Experiments of pressure effects on gas holdup and bubble size in slurry bubble columns at 5.6 MPa and at gas ยฎelocities up to 45 cmrs indicate that the gas holdup increases with an increase in pressure, especially at high slurry concentration. At ambient pressure, a higher solids concentration signi

The conventional two-bubble-class model for bubble column reactors has been modified to account for interactions between the two bubble classes. It is shown that the modified model is more consistent with the observed residence time distribution in the gas phase than the conventional model. The resu
