在汽油催化转化反应动力学模型和气-固两相流模型的基础上,将流动、传热、反应综合考虑,建立了催化裂化汽油催化转化提升管反应器的反应-流动耦合模型。模拟结果与中型实验提升管出口数据吻合较好。数值模拟了提升管反应器内气相组成、温度分布、速度分布沿提升管高度变化,以及提升管出口产品产率随温度和剂油比的变化情况,模拟结果反应了其变化规律,验证了模型的可靠性。
Based on the catalytic kinetic model of gasoline and the gas-solid two-phase flow model, the reaction-flow coupling model of catalytic riser catalytic riser riser reactor was established considering the flow, heat transfer and reaction. The simulation results are in good agreement with the export data of medium-sized riser. The gas composition, temperature distribution and velocity distribution along the height of the riser were numerically simulated. The changes of the product yield at the outlet of the riser with the temperature and the ratio of oil to solvent were simulated. The results showed that the model The reliability.
