Abstract
The gas-liquid mass transfer performances of a novel three-phase react or involving both airlift and mechanical stirring have been tested usi ng aqueous solutions of glucose. Stirring in addition to classical air lift leads to an importance increase of k(L)a. The absolute increase d epends mainly on the stirrer speed are not on the gas velocity. A slig ht effect of the solid loading with a maximum at about 2% (w/v) was ob served. Two correlations that show the influence of physical parameter s are proposed for both water and glucose solutions. (C) 1998 SCI.
