Popis: Experiments were carried out to determine the liquid side mass transfer coefficient in spout-fluid beds of ion exchange resin. The ratio (Sh S—F ) overall /Sh fluidized is correlated with the ratio of the flow rate through the nozzle to the total flow rate for different experimental conditions. A method for the calculation of the initial conversion in a spout—fluid bed is given and a model of a spout—fluid bed ion exchanger involving liquid flow pattern is proposed. Particle motion in the annulus was measured. The model is based on the assumption of film diffusion control. Experimental results obtained in the study of the conversion of ion exchange resin “Amberlite IR-120” in Na + form and diluted hydrochloric acid in a spout—fluid bed are in agreement with theoretical predictions.
