Abstract
The gas-liquid mass transfer behavior of syngas components, H-2 and CO, has been studied in a three-phase bubble column reactor at industrial conditio ns. The influences of the main operating conditions, such as temperature, p ressure, superficial gas velocity and solid concentration, have been studie d systematically. The volumetric liquid-side mass transfer coefficient k(L) a is obtained by measuring the dissolution rate of H-2 and CO. The gas hold up and the bubble size distribution in the reactor are measured by an optic al fiber technique, the specific gas-liquid interfacial area a and the liqu id-side mass transfer coefficient k(L) are calculated based on the experime ntal measurements. Empirical correlations are proposed to predict k(L) and a values for H-2 and CO in liquid paraffin/solid particles slurry bubble co lumn reactors.
