Resumo (PT): A new experimental technique is presented for the measurements of axial dispersion of a liquid in semibatch packed bubble columns. Values of the dispersion coefficient were obtained in a 0.10 m diameter column with five different packing. The liquid used were water and mixtures of glycerine and water with viscosities up to 1.0 Pa s. The data reported show the dispersion coefficient to decrease markedly with decrease in the size of the packing elements and with increase in the liquid viscosity.
