作者首先在对反应器进行特征分析的基础上，建立了描述中试规模多级外循环流化床生物反应器流动特性的串级全混流模型，并对理论模型进行了模拟计算分析和讨论，在此基础上，作者分别在无循环和有循环(改变示踪剂用量、流加流量和循环流量)的条件下，利用脉冲示踪法对一到五级串联外循环流化床反应器进行了停留时间分布实验，结果表明，在循环流量与流加流量的比值达到大于等于4时，中试规模多级外循环流化床反应器的流动特性接近串级全混流模型，通过数据回归拟合的方法，建立了中试规模一到五级串联外循环流化床反应器的流动模型。 - The study on flow properties of multistage fluidized - bed bioreactor with external circulation at a pilot scale will offer instructions of theoretical parameters in actual fermentation , and it can also provide very important theoretical basis in the course of engineering amplification for future commercial process

多级外循环流化床生物反应器作为一种新型生物反应器，由于具有转化率高、反应彻底、对颗粒损伤少等优点在固定化细胞制取燃料酒精技术上得到应用。但是，国内关于中试规模多级外循环流化床反应器流动特性的研究还很少，而流动特性是反应器物理传递过程的基础，是研究物料在反应器中转化率高低的重要因素，因此，弄清楚外循环流化床反应器的流动特性是非常重要的。
