The hydrodynamic and mass transfer characteristics were measured for various gases (H{sub 2}, CO, N{sub 2} and CH{sub 4}) in a liquid hexane mixture in the presence and absence of actual Fischer-Tropsch catalyst using a 0.3-m diameter, 2.8-m tall slurry bubble column reactor. The reactor was operated in the churn-turbulent regime with superficial gas velocities reaching 0.25 m/s, catalyst concentrations up to 50 wt.% and pressures up to 8 bar. The experimental gas holdup and the mass transfer coefficient values for the four gases were found to increase with the superficial gas velocity and pressure. The values, however, appeared to decrease with increasing catalyst concentration.
