✦ Synopsis


The reactor size and the solid phase have an important influence on the operation behaviour of airlift-loop reactors. Liquid velocity, dispersion, local gas holdup, and local solid holdup along the reactor axis have been measured in airlift-loop rotors with outer loop and a volume of 8OL and 8OOL respectively. The measurements were done in twc+phase-systems @i&water) and threephase-systems (air,water,solid). To investigate the influence of the solid phase, Werent solid materials and different solid loadings were used_ The liquid velocity and the dispersion were compared with results gained from a 2L outer loop reactor and a 70L inner loop mactor.

## Abstract The role of the gas–liquid separator on hydrodynamic characteristics in an internal‐loop airlift reactor (ALR) was investigated. Both gas holdup and liquid velocity were measured in a 30 dm^3^ airlift reactor with two different head configurations: with and without an enlarged separator
