| 英文摘要 | Feedstock injection zone is one of the most key sections for fluid catalytic cracking (FCC) riser reactor. In this article, a 3-D computational fluid dynamics simulation on gas-solid two-phase flow and mixing in this zone was carried out by combining the twofluid model with the energy-minimization multi-scale drag model. The results show that the gas-solid two-phase mixing and flow in the feedstock injection zone can be depicted well by comparing the simulation result with the experimental data. When the traditional feedstock injection zone is used wherein the feed jets spouting upwards into the riser, it is difficult to reach a sufficient mixing; the serious back-mixing of clusters may cause coke because of the effect of secondary flow of feed jet near the riser wall. Finally, a novel scheme that the feed jets spraying downwards into the riser is proposed for realizing sufficient and uniform mixing in the feedstock injection zone. |
