Abstract

An experimental investigation has been conducted on the direct establishment of mass transfer driving forces for the vaporization of n‐decane from Celite particles fluidized by air. Ranges of particle sizes and reactor diameters were employed.

Concentration profiles of n‐decane were determined and were integrated to obtain the actual average concentration difference for the entire bed. The ratio of the actual driving force to the corresponding log‐mean value has been correlated with the average particle size, the fluidized bed height, and the modified Reynolds number to produce two relationships capable of predicting these ratios to within 2.5% (83 runs). The results for these mass transfer studies should also be applicable to comparable studies on heat transfer in fluidized beds.
