摘　　要：在一套７１０／４０００×８７０／１１０００ｍｍ大型有机玻璃流化床中，测定了大比重的ＦＣＣ催化剂在湍流流化床密相密度沿径向的分布规律。试验结果表明，湍流流化床密相区密度沿径向有一个明显的分布。采用多项式模型对试验数据进行了关联。The radial density distribution of FCC catalyst in the dense phase of the turbulent regime has been studied in a large size fluidized bed made of plexiglass with dimensions of φ710/4000×φ870/11000 mm.It is shown that the dense density of turbulent fluidized beds along bed radius has an obvious distribution.The radial distribution of voidage in the dense phase of the turbulent fluidized beds can be described by a polynomial model.
