摘要/Abstract

摘要： 在流动模型和集总反应动力学模型的基础上,将流动、传热、反应综合考虑,建立了渣油催化裂化提升管反应器的数学模型,通过对4套不同工况进行数值模拟,考察了反应器内气相组成分布和催化剂颗粒的温度、速度分布,得到了与工业装置基本一致的提升管出口参数,从而验证了模型的可靠性.

Abstract: A three - dimension gas - particle two - phase flow - reaction model for RFCC riser reactors was developed by using turbulent flow model and lumping kinetics model and integrating flow, heat transfer and reaction. Numerical simulation of four commercial riser reactors was carried out, and the velocity, temperature and concentration profiles in the axial and radial sections were revealed. The calculated parameter values at the outlet of reactor are consistent with the commercial data, which verified the reliability of the flow - reaction model.
