✦ Synopsis

Gas holdups and volumetric mass transfer coefficients (kLa) for oxygen were measured in suspensions of kieselguhr (7 pm), aluminium oxide (8 pm) and activated carbon (5 pm) in water or 0.8 molar sodium sulfate solution. By comparison to previously reported specific interfacial areas (a) determined by the sulfite oxidation technique, the liquid side mass transfer coefficients (k ) can be evaluated. Most data are well correlated as a decreasing function of the effective viscosity. However, k. concentrations of solids with a high density. rgher k, values are determined at low INTRODUmION
