摘要
在Φ８７０／Φ７１０和Φ１２００／Φ１０００、扩径段高度１５０００ｍｍ，扩径段下部高度４５００ｍｍ的工业规模流化床内，用两种ＦＣＣ催化剂，进行了夹带分离高度ＴＤＨ和颗粒密度及夹带颗粒粒径分布的研究，在实验数据基础上，进行数值计算及回归，得出ＴＤＨ准数关联式和粒径分布轴向分布式．与他人的研究结果比较，本研究结果更接近生产规模的工业实际．
The TDH(transport disengaging height),the particle density and the particle size distribution of two kinds of FCC (fluidized catalytic cracking) catalysts were investigated in two large size fluidized beds with dimension of Φ 870/Φ710 ×15000/ 4500 and Φ1200/Φ1000 ×15000/4500 mm respectively. Based on the experimental data, the correlation of the TDH and the axial distribution of particle size were obtained. Compared to the other correlations reported in the literature, the present correlation is better agreeable to the real situation of large size bed in production scale.
