Abstract

Hydrodynamic parameters were evaluated in a laboratory scale apparatus in order to provide data for CFBR (Circulating Fluidized Bed Reactor) design. Pressure drop and hold-up axial profiles were measured in a wide range of conditions with particular emphasis paid to dilute phase conveying where a pseudo-homogeneous flow is established in most of the upper part of the reactor. A safe correlation between pressure drop and solids hold-up is the link which permits a prompt evaluation of the reactor performance after exponential fitting of the pressure gradient along the axial direction. Ozone decomposition was chosen a as tracing reaction; comparison between measured and predicted conversion values was the ultimate goal of the present study aimed at demonstrating a possible approach for reactor design from gross parameter measurements.
