Sažetak
The sorption of copper ions on zeolite NaX is a heterogeneous process, and as such dependent on hydrodynamics in a batch reactor. Therefore, this work aimed to study the effect of mixing speed (N/NJS ratio values, i.e. impeller speed/minimum impeller speed for complete suspension) on the kinetics and power consumption of the process examined.The experiments were carried out in a glass batch reactor of nonstandard configuration (D/dT=0.6, C/H=0.1), equipped with baffles and the SBT impeller. A transient multiphase computational fluid dynamics model was developed to gain valuable insight into complex flow kinetics. The Blanchard model, Mixed surface reaction and diffusion-controlled sorption kinetic model, and Weber-Morris model were used for the kinetic analysis of the experimental kinetic data.According to and RMSE values, the reaction is kinetic controlled in all experiments performed.
