摘　　要：在一套 Φ1 2 0 0 mm× 1 2 0 0 0 mm/Φ1 0 0 0 mm× 5 0 0 0 mm的大型有机玻璃流化床中考察了 FCC催化剂在稀相区夹带粒度分布的情况 ,得出夹带颗粒与稀相高度及表观气速的分布规律 ,即随着高度的上升 ,小颗粒所占分率逐渐增多 ,大颗粒所占分率逐渐减小。通过对实验结果的分析 。The rule of the distributor of entrainment particles in the dilute phase of turbulent fluidized bed has been studied in Φ1 200×12 000/Φ1 000×5 000 large FCC regenerator.According to the analysis of the experimental results,the entrainment model of particles has been established,and with the raised height,the small particles are increased,while the large particles are reduced.
