摘要
基于反应动力学实验结果，分析考察了丙烯氨氧化反应的动力学行为，提出了关于反应转化率与目的产物收率的幂函数形式的拟合模型，藉此对某厂丙烯腈工业流化床反应器的操作数据进行了关联，在考虑反应器中气－固流动影响的前提下，建立了丙烯腈反应器的下述宏观数学模型：反应转化率Ｘ＝０．８３２５ｕ－０．１０５８Ｒ－０．０１６４ＮＨ３Ｒ０．２５０９Ｏ２ｅｘｐ（－０．７４５９＋３５９．７９／Ｔ）丙烯腈单收ＹＡＮ＝０．０８９６ｕ０．０３４２Ｒ０．２３３３ＮＨ３（５．８２４５ｅｘｐＲ１．１３３７Ｏ２－Ｒ４．７４４５Ｏ２）ｅｘｐ（－２．０６５１＋５２２．９８／Ｔ）模型拟合的相对误差小于１０％．
The kinetic behavior of the ammoxidation reaction of propylene was experimentally investigated and a mathematical model of reaction conversion rate and yield with power function is proposed Using operating data from an industrial reactor and considering the effect of gas-solid flow in the reactor, the Marquardt method for nonlinear regression was used for creating the following macroscopic mathematical model of a fluidized-bed reactor for synthesizing acrylonitrile Reaction conversion X=0 8325u -0 1058 R -0 0164 NH 3 R 0 2509 O 2 exp (-0 7459+359 79/T) Yield of acrylonitrile Y AN =0 0896u 0 0342 R NH 3 0 2333 (5 8245 exp R O 2 1 1337 -R O 2 4 7445 ) exp (-2 0651+522 98/T) The model fits experimental data quite well with relative error below10 %
