Gas/liquid mass transfer has been studied in air/water fluidized beds of 0.05‐8 mm glass spheres in a 0.14 m diameter reactor. The volumetric mass transfer coefficients k L a were independent of bed height, and, for particle diameters up to 1 mm, decreased linearly with solids concentration. Low solids loadings as well as large diameter particles significantly increased k L and a , respectively, as compared to the two‐phase system.
