The authors discuss the axial solids concentration distribution in slurry bubble columns containing monodispersed and binary mixtures of solid particles studied for both batch and continuous operation. Air and water were used as the gas and liquid phases; respectively. The gas velocity ranged from 0.016 to 0.173 m/s and the slurry velocity ranged from 0.0 to 3.07cm/s. Glass beads were used as the solid phase. The effects of gas velocity, slurry velocity and particle size on the axial solids concentration distribution in the column were examined. A mechanistic model is developed to describe the solids concentration distribution in the column containing monodispersed solid particles; the model predicts the experimental data very well for both batch and continuous operation.
