EFFECT OF BUBBLE COALESCENCE ON PERFORMANCE OF FLUIDIZED BED REACTORS. Conference Paper

abstract

• The effect of bubble growth by coalescence on predictions of reactant conversion in a fluidized bed catalytic reactor has been investigated for reactions that are described by either Langmuir-Hinshelwood or a simple first order kinetics. The two-phase model of Davidson and Harrison with continuous change of bubble size with height has been employed in all calculations. The results of these calculations have been compared with those of models using a constant bubble diameter. These effective bubble diameters have been determined in three ways: by calculating an integral average bubble diameter, by calculating the bubble diameter which gives the same bed expansion, and by calculating the bubble diameter which gives the same total number of mass transfer units.
