在小型固定床装置上,采用工业双金属催化剂Pt-Re/γ-Al_2O_3,针对芳烃型重整装置的实际需求与催化重整反应机理,采用五集总动力学模型对煤基石脑油催化重整进行了研究。运用四阶Runge-Kutta法与最优化求解中的变尺度法(B-F-G-S)求解动力学模型,并对模型进行了验证。通过实验验证,重整产物的模型预测值与实际值相对误差均小于4%,表明该动力学模型对煤基石脑油催化重整的产物分布具有较好的预测能力,为煤基石脑油重整工艺的进一步优化提供了依据。
In a small fixed-bed unit, an industrial bimetallic catalyst, Pt-Re / γ-Al 2 O 3, was used. According to the actual demand of the aromatic reformer and the catalytic reforming reaction mechanism, a five-lump kinetic model The whole study. The fourth-order Runge-Kutta method and the variable-scale method (B-F-G-S) were used to solve the dynamic model and the model was verified. The experimental results show that the relative errors between predicted and actual values of the reformate are less than 4%, indicating that the kinetic model has a good predictive ability for the product distribution of coal-based naphtha reforming. The entire process to provide a basis for further optimization.
