\begin{abstract}
The effects of particle concentration and size on hydrodynamics and mass
transport in a slurry bubble column were experimentally studied. With
increasing particle concentration, the averaged gas holdup, gas holdup
of small bubbles and gas-liquid volumetric mass transfer coefficient
decreased, while the gas holdup of large bubbles increased slightly.
With increasing particle size, the averaged gas holdup and kla remained
unchanged when the particle size increased from 55 to 92 ?m, but
decreased significantly when the particle size was further increased to
206 ?m. A liquid turbulence attenuation model which could quantitatively
describe the effects of particle concentration and size was first
proposed. Semi-empirical correlations were obtained based on extensive
experimental data in a wide range of operating conditions and corrected
liquid properties. The gas holdup and mass transfer coefficient
calculated by the correlations agreed with the experimental data from
both two-phase and three-phase bubble columns%
