摘要: Abstract Hydrodynamics of a slurry bubble column have been investigated up to concentrations 40 vol.% and gas velocities 0.26 m/s. High represent high catalyst loading increase reactor productivity, while would be required throughputs. The solid particles used are 35 μm glass beads representing typical particle size for catalytic reactors. two important hydrodynamic parameters holdup solids concentration profiles. average holdups decreased with increasing but the rate decrease slowed down higher concentrations. analysis axial profiles indicated that in due addition could attributed breakup rates. experimental compared literature correlations models. distribution followed classical sedimentation–dispersion model. Effects velocity on found minimal over range investigated.
