摘要
提出一个包含十四集总组分、25个反应的催化重整动力学模型,以较少的集总和较高的预测精度适应实际催化重整生产的需要;根据在催化重整微型反应实验装置上获得的实验数据,得到重整反应动力学模型的参数;用该模型预测产物组成和催化重整装置的模拟。结果表明:预测的最大绝对偏差为2.30%,偏差大部分小于2.0%;模拟得到产物中各组分及温度在反应器中分布与催化重整反应机理吻合;模型集总划分适中,使用方便,能够用于催化重整装置的预测。
A catalytic reforming kinetic model containing 14 lumped components and twenty-five reactions was proposed, which has a moderate number of lumps and higher prediction accuracy to meet the needs of the production of catalytic reforming. On the basis of the experimental data from a micro reactor in the laboratory, the parameters of the catalytic reforming kinetic model were determined. The model was used to predict the composition of the product and to simulate an actual cata-lytic reforming unit. The results show that the maximum absolute deviation is 2. 30%, in which most deviations are less than 2. 0%. The product composition and the temperature distribution in an actual reactor are obtained based on the model, which is in agreement with the catalytic reforming reaction mechanism. The established model has appropriate lumps and can be conveniently used for the prediction of catalytic reforming unit.
