✦ Synopsis

Concentration profiles within a fluidized bed have been measured using a hydrocarbon analyzer and have been utilized to establish from them mass transfer coefficients and the correspondingj,-factor relationship, s,J, = 0*947/Re I'*, for 100 < Re < 450. The experimental approach involved the evaporation of n-decane from the surface of Celite particles, ranging from 0.1215 to O-0721 in. dia. In addition, a model is presented which is based on the variation with bed height of a*, the interfacial area. This model predicts concentration profiles and actual mass transfer coefficients for a fluidized bed system.
