针对ＵＯ＿３的Ｎ＿２还原反应建立了多孔挡板流化床反应器模型。将多孔挡板床的每一级视为具有相似的流动状态，每一级的上、下段称为稀、密相段，分别用鼓泡床和活塞流模型描述。该模型的计算值与￠６３ｍｍ的多孔挡板床Ｈ＿２还原ＵＯ＿３的热态实验值能较好的吻合。还预计了还原温度、操作气速和挡板结构参数对固相转化率的影响，为该类反应器的工业设计、放大和优化提供了依据。
A porous baffled fluidized bed reactor model was established for the reduction of U_2 by UO_3. Each stage of the porous baffle bed is considered to have a similar flow regime, the upper and lower sections of each stage being referred to as dilute, dense phase sections, described by a bubbling bed and plug flow model, respectively. The calculated value of this model is in good agreement with the experimental results of the thermal state of UO_3, a porous baffle bed H_2 of ¢ 63mm. The effects of reduction temperature, operating gas velocity and baffle structure parameters on solid phase conversion were also predicted, which provided the basis for industrial design, amplification and optimization of such reactors.
