According to the results of experiments,a mathematial model for the regener- ator with the consideration of the effect of dilute phase has been proposed. Based on industrial data,the model parameters have been estimated and their stable values were obtained.

本文的目的是将流态化理论应用于细粉催化剂流化催化裂化再生器数学模型之中。借助于光导纡维测试技术研究了在再生催化剂流化床中颗粒流动速度及其径向分布规律和气泡频率及其径向分布规律。实验所用装置为φ300×11400三维冷模流化床,介质为空气和工业再生催化剂,根据实验结果提出了一个流化催化裂化再生器数学模型。在模型中考虑了稀相的影响,并采用工业数据对所提出的模型进行了模型参数估值,得到了比较稳定的模型参数值。

A study of fluidization experiment for commercial regenerated catalyst

在塔内径d为0.294m、高h为11.4m的有机玻璃塔中,以冷空气为介质,对工业的催化裂化再生催化剂进行了流态化实验研究。其条件是:催化剂固定床高H0与塔内径之比(H。/d)分别为1.5、2.0、2.5、3.0、3.5、4.0;空塔气速U_f在0.1~1.0m/s范围内。根据测得的塔内轴向各相邻点之间的压差,计算床层各段的平均密度,探讨了流化床中催化剂密度沿床高的分布规律和密相密度随气速的分布规律,得出了有关的分布图和关联式。
