Abstract
The chapter presents the results of experimental and numerical studies of the impact of the design of selected zones of a hybrid fluidized-bed apparatus on its hydrodynamic properties. In particular experimental tests were carried out to characterize the hydrodynamics of the bottom zone and of the degassing zone. The analysis of liquid flow through these zones was performed using tracer experiments done with the stimulus-response method to determine the presence of local liquid circulation that could lead to local oxygen deficiency in the apparatus (dead zones) or privileged flow channels. In addition, CFD simulations of the liquid flow through the bottom zone of the apparatus were carried out assuming different design solutions for this zone.
