Abstract
The data of Yamazaki and Miyauchi9) for heat transfer between emulsion phase and gas bubbles in fluid-bed catalytic contactors are analyzed in terms of the Bubbling Bed Model of Kunii and Levenspiel5). It is shown that the effective bubble size needed to fit the Bubbling Bed Model to the reported transport rates is much smaller than the actual bubble size; however, more realistic assumptions regarding temperature measurements indicate that their reported transport rates are much too high. Temperature-corrected data are shown to be reasonably estimated by the Bubbling Bed Model using the measured bubble size.
