of simulation that predictions of the present model agree well with both the laboratorial and pilot experimental data and thus,the present model may provide some useful guidance for the design of fluidized bed reactors of complex reactions.更多还原
