Gas-liquid mass transfer in a slurry bubble column reactor under high temperature and high pressure

The gas-liquid mass transfer of H-2 and CO in a high temperature and high-p ressure three-phase slurry bubble column reactor is studied. The gas-liquid volumetric mass transfer coefficients k(L)a are obtained by measuring the dissolution rate of H-2 and CO. The influences of the main operation condit ions, such as temperature, pressure, superficial gas velocity and solid con centration, are studied systematically. Two empirical correlations are prop osed to predict k(L)a values for H-2 and CO in liquid paraffin/solid partic les slurry bubble column reactors.
