The axial sold concentration distribution in a slurry bubbly column was studied in 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 0.031 m/s. Glass beads of diameters 163,97, and 49 {mu}m were used as the solid phase. The holdup distribution of each solid in binary mixtures was also studied. The effects of gas velocity, slurry velocity, and particle size on the axial solid concentration distribution were examined. A mechanistic model is developed to describe the solid distribution in the slurry bubble columns. The model accounts for the solid distribution for both batch and continuous operation involving monodispersed and binary mixtures of solid particles.
