Influences of suspended fine particles on gas holdup and mass transfer characteristics in a slurry bubble column

In this work, slurries with suspended fine particles (whose size is smaller than 10 ..mu..m) of lower than 1 wt. % were used to provide an insight into the solid-bubble interaction in a bubble column. The liquid property and the gas sparging system as well as the particle size were varied; the effects of these variables on the gas holdup and the volumetric liquid-side mass transfer coefficient were determined experimentally and are here discussed quantitatively.
