The effects of column dimensions, gas velocity and properties of the liquid and the solid particles on the gas holdup εG and the volumetric liquid-phase mass transfer coefficient kLa in a solid suspended bubble column with a draught tube and a conical bottom were studied experimentally in a liquid-solid batch operation. The presence of suspended solid particles in the column reduces the values of εG and kLa, and their reduction due to the addition of solid particles to the column increases with increasing solid concentration and terminal velocity of a single particle. Based on these observations, empirical equations for εG and kLa are proposed which are applicable to columns with diameter of 0.1-0.3 m.
