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.
