摘要：

A model is developed for a fluidized bed reactor with the dense phase region treated by conventional two‐phase models. Conversion in the freeboard is obtained based on particle trajectories predicted from drag considerations. The model is applied to an industrial‐scale catalytic cracking regenerator. It is shown that the freeboard region can have an important influence on the overall conversion in the unit. Copyright © 1979 American Institute of Chemical Engineers
