摘要：

The gas-solid two-phase flow and the catalytic cracking reaction process in the catalytic cracking riser reactor was studied by Euler-Euler method, and a 12-lumped reaction kinetic model was used to represent the catalytic cracking reaction network and catalyst deactivation was described by the mass ratio of coke to catalyst. The product distribution in the axial and radial direction and the influence of catalyst-to-oil ratio (CTO), asphaltene content and steam flow rate in the feedstock on products were studied. The results show that catalysts and products were enriched near the wall; the proportion of diesel oil decrease and the proportion of olefin increase with the increase of CTO; the proportion of olefins decreased slightly with the increase of asphaltene in feedstock; the higher the amount of inlet steam, the lower the output of olefins. © 2021, Editorial Board of "Journal of Chemical Engineering of Chinese Universities".
